System.Data.Entity.DynamicProxies

I tried this code in my controller Can any one show me the solution:
public JsonResult GetMembers(Member member)
{
//var list = repository.GetAll().Select(x => new ViewModel.MemberView
//{
// Memberid = x.id,
// Name = x.name,
// EmailAddress = x.Email,
// Role = x.role.rolename,
// ReportingRoleId = Convert.ToInt32(x.reportingroleid)
//});
var list = repository.GetAll();
return Json(list , JsonRequestBehavior.AllowGet);
}
javascript function
<script type="text/javascript">
debugger;
alert('first');
google.load("visualization", "1", {packages:["orgchart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
$.ajax({
type: "POST",
url: "/Organization/GetMembers",
data :'{member:"+JSON.stringify(member)+"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
alert("Member Name"+data);
//var data = new google.visualization.DataTable();
//data.addColumn('string','name');
//data.addColumn('string', 'role');
//data.addColumn('string', 'ToolTip');
//for (var i = 0; i < r.length; i++) {
// var memberId = r[i][0];
// var Name = r[i][1];
// var role= r[i][2];
// var reportingrole= r[i][3] != null ? r[i][3].toString() : '';
// data.addRows([[{
// v: employeeId,
// f: Name + '<div>(<span>' + role + '</span>)</div><img src = "/Pictures/' + memberId + '.jpg" />'
// }, reportingrole, role]]);
//}
// var chart = new google.visualization.OrgChart($("#chart")[0]);
// chart.draw(data, { allowHtml: true });
},
failure: function (r) {
alert(r);
},
error: function (r) {
alert(r);
}
});
}
It was Error
A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.NewProjects_A3B55EADDAEF6C59245BBD2495E29ECFE10B583596DB24AADF23A4990342D104'.

I had the same error, but this is worked for me, this is when you want to select
public MyDbContext() : base("name=MyDbContext"){this.Configuration.ProxyCreationEnabled = false;}
before you call yout table use this this.Configuration.ProxyCreationEnabled = false;

You should convert your data to list before returning it. EF return proxies for lazy loading and stuff. Try below code.
var list = repository.GetAll().ToList();
Also Look at this.
Why is EF returning a proxy class instead of the actual entity?

View is not passing the model to controller - ASP.Net MVC

This is a basic passing of values from view to controller, but this does not seek to work.When I click the update button that functions to update the record in the database, the values from view, does not correctly pass the values to controller. Upon putting debugger in the javascript, the each variables were able to correctly got its values and evn the object where they are stored.
What could possible the reason for this problem?
here's the button onclick event code in Javascript.
$('#updatePrescription').click(function () {
debugger;
ValidateFields();
var drugListIsEmpty = CheckDrugList();
var error = $(".text-danger").length;
if (error == 0 && !drugListIsEmpty) {
debugger;
var prescription = [];
var template = {};
template.templateName = $("#prescriptionTemplateName").val();
template.templateTypeId = $('input[name=templateTypeId]:checked').val();
template.prescriptionTemplateItemList = [];
template.instructionId = $('.instruction').val();
template.frequencyId = $('.frequency').val();
template.day = $('.inputDays').val();
template.quantity = $('.inputQuantity').val();
template.dispenseLocationId = $('.selectDispenseLocation').val();
template.statusId = $('.status').val();
//template.categoryId = $('.templateCategory').filter(":visible").last().val();
template.templateId = $('#prescriptionTemplateId').val();
//if (template.categoryId == null) {
// template.categoryId = 0;
//}
var x = 0;
$('#tblPrescriptionSaveTemplateBody tr').each(function (key, value) {
debugger;
var row = $(this).closest('tr');
var next_row = $(row).next();
var drugId = $(value).find('.drugId').val();
var dosage = $(value).find('.inputDosage').val();
var dosageUnitId = $(value).find('.selectUnitId').val();
var statusId = "41";
var remarks = $(value).find('.inputDescription').val();
var groupId = $(value).find('.inputGroupNo').val();
var unit = $(value).find('.selectUnitId').val();
var prescriptionTemplateItemId = $(value).find('.prescriptionTemplateItemId').val();
x++;
var obj = {
// templateId: prescriptionTemplateId,
prescriptionTemplateId: template.templateId,
prescriptionTemplateItemId: prescriptionTemplateItemId,
drugId: drugId,
dosage: dosage,
dosageUnitId: dosageUnitId,
instructionId: template.instructionId,
frequencyId: template.frequencyId,
day: template.day,
quanitity: template.quantity,
unit: unit,
remarks: remarks,
dispenseLocationId: template.dispenseLocationId,
groupId: groupId,
statusId: template.statusId
}
template.prescriptionTemplateItemList.push(obj);
//prescription.push(obj)
})
$.ajax({
type: 'POST',
url: '/WestMedicinePrescriptionTemplate/UpdateTemplate',
dataType: 'json',
contentType: 'application/json',
data: JSON.stringify(template),
success: function (data) {
ShowNotificationMessage(data.notification);
window.location.href = '/WestMedicinePrescriptionTemplate/Index';
}
});
}
});
This is expected to pass the result of model in parameter "newtemplate" in the controller, but it results to null
public ActionResult UpdateTemplate([FromBody] PrescriptionTemplateVM newtemplate)
{
int empId = Convert.ToInt32(HttpContext.Session.GetInt32("EmployeeId"));
var notif = "Update Failed.";
try
{
if (ModelState.IsValid)
{
bool updateSuccessful = _prescription.UpdatePrescriptionTemplateAndItems(newtemplate, empId);
if (updateSuccessful)
{
notif = "Update Successful.";
}
}
}
catch (Exception ex)
{
notif = ex.Message;
}
return Json(new { notification = notif });
}
What could be the problem in the code

do like this:
[HttpPost]
public ActionResult UpdateTemplate(PrescriptionTemplateVM newtemplate)
You need to make sure that you are using the same variables names that you defined in PrescriptionTemplateVM
and dont convert the data to Json. do like this:
$.ajax({
type: 'POST',
url: '/WestMedicinePrescriptionTemplate/UpdateTemplate',
dataType: 'json',
contentType: 'application/json',
data: {newtemplate: template},
success: function (data) {
ShowNotificationMessage(data.notification);
window.location.href =
'/WestMedicinePrescriptionTemplate/Index';
}
});

How to get selected row values from a table

I am converting a HTML table to an array and passing it in to a controller for inserting multiple rows. I am able to create the array, but the problem is it's creating a complete table array but I want to get the selected row td values only.
//function to convert HTML table to array//
var HTMLtbl = {
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function(rowIndex, r) {
var cols = [];
// I believe the main problem is here:
$(this).find('td').each(function(colIndex, c) {
cols.push($(this).text().trim());
});
data.push(cols);
});
return data;
}
}
$(document).on('click', '#btnsave', function() {
var data = HTMLtbl.getData($('#tblresult'));
var parameters = {};
parameters.array = data;
var request = $.ajax({
async: true,
cache: false,
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
url: "../Home/Save_SearchCarsDocs",
data: JSON.stringify(parameters)
});
request.done(function(msg) {
alert("Row saved " + msg.d);
});

You can try following...
//function to convert HTML table to array//
var excludedTD_Index = [0,5,7]; // define what you want to exclude by index
var HTMLtbl = {
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function(rowIndex, r) {
var cols = [];
// I believe the main problem is here:
$(this).find('td').each(function(colIndex, c) {
if(excludedTD_Index.indexOf(colIndex) >=0) // exclude TD
continue;
cols.push($(this).text().trim());
});
data.push(cols);
});
return data;
}
}
$(document).on('click', '#btnsave', function() {
var data = HTMLtbl.getData($('#tblresult'));
var parameters = {};
parameters.array = data;
var request = $.ajax({
async: true,
cache: false,
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
url: "../Home/Save_SearchCarsDocs",
data: JSON.stringify(parameters)
});
request.done(function(msg) {
alert("Row saved " + msg.d);
});
OR you can make it more managable if you can add following data to your TD tag
<td data-exclude="1">
...
after adding above data you can exclude those columns as following
var HTMLtbl = {
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function(rowIndex, r) {
var cols = [];
// I believe the main problem is here:
$(this).find('td').each(function(colIndex, c) {
if($(this).data("exclude") == 1) // exclude TD
continue;
cols.push($(this).text().trim());
});
data.push(cols);
});
return data;
}
}

thanks Rory McCrossan finally get my answer i am adding my solution below
var CB=1;
var HTMLtbl =
{
getData: function (table) {
var data = [];
table.find('tr').not(':first').each(function (rowIndex, r) {
if ($("#chk_" + CB).is(':checked'))
{
var cols = [];
$(this).find('td').each(function (colIndex, c) {
cols.push($(this).text().trim());
});
data.push(cols);
}
CB++;
});
CB = 1;
return data;
}
}

fuzzy search (fuse.js) using XML instead of JSON

Is it possible to use like fuse.js with an XML document instead of JSON? As it is now I only have an XML document with data and hope that I shouldn't make a new version as well for JSON.
Hope someone can help me out which direction I can/should go.
Kind regards,
Niels

Found the solution myself. Instead of the example with JSON placed on http://kiro.me/projects/fuse.html, here is the version with an XML call instead :)
$(function() {
function start(books) {
var $inputSearch = $('#hero-search'),
$results = $('#results ul'),
$authorCheckbox = $('#value'),
$titleCheckbox = $('#typeId'),
$caseCheckbox = $('#case'),
searchAuthors = true,
searchTitles = false,
isCaseSensitive = false,
fuse;
function search() {
$results.empty();
$.each(r, function(i, val) {
$resultShops.append('<li class="result-item"><span><img src="' + this.statusId + '" /></span> ' + this.value + '</li>');
});
}
function createFuse() {
var keys = [];
if (searchAuthors) {
keys.push('value');
}
if (searchTitles) {
keys.push('typeId');
}
fuse = new Fuse(books, {
keys: keys,
caseSensitive: isCaseSensitive
});
}
$inputSearch.on('keyup', search);
createFuse();
}
$.ajax({
type: 'GET',
dataType: 'xml',
url: 'xml-document/document.xml',
success: function(response) {
var suggestions = [];
$(response).find("searchResults").children().each(function(i, elm) {
var name = $(elm).find('name').text();
var url = $(elm).find('url').text();
var description = $(elm).find('description').text();
var statusId = $(elm).find('status').text();
var typeId = $(elm).find('type').text();
var result = {};
result.value = name;
result.url = url;
result.description = description;
result.statusId = statusId;
result.typeId = typeId;
suggestions.push(result);
});
start(suggestions);
},
error: function(response) {
console.log('failure',response);
}
});
});

Url.Action Passing string array from View to Controller in MVC#

I have a method that returns an array (string[]) and I'm trying to pass this array of strings into an Action.Currently I can't pass my parameters. I am new in MVC3.
Pls let me know why I can't pass parameter to ActionResult..I already define ActionResult with Same parameter name..
thanks all in advance....
$('#export-button').click(function () {
var columnLength = $("#grid")[0].p.colNames.length;
var columnNames = "";
for (var i = 0; i < columnLength; i++) {
if ($("#grid")[0].p.colModel[i].hidden == false) {
columnNames = columnNames + $("#grid")[0].p.colModel[i].name + ',';
}
}
var Val1 = jQuery(txt_search1).val();
alert(Val1); alert(columnNames);
document.location = '#Url.Action("OrgDataExport","Search", new { Val1 = Val1 , columnNames = columnNames})';
});

Try this,
$('#export-button').click(function () {
var columnLength = $("#grid")[0].p.colNames.length;
// columnNames is an object now
var columnNames = {};
for (var i = 0; i < columnLength; i++) {
if ($("#grid")[0].p.colModel[i].hidden == false) {
columnNames[i] = $("#grid")[0].p.colModel[i].name;
}
}
var Val1 = jQuery(txt_search1).val();
document.location = "Home/Index/" + $.param({ Val1 = Val1 , columnNames = columnNames });
});
Your action that takes columnNames as a string array
public ActionResult Index(string val1, string[] columnNames)
{
// Your code
}
UPDATE:
If the URL becomes too big you can submit the values through form using POST method. If your view already have a form use that else create a dynamic one on the fly and submit the values through POST.
$('#export-button').click(function () {
var Val1 = jQuery(txt_search1).val();
$("#hidden-form").remove();
// create a form dynamically
var form = $('<form>')
.attr({ id: "hidden-form",
action: "/Home/Index",
method: "post",
style: "display: none;"
})
.appendTo("body");
// add the "Val1" as hidden field to the form.
$('<input>').attr({ name: "Val1 ", value: Val1, type: "hidden" }).appendTo(form);
var columnLength = $("#grid")[0].p.colNames.length;
// add the "columnNames" as hidden fields to the form
for (var i = 0; i < columnLength; i++) {
if ($("#grid")[0].p.colModel[i].hidden == false) {
var t = $("#grid")[0].p.colModel[i].name;
$('<input>').attr({ name: "columnNames", value: t, type: "hidden"
}).appendTo(form);
}
};
// submit the form
form.submit();
});

for (var i = 0; i < columnLength; i++) {
if ($("#grid")[0].p.colModel[i].hidden == false) {
columnNames = columnNames + $("#grid")[0].p.colModel[i].name + ',';
}
}
var Val1 = jQuery(txt_search1).val();
alert(Val1); alert(columnNames);
document.location = '#Url.Action("OrgDataExport","Search", new { Val1 = Val1 , columnNames = columnNames})';
Hi Louis,
Your are trying to access javascript varaibles Val1 and columnNames from the server side tag and it is not possible. For more details, please refer this URL.
You can do it by following way.
var jsonData = { val1 : Val1, columnNames : columnNames };
$.ajax({
type: "GET", //GET or POST or PUT or DELETE verb
url: "Home/Index", // Location of the service
data: jsonData,
contentType: "application/json; charset=utf-8", // content type sent to server
processdata: true, //True or False
success: function () {
alert("success")
}
});
On your controller side you have to write like
public ActionResult Index(string val1, string columnNames)
{
// Your code
}

You tagged JQuery-Ajax but i don't see any ajax attempt in the code example? So i am guessing you want to know an Ajax orientated solution. You're probably not using Zend Framework, but i hope this answers helps point you in the right direction to a solution.
From JS/Zend framework experience you could look at something like
$('#export-button').click(function () {
....
var actionUrl= "/controller/action/";
$.ajax({
url: actionUrl,
data: {
variable1: "OrgDataExport",
variable2: "Search",
Val1: Val1,
columnNames: columnNames
},
dataType: "json",
success: function(json) {
//do stuff
}
});
....
});
In the ZendFramework controller you can then grab the variables on the request:
$Val1 = $this->_request->getparam("Val1");
