performcallback gridview after combobox filtering

can you help me to fix my problem, I made gridview, and I use combobox to filter data in gridview and get gridview performcallback after filter, but gridview not callback after filter. how can I do ? Help me Please?
this is some code :
controller gridview filter :
[HttpPost]
public ActionResult FilterTypePro(String typePro)
{
//Session["typePro"] = typePro;
var model = Model._ProposalObject.ListDataProposal();
if (typePro != null && typePro != string.Empty)
{
model = Model._ProposalObject.ListDataProposal(typePro);
}
return PartialView("_gvPartialViewProposals", model);
}
and this is code to get value filter combobox :
function OnClickFilter(type) {
type = cbTypeProposal.GetValue();
$.ajax({
type: "POST",
cache: false,
async: false,
url: '#Url.Action("FilterTypePro", "App")',
data: { 'typePro': type },
success: function (data) {
/*gvPartialViewProposals.AdjustControl();
try {
gvPartialViewProposals.PerformCallback();
}
catch(er){
}*/
gvPartialViewProposals.Refresh(data);
}
});
}
and this is code to view cshtml :
groupItem.Items.Add(item =>
{
item.Caption = "Type Of Proposal";
item.Width = 400;
item.SetNestedContent(() =>
{
ViewContext.Writer.Write("<table><tr><td>");
Html.DevExpress().ComboBox(cmbSettings =>
{
cmbSettings.Name = "cbTypeProposal";
cmbSettings.Width = 100;
cmbSettings.Properties.DropDownStyle = DropDownStyle.DropDownList;
cmbSettings.ShowModelErrors = true;
cmbSettings.Properties.Items.Add("ATL", "ATL");
cmbSettings.Properties.Items.Add("BTL", "BTL");
cmbSettings.Properties.ClientSideEvents.SelectedIndexChanged = "function(s, e) { OnClickFilter();}";
}).Render();
ViewContext.Writer.Write("</td></tr></table>");
});
}); ;
}).GetHtml();
I hope you can help me.

Modify your javascript function as follows:
function OnClickFilter(type){
type = cbTypeProposal.GetValue();
gvPartialViewProposals.PerformCallback({
'typePro': type
});
}
Modify your grid settings as follows:
settings.Name = "gvPartialViewProposals";
settings.CustomActionRouteValues = new { Controller = "App", Action = "FilerTypePro" };

Pass uploaded image url to javascript

I'm trying to pass my uploaded photo to javascript on a page, but I get this error. How can I fix it?
werkzeug.routing.BuildError
BuildError: ('uploaded_file', {'filename': u'user/user-1/scan.jpeg'}, None)
class AdminController(BaseController):
route_base = ''
route_prefix = '/admin'
trailing_slash = True
decorators = [login_required]
def __init__(self):
self.theme = "admin"
g.theme = self.theme
g.currentUser = g.auth.getUser()
self.viewData = {
"layout" : self.theme + "/" + "layouts/main.html"
}
class BaseMethodView(MethodView):
pass
class UserJsonDataController(AdminController, BaseMethodView):
def __init__(self):
super(UserJsonDataController, self).__init__()
def uploaded_file(filename):
return send_from_directory(app.config['UPLOAD_FOLDER'], filename)
def get(self):
json = {}
users = User.select()
a = []
for user in users:
obj = {
"user_avatar":url_for("uploaded_file", filename = user.user_avatar)
}
a.append(obj)
json["rows"] = a
return flask.jsonify(json)
module.add_url_rule('/index/show', view_func=UserJsonDataController.as_view('show'))
$(document).ready(function () {
$("#grid").kendoGrid({
dataSource: {
transport: {
read: {
url: '{{ url_for("user_admin.show") }}',
dataType: "json"
}
},
schema: {
data: "rows"
}
},
columns: [{
field: "user_avatar",
title: "Profil",
template: "<img src='/#=user_avatar #' /> "
}
});
});

I know this is old but why not. #huseyin, you mentioned that your image is located in: app/upload/user/user-1/scan.jpeg. Your url_for() first argument should match that path and in your code it's 'uploaded_file'. Try changing it to 'upload'

Jquery Context Menu ajax fetch menu items

I have a jquery context menu on my landing page where I have hardcode menu items. Now I want to get the menu items from server. Basically the idea is to show file names in a specified directory in the context menu list and open that file when user clicks it...
This is so far I have reached..
***UPDATE***
C# code
[HttpPost]
public JsonResult GetHelpFiles()
{
List<Manuals> manuals = null;
var filesPath = Server.MapPath(#"\HelpManuals");
var standardPath = new DirectoryInfo(filesPath);
if (standardPath.GetFiles().Any())
{
manuals = standardPath.GetFiles().Select(x => new Manuals
{
Name = GetFileNamewithoutExtension(x.Name),
Path = x.Name
}).ToList();
}
return Json(manuals, JsonRequestBehavior.AllowGet);
}
private string GetFileNamewithoutExtension(string filename)
{
var extension = Path.GetExtension(filename);
return filename.Substring(0, filename.Length - extension.Length);
}
JavaScript Code
$.post("/Home/GetHelpFiles", function (data) {
$.contextMenu({
selector: '#helpIcon',
trigger: 'hover',
delay: 300,
build: function($trigger, e) {
var options = {
callback: function(key) {
window.open("/HelpManuals/" + key);
},
items: {}
};
$.each(data, function (item, index) {
console.log("display name:" + index.Name);
console.log("File Path:" + index.Path);
options.items[item.Value] = {
name: index.Name,
key: index.Path
}
});
}
});
});
Thanks to Matt. Now, the build function gets fire on hover.. but im getting illegal invocation... and when iterating through json result, index.Name and this.Name gives correct result. But item.Name doesn't give anything..

to add items to the context menu dynamically you need to make a couple changes
$.contextMenu({
selector: '#helpIcon',
trigger: 'hover',
delay: 300,
build: function($trigger, e){
var options = {
callback: function (key) {
var manual;
if (key == "adminComp") {
manual = "AdminCompanion.pdf";
} else {
manual = "TeacherCompanion.pdf";
}
window.open("/HelpManuals/" + manual);
},
items: {}
}
//how to populate from model
#foreach(var temp in Model.FileList){
<text>
options.items[temp.Value] = {
name: temp.Name,
icon: 'open'
}
</text>
}
//should be able to do an ajax call here but I believe this will be called
//every time the context is triggered which may cause performance issues
$.ajax({
url: '#Url.Action("Action", "Controller")',
type: 'get',
cache: false,
async: true,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (_result) {
if (_result.Success) {
$.each(_result, function(item, index){
options.items[item.Value] = {
name: item.Name,
icon: 'open'
}
});
}
});
return options;
}
});
so you use build and inside of that define options and put your callback in there. The items defined in there is empty and is populated in the build dynamically. We build our list off of what is passed through the model but I believe you can put the ajax call in the build like I have shown above. Hopefully this will get you on the right track at least.

I solved this problem the following way.
On a user-triggered right-click I return false in the build-function. This will prevent the context-menu from opening. Instead of opeing the context-menu I start an ajax-call to the server to get the contextMenu-entries.
When the ajax-call finishes successfully I create the items and save the items on the $trigger in a data-property.
After saving the menuItems in the data-property I open the context-menu manually.
When the build-function is executed again, I get the items from the data-property.
$.contextMenu({
build: function ($trigger, e)
{
// check if the menu-items have been saved in the previous call
if ($trigger.data("contextMenuItems") != null)
{
// get options from $trigger
var options = $trigger.data("contextMenuItems");
// clear $trigger.data("contextMenuItems"),
// so that menuitems are gotten next time user does a rightclick
// from the server again.
$trigger.data("contextMenuItems", null);
return options;
}
else
{
var options = {
callback: function (key)
{
alert(key);
},
items: {}
};
$.ajax({
url: "GetMenuItemsFromServer",
success: function (response, status, xhr)
{
// for each menu-item returned from the server
for (var i = 0; i < response.length; i++)
{
var ri = response[i];
// save the menu-item from the server in the options.items object
options.items[ri.id] = ri;
}
// save the options on the table-row;
$trigger.data("contextMenuItems", options);
// open the context-menu (reopen)
$trigger.contextMenu();
},
error: function (response, status, xhr)
{
if (xhr instanceof Error)
{
alert(xhr);
}
else
{
alert($($.parseHTML(response.responseText)).find("h2").text());
}
}
});
// This return false here is important
return false;
}
});

I have finally found a better solution after reading jquery context menu documentation, thoroughly..
C# CODE
public JsonResult GetHelpFiles()
{
List<Manuals> manuals = null;
var filesPath = Server.MapPath(#"\HelpManuals");
var standardPath = new DirectoryInfo(filesPath);
if (standardPath.GetFiles().Any())
{
manuals = standardPath.GetFiles().Select(x => new Manuals
{
Name = GetFileNamewithoutExtension(x.Name),
Path = x.Name
}).ToList();
}
return Json(manuals, JsonRequestBehavior.AllowGet);
}
HTML 5
<div id="dynamicMenu">
<menu id="html5menu" type="context" style="display: none"></menu>
</div>
JavaScript Code
$.post("/Home/GetHelpFiles", function (data) {
$.each(data, function (index, item) {
var e = '<command label="' + item.Name + '" id ="' + item.Path + '"></command>';
$("#html5menu").append(e);
});
$.contextMenu({
selector: '#helpIcon',
trigger: 'hover',
delay: 300,
items: $.contextMenu.fromMenu($('#html5menu'))
});
});
$("#dynamicMenu").on("click", "menu command", function () {
var link = $(this).attr('id');
window.open("/HelpManuals/" + link);
});

Here's my solution using deferred, important to know that this feature is supported for sub-menus only
$(function () {
$.contextMenu({
selector: '.SomeClass',
build: function ($trigger, e) {
var options = {
callback: function (key, options) {
// some call back
},
items: JSON.parse($trigger.attr('data-storage')) //this is initial static menu from HTML attribute you can use any static menu here
};
options.items['Reservations'] = {
name: $trigger.attr('data-reservations'),
icon: "checkmark",
items: loadItems($trigger) // this is AJAX loaded submenu
};
return options;
}
});
});
// Now this function loads submenu items in my case server responds with 'Reservations' object
var loadItems = function ($trigger) {
var dfd = jQuery.Deferred();
$.ajax({
type: "post",
url: "/ajax.php",
cache: false,
data: {
// request parameters are not importaint here use whatever you need to get data from your server
},
success: function (data) {
dfd.resolve(data.Reservations);
}
});
return dfd.promise();
};

Defining multiple instances of a jquery ui widget on a single page

I am developing a website where I use a custom build jQuery widget to load data into multiple divs.
This is the code for the widget:
(function ($, window, document, undefined) {
$.widget ("my.contentloader", {
options: {
loading_message: true
},
_create: function () {
var that = this;
$.ajax ({
type: "POST",
url: that.options.url,
data: {data: that.options.formdata, limit: that.options.limit, offset: that.options.offset},
beforeSend: function (html) {
if (that.options.loading_message) {
$(that.options.target_area).html ("<div id='loading'>Loading</div>");
}
},
success: function (html) {
if (that.options.loading_message) {
$('#loading').remove ();
}
$(that.options.target_area).html (html);
},
error: function (html) {
$(that.options.error_area).html (html);
}
});
},
_setOption: function (key, value) {
this.options[key] = value;
$.Widget.prototype._setOption.apply (this, arguments);
}
});
})(jQuery, window, document);
I load data using the widget like this:
$('#targetdiv').contentloader ({
url: '<?php echo $action_url; ?>',
target_area: '#popup_box',
formdata: {'username' : username_email, 'password' : password}
});
I am having problems loading multiple instances on the same page.
Is there a way to not instantiate the widget on a specific div like this?
$('#targetdiv').contentloader

I think you need to assign each instance to a variable. That way, you can control each instance, or write a function that iterates over an array of instances.
var contentLoaders = [];
$('.target-div').each(function(i, data) {
contentLoaders[i] = $.widget("my.contentloader", { ... });
});
So then you should be able to operate on each loader independently, like:
for (var i in contentLoaders) {
var contentLoader = contentLoaders[i];
contentLoader.option( ... );
}
Also, you're using the DOM ID $('#loading') for multiple instances of the widget. This is wrong. You need to either use separate loaders for each widget, or else check to see if the ID exists and only insert the new node if it doesn't exist. And same for removing it.
** I've added this example block, hope it helps: **
//
// This is a way to do it if you want to explicitly define each contentloader.
// Below that, I'll write out a way to define the contentloaders in a loop.
//
var contentLoader1 = $('#targetdiv1').contentloader ({
url: '<?php echo $action_url; ?>',
target_area: '#popup_box',
formdata: {'username' : username_email, 'password' : password}
});
contentLoader1.option('url', 'http://google.com');
var contentLoader2 = $('#targetdiv2').contentloader ({
url: '<?php echo $action_url; ?>',
target_area: '#popup_box',
formdata: {'username' : username_email, 'password' : password}
});
contentLoader2.option('url', 'http:/apple.com');
// Push each widget instance into an array of widget objects
var contentLoaders = [];
contentLoaders.push(contentLoader1);
contentLoaders.push(contentLoader2);
for (var i in contentLoaders) {
console.log(i, contentLoaders[i].option('url'));
}
// Should print:
// 0 http://google.com
// 1 http://apple.com
//
//
// How to set a bunch of widgets at once from an array of content loader data
//
//
var contentLoaderData = [
{
divid: '#targetDiv1',
url: 'google.com',
formdata: {
username: 'joeshmo',
password: 'joeshmo1'
}
},
{
divid: '#targetDiv2',
url: 'apple.com',
formdata: {
username: 'plainjane',
password: 'plainjane1'
}
}
];
// Array of widget instances
var contentLoaders = [];
$.each(contentLoaderData, function(index, value) {
var contentLoader = $(this.divid).contentloader({
url: this.url,
target_area: '#popup_box',
formdata: {'username' : this.formdata.username, 'password' : this.formdata.password}
});
// Push each contentLoader instance into the contentLoaders array
contentLoaders.push(contentLoader);
});
for (var i in contentLoaders) {
console.log(i, contentLoaders[i].option('url'));
}
// Should print:
// 0 http://google.com
// 1 http://apple.com

Jquery fullcalendar not showing events

I was very excited to see a calendar plugin like fullcalendar. I am trying to use fullcalendar to display events for each month. But the events are not displayed on the calendar.
My code is :
[AcceptVerbs(HttpVerbs.Get)]
public JsonResult HighlightCalendar()
{
var tasksList = new List<HighlightMonthlyEvents>();
tasksList.Add(new HighlightMonthlyEvents
{
id = 1,
EventName = "Google search",
EventStartDate = ToUnixTimespan(DateTime.Now),
EventEndDate = ToUnixTimespan(DateTime.Now.AddHours(4)),
url = "www.google.com"
});
tasksList.Add(new HighlightMonthlyEvents
{
id = 1,
EventName = "Bing search",
EventStartDate = ToUnixTimespan(DateTime.Now.AddDays(1)),
EventEndDate = ToUnixTimespan(DateTime.Now.AddDays(1).AddHours(4)),
url = "www.bing.com"
});
var highlightDays = Jayrock.Json.Conversion.JsonConvert.ExportToString(tasksList.ToArray());
return Json(highlightDays, JsonRequestBehavior.AllowGet);
}
<script type="text/javascript">
$(function () {
// FullCalendar
$('.fullcalendar').fullCalendar({
theme: true,
header: {
left: 'today prev,next',
center: '',
right: ''
},
defaultView: 'month',
editable: false,
events: function (callback) {
// do some asynchronous ajax
contentType: "application/json; charset=utf-8",
$.getJSON("/Test/HighlightCalendar/", null,
function (result) {
var calevents = new Array();
var results = eval(result);
eval(results.length);
if (results != null) {
for (i in results) {
var calEvent = results[i];
calevents.push(calEvent)
}
}
alert(calevents.length);
// then, pass the CalEvent array to the callback
callback(calevents);
});
}
});
And as for my JSON, it looks like:
[{"id":1,"allDay":false,"title":"Google search","start":1279750267,"end":1279764667,"url":"www.google.com"},{"id":2,"allDay":false,"title":"Bing search","start":1279836667,"end":1279851067,"url":"www.bing.com"}]
What do you think about what is wrong?

This might probably has to do with quotes around your property and values.
Try to include quotes in both property and value and check your result.
I achieved the same without using JSON.js like this.
System.Web.Script.Serialization.JavaScriptSerializer eventListSerializer =
new System.Web.Script.Serialization.JavaScriptSerializer();
string eventListJSON = eventListSerializer.Serialize(addevList);
