How can I select a single row in Radgrid using checkbox? I am using gridtemplate column to show checkbox in the grid as below.

<telerik:GridTemplateColumn AllowFiltering="false">

<ItemTemplate>

<asp:CheckBox runat="server" ID="CheckBoxColumn" OnCheckedChanged="CheckBoxColumn_CheckedChanged" AutoPostBack="true" />

</ItemTemplate>

</telerik:GridTemplateColumn>

But here I need to select only a single row in the grid.While checking a checkbox,I need to uncheck the previously checked checkbox in grid.

Please help me on this.
Thanks,
Soumya

RadWindowManager with RadWindow that has an UpdatePanel

In the past I've successfully used a single RadWindow on a page. It works fine.

Now I need to have one RadWindow appear on top of another RadWindow. Reading through Telerik's documentation I've learned that I need to introduce the RadWindowManager. I did so but encountered this error: http://www.telerik.com/support/kb/aspnet-ajax/window/cannot-unregister-updatepanel-with-id-updatepanelid-since-it-was-not-registered-with-the-scriptmanager.aspx

There is NO WAY I can get rid of the UpdatePanel in my RadWindow. It must stay.

So reading the 1st suggested workaround I tried doing this:

<telerik:RadWindowManager ID="rwManager" runat="server" /> <telerik:RadWindow ID="rwNewMuckpile" runat="server" Behaviors="Move" EnableShadow="true" VisibleStatusbar="false" VisibleTitlebar="false" AutoSize="true" Modal="true"> <ContentTemplate> <asp:UpdatePanel ID="UpdatePanel2" runat="server"> <ContentTemplate> <div class="dialogHeader"> Move Muck </div> . . . 

But it just produced another error: "Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'ctl00_ContentPlaceHolder1_Mucking_rwNewMuckpile' can't be added to the application."

So what should I do?

Spin buttons below NumericTextBox in IE

I am using v2012.1.411.35 and having an issue with the numerictextbox and spin buttons. I have the spin buttons turned on and no other attributes set other than skin.

<telerik:RadNumericTextBox ID="RadNumericTextBox1" ShowSpinButtons="true" runat="server" Skin="Web20"></telerik:RadNumericTextBox>

In IE (7,8,9), the spin buttons appear below the textbox no matter the width set on the control. Is there a css class that could have been overridden somewhere that could be affecting the control?

Any suggestions?

from version v.2010.3.1215.40 to v.2010.3.1317.40
and I've got two options:
v.2010.3.1317.40 [Download]

What do these options mean?

upgrade wizard tells me "no projects selected"

Using Telerk WebUI VSExtensions 2011.02.712.0 I cannot get the upgrade wizard to work to upgrade my web site.

I use VS2010 to open a web site, when I open my website I get the dialgo from the Telerik top menu that it has detected the project uses an old version of Telerik controls, asks if want to upgrade, I click "YES" at that point it tells me that no projects are selected and that i should "Please go back and select at least one project in order to continue the upgrade"

The same thing happens when I right-click the top level folder in the solution explorer, choose "Rad Controls for ASP.NET AJAX" and click Upgrade Wizard.

This is a .NET 2.0 web site.

Anyone else running into this?

Limit number of loaded Tree Nodes

Is there any way to limit the number of child nodes loaded in the tree videw when expanding a node ?
(we were thinking along the lines of a paged load of nodes. A given number of nodes is then loaded at each click from the user).

If the db have like 10000 nodes we want to limit the user to load like1000 nodes as initial pagesize. enabling the user to page through.

Is this possible ?, if so any samples ?

Best Regards
