HI
I have a question about widget object comparison :
There have FirstButton and SecondButton in the view those share the same event handler (FirstButton_Click),
How can I tell the e.sender is equals to which ?
Is the code correct or not ? if not how to do ?
View
@(Html.Kendo().Button()
.Name("FirstButton")
.Content("First")
.Events(events => events.Click("class1.FirstButton_Click"))
.HtmlAttributes(new { @type = "button" }))
@(Html.Kendo().Button()
.Name("SecondButton")
.Content("Second")
.Events(events => events.Click("class1.FirstButton_Click"))
.HtmlAttributes(new { @type = "button" }))
Javascript
FirstButton_Click: function(e)
{
// Click
var FirstButton = $("#FirstButton").data("kendoButton"), SecondButton = $("#SecondButton").data("kendoButton");
var FirstButton2 = $("#FirstButton").data("kendoButton");
//
if (e.sender == FirstButton)
alert("The sender is FirstButton");
if (e.sender == SecondButton)
alert("The sender is SecondButton");
Best regards
Chris

Hi,
I was trying to create data grid, One column is Dropdownlist. I want to pass the dynamic datasource from the Model. where Model is List<object> . But the ForeignKey cloumn accepts only SelectList as second parameter. But I want to make this dynamic i.e model.
See Below)
Current Functionality :
columns.ForeignKey(s => s.FaceId, SelectList)
I need like columns.ForeignKey(s => s.FaceId, x => x.FacesList)
Please suggest me to achieve this functionality.
Thanks
Sunder

I created a custom download via http://www.telerik.com/download/custom-download
I was under the impression that I could use this to replace a reference to kendo.all.min.js.
We're using requirejs in our app and although the kendo.all file works fine, the custom.js breaks our app. We get reference errors for kendo.data doesn't exist.
Is there fundamental difference between referencing kendo in the .all js file vs a custom download that I'm missing?

The record is removed when cancelling the edit of a new record.
JSFiddle: http://dojo.telerik.com/adAZa
Steps:
1. Click Add new Record
2. Click Update
3. Click Edit
4. Click Cancel
Record is Gone.
Click Refresh
Record is back!

I'm trying to load a large dataset (~2000 rows) on kendo ui grid - jquery. But it's creating a performance bottleneck and very jerky screen on Google chrome (performance profiling says: Forced reflow is a likely performance bottleneck). But same code/ui runs flowlessly on firefox. I've added a sample dojo.
dojo: http://dojo.telerik.com/eleNEQ/3
In this dojo please hover on the animated button after dataload.
Test criteria:
Google chrome: Version 61.0.3163.100 (Official Build) (64-bit)
Firefox: 56.0 (32-bit)
I'm wondering whether this issue can be solved by telerik. Thanks in advance.

I am using the Grid with a Filter row and I am trying to specify the column input width, but it does not work when using the Boostrap v4 theme.
Please see the following dojos where I added an inputWidth to the OrderID column.
Boostrap v3 theme (works): http://dojo.telerik.com/AmABaV
Boostrap v4 theme (does not work): http://dojo.telerik.com/AsiGi

The way our setup works updating one event might cause other events to "shift" so the server sends back all Scheduler Events that were modified. I tried just returning all of those as JSON but the scheduler doesn't seem to pick up on them.
Is there a way to sync whatever the server returned with the datasource for the scheduler? or do I just need to issue a read()
Looking at
_accept: function(result) inside kendo.data.js
I can see that it just uses the original batch of models and the index order to do updates so it can't really handle more items coming back then were sent

This is Kendo ASP MVC though the question is about DataSource.
Our code has two dropdowns. When the `onchange()` for the first fires it calls `$("#classDropDown").data("kendoDropDownList").dataSource.read();` to force the second one to update.
<%: Html.Kendo().DropDownList().Name("speciesDropDown") .DataTextField("Text") .DataValueField("Value") .DataSource(source => { source.Read(read => { read.Action("GetNLSSpecies", "RefData").Data("noFilters"); }); }) .HtmlAttributes(new { style = "width: 50%" }) .Filter(FilterType.Contains)%>...<%: Html.Kendo().DropDownList().Name("classDropDown") .DataTextField("Text") .DataValueField("Value") .DataSource(source => { source.Read(read => { read.Action("GetClassData", "RefData").Data("mergeData()"); }); }) .HtmlAttributes(new { style = "width: 50%" }) .Filter(FilterType.Contains)%>Elsewhere ...
$('#speciesDropDown').on('change', function (event) { ... $("#classDropDown").data("kendoDropDownList").dataSource.read();}The `mergeData()` function is called to provide data from the Javascript to the server. The **problem** is that because I'm calling this as a function it is **NOT** called during the `dataSource.read()`. But it is called initially when the page first loads.
Obviously I could change this to `mergeData` (ie. not a function) but it is the simplest case. I'm actually trying to pass arguments, something like:
.Data("mergeData('getSpeciesDropdownObj','getShownOrRequired(\"OtherClass\")')")This seems like a bug to me. Does it to you?
I originally posted this at https://stackoverflow.com/questions/48087808/mvc-kendo-grid-read-action-datafunction-not-called-on-a-forced-datasource-re and had a conversation about though the question didn't really get answered. (I have since been given a login so I can post here).
