Hello,

I'm using a RagGrid on a dynamically loaded UserControl. To keep row selected after postback I followed this: 
http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-on-sorting.html

The selected state on the server-side is succesfully set only client-side the record is not selected. When I check the select-item on the OnGridCreated event the count of selected-items is zero.

Can someone help me with this.

Regards,

TIA

Hello,
I have a textbox which is in invisible mode. I am making it visible on code behind.

RadTooltip is not working for that textbox. Is it because of the textbox is invisible initially ?

If so, how can I solve this ?

I am using RadScheduler to bind to Exchange server via Exchange Web Services. The idea is to pull out appointments from different mailboxes on Exchange and display them in the scheduler. I've managed to accomplish this by putting all appointments into a generic list and use that list as a DataSource for RadScheduler. This works like a charm. I need to be able to group these appointments by mailbox (e-mail address of the owner of that appointment). First, I tried to display appointment owner as a resource. There were no way I could accomplish this. Then, it came to my mind that I could display appointment owner as a Custom Attribute.
My question is, how can I programmatically insert Custom Attribute value while appointments are binding?

I have a RadGrid that is currently configured for paging and grouping...  the grouping will display group footers with aggregate=sum for a data column.

Question

After the data is bound, I would like to replace the pre-existing total values in the GridGroupFooterItems with my own custom values.

More importantly, before I devise my custom values, I would like to determine the group by expression that is associated to that particular GridGroupFooterItem (i.e. GroupByExpression columnname = x; column value = x, and aggregate columnname=x, and aggregate=x).  How can I find this information?

I downloaded version Q1 2010 SP1 Released 2010/04/15 and followed the installation instructions and received no errors.  I am using Windows 7 and Visual Studio 2008.
1) Created new project (RadControls Web Application)
- Telerik.Web.UI Assembly:  v.2010.1.415.35 [Installation Folder] [Trial]
2) Opened Default.aspx
- Switched to design mode
- Click on the Toolbox => There is no RadControls tab
Other tabs exist with controls:
Standard, Data, Validation, Navigation, Login, WebParts, AJAX Extensions, Reporting, HTML, Ajax Controls Toolkit and General (only tab with no controls)

Tried creating another project as an ASP.NET Web Application, same result.  No RadControls tab.

Any suggestions?
