Single select only;tooltip on nodes; find and select node

1. Single Select: I want user to select only one node and if user selects another then previous one is deselected. I am using Entry_Added event and can clear the entries but not sure how to select entry. I looks like I need to use both clientside and serverside events. How can I allow single select?

2 Tooltip on nodes: How can I show tooltip on nodes? The tooltip for control is there but I can't find any property for nodes.

3. Is it possible to find and select the node with node value. There is no property called Nodes and find Entries collection. how can show the checkbox checked for a node with a specific value?

</ParentTableRelation>

</telerik:GridTableView>

</DetailTables

My object data source

<asp:ObjectDataSource id="dsMain" runat="server" selectmethod="GetRootCategories" deletemethod="DeleteCategory"

typename="Ascent.Catalog.Model.DataModel.Categories">

<deleteparameters>

<asp:Parameter Name="ID" Type="Int32"/>

Export to Excel - 'Cols' is null or undefined

Hi, I'm hoping someone out there can help me...

I've got a radgrid and in the <CommandItemTemplate> I have a button with CommandName="ExportToExcel"

... In the code behind, I capture the radgrid1.ItemCommand

Select Case e.CommandName

            Case "ExportToExcel"

		RadGrid1.ExportSettings.ExportOnlyData = True
		RadGrid1.ExportSettings.IgnorePaging = True
		RadGrid1.ExportSettings.OpenInNewWindow = True

		RadGrid1.MasterTableView.ExportToExcel()

but whenever I hit the button, I get an error within what I assume is part of the Telerik code...

Microsoft JScript runtime error: Unable to get value of the property 'Cols': object is null or undefined

RadGrid layout breaks on postback in Q2 2013 release.

We have discovered a problem in the RadGrid rendering that appears in various scenarios in Q2 2013 release. The issue appears on post back and causes broken RadGrid layout. The problematic behavior is caused by the <FilterMenu></FilterMenu> tag which is automatically added when RadGrid is created from the designer. In case the official Q2 2013 version is used in your application you need to remove the mentioned tag from the RadGrid markup in order to fix the problem.
Official fix for the presented issue is already added to the latest internal build of the controls.

Cascading dropdown within gridview

With the standard Visual Studio tools, it is difficult to implement a cascading dropdown list within a gridview. The second dropdownlist can not be bound to the datasource and instead you have to perform some code behind to make it work correctly. Does the Telerik grid control handle this scenario properly or do you have to do code behind also? I don't currently own the controls but would purchase them if they can handle this.
