I am using Version 2013  of telerik webUI and the frame work for my web application is .Net framework 3.5. Issue is when im opening the particular .aspx form in internet explorer it is appearing proper, but in firefox and chrome it appears weird. FYR screenshot is attached.

i need to insert new dataitem to the existing kendo gantt data source. but i cant able to do. i have used javascript splice method also, but not working $("#gantt").data("kendoGantt").dataSource.fetch(function () { //newJsonData contains the objects for insertion $.each(newJsonData, function (i, row) { //insert data to gantt data source this._data.pop(newJsonData[i]); }); });

Hi,

I use the 2015.1.401.40 version of your ASP.NET for AJAX controls.

If it matters, I'm currently binding it to a SQLDataSource.

From what I see, the entire PivotGrid does a PostBack when you:

- click a filter to display the Filter Popup

- expand or collapse a row or column field to show or hide detail

Why does it postback???  When I expand a row to show detail, and then collapse it, there is no reason to post back.  I'm not even rebinding on postback.  Why doesn't the control just use javascript to hide the detail.

The same with the filter popup... when you click the filter icon, why not just display a div that you could have put in the page when the control was initially bound?  Why do a postback to then just display the filters in a popup?

Am I missing something or doing something wrong?  Most of you other controls (hierarchical grid or grid with grouping​), they are able to hide / show children or grouped rows on the client.  Why doesn't the pivot grid?

Thanks,

Brent

Hi,

Recently I upgraded to Version 2015.1.401.45.  After this upgrade, a column with name 'IsNew'  that should be hidden. was displayed, although in the version before it is not displayed.

When debugging, I found out, that this column is renamed automatically to IsNew1. There is no other column with the same name in my datasource.

So I suppose, that with the new version IsNew is recognized to be a keyword??

 This is the method for hiding columns:

I have on treview, i select one node to drag to asp text box but dosent work on firefox, in IE and Crome works fine.

Hi,

 I have a RadWindow which opens up on the click event of a rad button present in each row of a RadGrid.

The RadWindow doesn't open on the single click for the first time (it takes double click for the first time) and opens in single click the next time.

Please see the code below and not sure if I am missing some thing.

Thanks!
