How do get the underlying data from a row click on a grid?
My code looks like this :
isc.ListGrid.create({
ID: "countryList",
width:1500, height:224, alternateRecordStyles:true,
data: sampleData,
fields:[
{name:"id", title:"Id"},
{name:"name", title:"Name"},
{name:"version", title:"Version"},
{name:"release", title:"Release"},
],
canReorderFields: true,
click: function (x) {
alert('hi there' + x)
}
})
If I add a click function, the alert pops up.
If put in a paramater 'x', and that seems to have some kind of value, but i can't decipher it means. What I really want is the underlying JSON data (see below) which is being passed in as sampleData.
{
id:"10621",
name:"PimsPacket020",
version:"0.1",
release:"undefined",},
{
id:"10621",
name:"PimsPacket020",
version:"0.1",
release:"undefined",
}
I haven't been using Smartclient for quite some time, but, I think a better selection event for a grid row would be:
selectionChanged: "someFunction(this.getSelection())"
The this.getSelection() function will return an array of records even for a single selection.
For more information I suggest using the Smartclient on-line documentation( Smartclient 9.1 Documentation) and feature explorer(Smartclient Feature Explorer) together. This code work on earlier versions; from 8.x at least.
I hope this helps.
if your list contains chexbox (selectionAppearance: "checkbox") you have to use this.getSelection() that contain all selected items.
or you make a function with record parameter:
click: function (record) {
isc.say ("ID:" + record.id + "Name:" + record.Name);
}
Use this function to retrieve your record
recordClick: function (viewer, record, recordNum, field, fieldNum, value, rawValue) {
alert('hi there' + record.name);
}
For more information, please refer smartclient documentation

I am working on setting up a scenario as following:
1) User is shown existing results on first grid
2) User can select multiple results and click an 'Edit' button which will extract the selected items from the first grid
3)Second grid will be populated with the rows the user has selected from the first grid and will allow them to make edits to the content
4)Pressing save will update the results and show the first grid with the rows updated
So far using drips and drabs of various forum threads (here and here), I have managed to accomplish the first two steps.
$("#editButton").kendoButton({
click: function () {
// extract selected results from the grid and send along with transition
var gridResults = $("#resultGrid").data("kendoGrid"); // sourceGrid
var gridConfig = $("#resultConfigGrid").data("kendoGrid"); // destinationGrid
gridResults.select().each(function () {
var dataItem = gridResults.dataItem($(this));
gridConfig.dataSource.add(dataItem);
});
gridConfig.refresh();
transitionToConfigGrid();
}
});
dataItem returns what i am expecting to see with regards to the selected item(s) - attached dataItem.png. I can see the gridConfig populating but with blank rows (gridBlankRows.png).
gridConfig setup:
$(document).ready(function () {
// build the custom column schema based on the number of lots - this can vary
var columnSchema = [];
columnSchema.push({ title: 'Date Time'});
for(var i = 0; i < $("#maxNumLots").data("value"); ++i)
{
columnSchema.push({
title: 'Lot ' + i,
columns: [{
title: 'Count'
}, {
title: 'Mean'
}, {
title: 'SD'
}]
});
}
columnSchema.push({ title: 'Comment'});
columnSchema.push({ title: 'Review Comment' });
// build the datasource with CU operations
var configDataSource = new kendo.data.DataSource({
transport: {
create: function(options) {},
update: function(options) {}
}
});
$("#resultConfigGrid").kendoGrid({
columns: columnSchema,
editable: true
});
});
I have run out of useful reference material to identify what I am doing wrong / what could be outstanding here. Any help/guidance would be greatly appreciated.
Furthermore, I will also need functionality to 'Add New' results. If possible I would like to use the same grid (with a blank datasource) in order to accomplish this. The user can then add rows to the second grid and save with similar functionality to the update functionality. So if there is any way to factor this into the response, I would appreciate it.
The following example...
http://dojo.telerik.com/EkiVO
...is a modified version of...
http://docs.telerik.com/kendo-ui/framework/datasource/crud#examples
A couple of notes:
it matters if you are adding plain objects to the second Grid's dataSource (gridConfig.dataSource.add(dataItem).toJSON();), or Kendo UI Model objects (gridConfig.dataSource.add(dataItem);). In the first case, you will need to pass back the updated values from Grid2 to Grid1, otherwise this will occur automatically;
there is no need to refresh() the second Grid after adding, removing or changing its data items
both Grid dataSources must be configured for CRUD operations, you can follow the CRUD documentation
the Grid does not persist its selection across rebinds, so if you want to preserve the selection in the first Grid after some values have been changed, use the approach described at Persist Row Selection
Is there a way to use HTML5's localstorage method with Jquery's select2 plugin? Right now when I enter data and close the browser/tab, all entered data is gone, which is not so optimal since it can get confusing if you dont remember what you've entered
My select2 code looks like this:
$(".select").select2({
minimumInputLength: 1,
multiple: true,
query: function(query){
$.getJSON( 'url path to remote API', {
name:query.term,
featured:true
}, function(results){
var data = {results: []};
$.each(results.data, function(index, item){
data.results.push({id: item.artist_id, text: item.name});
});
query.callback(data);
} );
}
});
Any help is very appreciated
give this a try: http://jsfiddle.net/7267rkxy/12/
I commented the code for you for some explanation of what's going on, you should be able to just swap out the data option with your query option and it should still work
PS: I noticed none of your answered questions have been marked 'accepted', if someone gives you an answer that you like or that works for you, you should mark their answer 'accepted' by clicking the checkbox next to the answer
HTML
<!-- setting a hard width for example -->
<input type="text" class="select" style="width:200px;" value="" />
JS
// set value property to local storage value
$(".select").val(localStorage.s2options);
$(".select").select2({
minimumInputLength: 1,
multiple: true,
data: [{id: 1, text: 'option1'},{id: 2, text: 'option2'},{id: 3, text: 'option3'}], //sample data
initSelection: function (element, callback) {
// initSelection only fires when there is something in the value property
callback($.parseJSON(element.val()));
}
}).on('change', function(info){
// checking if we have anything stored in local storage
var s2options = localStorage.s2options ? JSON.parse(localStorage.s2options) : [];
// add / remove options
if (info.added) {
s2options.push(info.added);
} else if (info.removed) {
s2options = s2options.filter(function(opt) {
return opt.id != info.removed.id;
});
}
// save selections to local storage
localStorage.s2options = JSON.stringify(s2options);
});
In addition to #bruchowski 's answer, the newer version of Select2 has a different way of doing this (initSelection and query are still supported for backwards compatibility though):
You have to create a custom DataAdapter and implement current() and query().
I'm using the jqGrid columnChooser, like so:
jQuery(grid).jqGrid(
'navButtonAdd',
pagerDiv,
{
caption: "Columns",
buttonicon: "ui-icon-newwin",
title: "Hide/Show Columns",
onClickButton: function () {
$(this).jqGrid('columnChooser', {
done: function (perm) {
if (perm) {
$(this).jqGrid('remapColumns', perm, true);
}
},
modal: true,
width: 400,
height: 300,
classname: 'column-chooser-select'
});
}
}
);
and was wondering if there was a way to specify an event handler on the columnChooser (using the jQuery UI Multiselect plugin that comes w/ jqGrid) that fires any time a column is either added or removed. So I guess it's a two-part question:
does the jQuery UI Multiselect support such a thing?
if so, is there a way to hook it up without altering the jqGrid source?
A bit of background on what I'm trying to achieve:
My default grid configuration hides many columns. Some of these columns are not populated from the db - they are obscure, rarely used data elements that if populated would dramatically decrease the query execution performance (multiple joins involving tables with 100 million plus records).
Should a user pick one of these columns for display i'd like to warn them that another roundtrip to the server is required and it could take a while - and give them the option to cancel the column addition.
Thanks
I think I understand your problem and find your question interesting, so I wrote the demo for you which shows how one can solve the problem.
columnChooser uses jQuery UI Multiselect plugin internally which uses jQuery UI Sortable. So I suggest to use sortreceive event of the jQuery UI Sortable to catch the information needed.
The code can be the following
$("#grid").jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
onClickButton: function () {
$(this).jqGrid('columnChooser');
$("#colchooser_" + $.jgrid.jqID(this.id) + " ul.selected")
.bind("sortreceive", function (event, ui) {
alert('column "' + ui.item.text() + '" is choosed');
});
$("#colchooser_" + $.jgrid.jqID(this.id) + " ul.available a.action")
.click(function () {
alert('column "' + $(this).parent().text() + '" is choosed');
});
}
});
See the demo here.
The code bind 'click' event on the "+" for the initial list of the columns which was in the column chooser at the initialization time of the dialog. I think it would be sufficient for you. If needed you can easy modify the code to support the 'click' on the "+" for the columns which will be removed from the left list during the work with the columnChooser.
I almost forget to mention that I used in the demo improved version of the columnChooser (see the answer), but my above suggestion works with the original version of columnChooser too.
I am using the below code in JqGrid for column chooser plug-in. when i tick the select All check box in the grid. I want to exclude particular column ( by default it should not display in my grid).
I used hidden=True property in col model. buy i want to handle these in column chooser also.
function Properties_Columnchooser() {
$('#btn_setColumns').click(function () {
jQuery('#grid-tableProperties').jqGrid('columnChooser',{
"shrinkToFit" : true,
"autowidth" : true,
done : function(perm) {
w = $(window).width();
// alert('done ' + w);
if (perm)
{
this.jqGrid("remapColumns", perm, true);
this.setGridWidth(w - 30, true);
$('.ui-search-input').show();
}
else
{
}
}
}
);
});
}
Updated
I have problems to point data with the custom formatter.
I am using jqgrid's custom formatter.
function myformatter ( cellvalue, options, rowObject )
{
....
Now, my custom formatter seems to point always on the last row of the grid. In fact, if I get rowObject[0], for example, I have the value of the [column 0, last row] of my grid. Why?
The grid's data is correctly compiled and I already checked Json object content.
Here's my custom formatter:
......
{ name: 'act', index: 'Detail', width: 50, sortable: false, search: false,
formatter: function (cellvalue, options, rowObject) {
i = options.rowId;
var tst = '<a class="nau" name="nau" onClick="alert(i);return false;" href="#"></a>';
var det = '<a class="det" name="det" onClick="alert(this.name);return false;" href="#"></a>';
return tst + det;
}
}
....
Update
I noticed that the formatter works fine if I return the string I want directly (for example return rowObject[0] works fine), while I have problems when I use variables. Moreover, if I try to do onclick=alert(rowObject[0]) I get an exception saying rowObject does not exists. I think this is the problem: if I set t = rowObject[0], then the formatter use t as static variable instead of updating it for each row. The same if I set i = options.rowId, where i remains static...WHY? What I should do?
I succeed to get it work...I must say that I feel a little embarrassed ... it was a stupid mistake. I hope we can still help some inexperienced like me, anyway. I did not put variables outside of quotes:
......
{ name: 'act', index: 'Detail', width: 50, sortable: false, search: false,
formatter: function (cellvalue, options, rowObject) {
i = options.rowId;
var tst = '<a class="nau" name="nau" onClick="alert('+i+');return false;" href="#"></a>';
var det = '<a class="det" name="det" onClick="alert(this.name);return false;" href="#"></a>';
return tst + det;
}
}
....
I quote the precious help from #Oleg: "The code in onclick will be executed separately so you have to use values of the variables and not the names. For example 'onclick="alert(rowObject[0]);return false;"' will produce error because global array rowObject is not exist. You have to change the code to use 'onclick="alert(' + rowObject[0] + ');return false;"' which will place the value of rowObject[0] in the code."
I suppose that you have some problems in filling of the grid. If options.rowId is the same for all rows then you fill the grid with the wrong data where the id is always 1.
If you will don't localize the wrong place in your code you should include the code and the test data which you use.
Moreover you should use onclick instead of onClick. Your current code can work now, but it will be not more work it your would change the DOCTYPE.
My flexigrid is setup. All I need is an event that gets called when the user clicks on a row. From there, I will send the user to another page based on the data contained in that row. But I can't seem to find any examples on how to do this.
I'm looking for a clear example on how to handle row onclick events using flexigrid.
I'm also interested in any other javascript table frameworks that could be used in this situation. I've been taking a peek at DataTables and it looks like it may be a better alternative (and the project appears to be more active)
In the initial setup for the flexigrid, add the attribute process: procMe to the column model. Example:
colModel : [
{ display: 'Request', name : 'id', process: procMe }
]
and then create a callback:
function procMe( celDiv, id ) {
$( celDiv ).click( function() {
alert( id );
});
}
A better solution
Adding process to colModel didnt work for me.
colModel : [
{ display: 'Request', name : 'id', process: procMe }
]
this solution below is what I'm using:
var gridRows = $("#data-grid tbody tr");
gridRows.click(function (event) {
displaySelectedItem($(this).attr('id').substr(3));
return false; //exit
});
Flexigrid column as link
colModel: [
{
display: 'DomainName', name: 'DomainName', width: 180,
sortable: true, align: 'left',
process: function (col, id)
{
col.innerHTML = "<a href='javascript:domainEdit(" + id + ");'
id='flex_col" + id + "'>" + col.innerHTML + "</a>";
}
}]
Link Function
function domainEdit(domainID) {
alert('domainID' + domainID);
}
I think this variant little better than whoabackoff
$('.TableName').click(function(event){
$('.res').html('dbl');
alert('dbl');
});
does this help? http://www.flexigrid-asp.net/demo/updatepanel.aspx
you can have a look at it with firebug, to see where the event is hooked.
keep in mind that the flexigrid.js file is a bit different than the one from the official project.
