Hi,
I'm creating a GroupBy expression dynamically based on user input:

RadGrid1.MasterTableView.GroupByExpressions.Add(txtUserInput.Text);

Occasionally the user gets this wrong which causes an error.
I simply want to catch this error in a try/catch block and handle it, but I'm not sure where to put the try/catch.
Any help would be appreciated.
Thanks,
Nick

Hi.
I am migrating a former asp:grid, and since some features must remain the same (or as close to it as possible), the style of the GroupHeader should be similar to the former.
I need to find a way to change de color and size of the text of the GroupHeader:

Is there any avaiable property to perform such a customization? And if there's none, can I do it by changing the CSS (even if it means creating a custom grid css file)?

Many thanks in advance.

is there a way to not highlight the text in a grid when the user selects or drags with their mouse in a grid?  I've attached a screen shot of what it is doing currently.  We have other grids on our site that don't allow this behavior but I cannot figure out how that is possible.

Thanks,

Jon

I'm struggling to get IIS 7 to play nice with Telerik.

I get the following exception when I try to run an .aspx file.  I've migrated the config file using appcmd and adding the WebResouce.axd to both httpHandlers and handlers has not caused the problem to go away.  I'm inclined to think at this point though that the bug is with Telerik since I've seen other posts for third party component bugs cause a general complaint about WebResource.axd not being registgered.

I've gone through the troubleshooting page here on this site for configuration problems:  Please do NOT post this.  I've followed it, but It doesn't address my issue.

Any help would be appreciated. 

I'm using Telerik 2009.2.701.35 on a Windows 2008 R2 box running IIS 7.  The Telerik handlers are all appropriately mapped according to the console manager.

[InvalidOperationException: The WebResource.axd handler must be registered in the configuration to process this request.

I am looking to have a RadWindow open any URL I throw at it, but I am getting the following error:

BC30456: 'OpenRadWindow' is not a member of {page name}

It seems like it should be pretty simple, I must be missing something here...
