Had troubles with the Excel-like filters in the RadGrid when trying for the first time.  The context menu wouldn't drop down after configuring RadGrid based on this text from the demo:

The demo shows the new Grid FilterType called HeaderContext implemented in Q3 2015. This filtering mode provides look and feel that resembles the filter in Excel. To enable this mode you should set the FilterTypeproperty of RadGrid to HeaderContext and turn on the header context menu (EnableHeaderContextFilterMenu="true").

After troubleshooting and comparing code, found it didn't drop down because  EnableHeaderContextMenu="true"  was missing from my markup but was is in the demo .aspx code.

It would be helpful to update the demo page and add EnableHeaderContextMenu="true" to the list of required properties.

I think adding more info about the need for this event... OnFilterCheckListItemsRequested="RadGrid1_FilterCheckListItemsRequested" in the same text would also help.  The text of As you can see ListBox populated through DataSource displays the values. doesn't highlight the importance of that event to the Excel-like filtering feature.

Thanks,

John

I have a problem in that when I have a RadGrid inside a RadWindow with Firefox. With FireFox I can't seem to resize the radgrid properly. The resizing works fine in IE.

For example, have a RadWindow that I open ("ClientSearch") Width=600 Height=450. In my example I am (for testing purposes) setting the RadGrid to Width=100 Height=100.

This screencap shows how it renders in IE.

This screencap shows how it renders in FireFox.

(I also attached files)

 Could anyone tell me what I'm doing wrong? Is there another way to resize the radGrid?

Cutting to it, here is the Javascript I use to resize, the main page that defines the Window, and the code snipplet in the window that defines the grid. On the page that I define the grid I do <ClientEvents OnMasterTableViewCreated="SetGridSizeLocator"> .. this is what calls the Javascript.

Hi All.

How do i download the demo of this, as i only have updated my Telerik, but i want to download the full demo that you have, as i have not downloaded any demos.

I use item.Display = false; in the RadGrid1_ItemCreated. This hides the item fine. Page count is 15 and only shows 10 because 5 are hidden.

Is there a way to show the 15 requested...

Thanks

We are doing some work for a client who has a number of web applications which were initially built in .net 2.0 and which use Telerik 2009.1.402.20.

As part of some minor changes to the applications. We also upgraded to .net 4.0. This has caused a number of issues with the telerik controls and we are assuming that there are compatibility issues between this version and .net 4.0. 

We tried to fix a number of issues by using the known _DestoryTree JS fix. However this doesn't seem to have worked for many of the issues. 

Could someone please advise on the following:

1 - Is there anyway around the incompatibility?

2 - If not and an upgrade in Telerik is required will this in itself cause other issues with the migration from the old version to the new? Are there issues with backward compatibility.

Thanks for your help.

RadComboBox not rendered (Rendered as "") when within asp panel with initial visible= false.

The asp panel is set to visible= true when postback is triggered via client using ajaxManager.ajaxRequest('InitialPageLoad'

}

The panel has other server side control but they render fine. 

If I set radComboBox1.visible = true then it works fine. But should it automatically render and no need for setting specificly

function initializePage(sender, eventArgs) {                 var ajaxManager = $find('<%= RadAjaxManager.GetCurrent(this.Page).ClientID %>');                 ajaxManager.ajaxRequest('InitialPageLoad');   
          }

<telerik:AjaxSetting AjaxControlID="radAjaxManager1">  
 <UpdatedControls>         
        <telerik:AjaxUpdatedControl ControlID="pnlWithComboBox"  />   
  </UpdatedControls>  
 </telerik:AjaxSetting>
