Here is my aspx code:
Here is my .cs code:

Any ideas?

I am working with grid and i would like to display a Name column as:
Smith, Joe
and sort by last name as well.
I have tried a GridTemplateColumn, which gives me the proper display, but I can't sort.
I have tried GridBoundColumn, which gives me the sort functionality, but i have to display the data in two columns.
How can i use GridBoundColumn to display Datafield="Contact.Lastname, Contact.Firstname"?

I am trying to create a wizard-like interface much like the demo on the Tabs page. I have been able to get tab navigation working fine as well as loading each individual user control. Utilizing the RadAjaxManagerProxy I have been able to get all AJAX working. The only issue I still have is getting my user control to have a button that enables the next tab (located on the main page) and make it visible (along with its associated PageView).
Any suggestions? I've been beating my head against the wall for the better part of four hours now and am at a complete loss.

Hi,
I have a RadGrid which is allowing client-side collapsing/expanding along with client-side row selecting. I am using the Gray theme and have the grid set up as a self referencing hierarchical grid.
With that said my problem is that not all my rows need the collapse/expand icon to appear and your default functionality is to hide the icon. The problem is that when a cell is empty in IE it doesn't draw border lines around it so the end result is funny looking if I select that table row.
The CSS you have set by default with the Gray theme has the border color set as white and if its a selected row the border is then black. However, the empty cell will still just display a white border so you end up with a very inconsistent look.
Is there any way to tell the grid to put in an   instead of nothing into this cell when the image is not required so that the top/bottom border correctly displays around the cell?
Thanks

Hi everyone,
Is there any way to use the Rad Grid in order to get the same functionality as showed at http://blogs.msdn.com/performancepoint/archive/2007/07/20/strategy-maps-in-performancepoint-server.aspx ? Notice that Actual and Target headers are fixed and the master-detail behavior is only applied in the first column.
Thanks in advance.

Hi, I have been trying to figure out the best way to use a radwindow to edit a grid record (manually) and then refresh the grid only when an update has been made. I have searched and found examples that do not use master pages and these work fine. However, because I am using a master page it doesn't seem to work. I have tried various things that I found throughout the forum and can't get it to work. The last post I saw said to try and find the ajax manager on the master page - but I don't know how to tie this into the other parts. Is it possible to get a full example of how to use a grid in master pages and radwindow for editing while using ajax manager? Thanks in advance.

Hello
'm doing some testing with panelbar and I find this problem.
I have a panelbar "deputy code", like this example
http://demos.telerik.com/aspnet/prometheus/Panelbar/Examples/ApplicationScenarios/AccessingNestedControls/DefaultVB.aspx
where the first page I have to validate a code into a textbox, and verify that the information typed in there is true, otherwise we can show an error report on a label.
as I do, to the extent possible without a postback but using ajax on the same page.

I access the controls like this in the same example, but not as assigning the control "lbl_error" some value and you can update and display executed after the procedure.
thanks
