Insert/edit mode and exceptions

I have a radgrid populated by the "OnNeedDataSource" event.
Radgrid has edits form template to update and insert records that call the "OnItemCommand" event.
This works fine while no exception is raised in update or insert methods but in the other case I have the following problem:
my code keeps the radgrid open in edit/insert mode and keeps also the new values inserted from the user but the commandbuttons don't call the ItemCommand anymore, at this point, clicking on the confirm button, it seems that it make just a simple postback erasing all the data in the textboxes.
Here it is an example of my code

    
            HTML  
        
            <telerik:RadGrid ID="grid_utenti" runat="server" AllowAutomaticInserts="false"   
        
            AllowAutomaticUpdates="false"   
        
            OnNeedDataSource="grid_utenti_NeedDataSource"   
        
            OnItemCommand="grid_utenti_ItemCommand">  
        
            CS  
        
            protected void grid_utenti_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)  
        
                    {  
        
                         grid_utenti.DataSource = call to a method that returns a dataset;            
        
                    }  
        
                    protected void grid_utenti_ItemCommand(object sender, GridCommandEventArgs e)  
        
                    {                         
        
                        if (e.CommandName == RadGrid.PerformInsertCommandName || e.CommandName == RadGrid.UpdateCommandName)  
        
                        {  
        
            try  
        
            {  
        
                           //call to method that insert/update  
        
                           }  
        
            catch(Exception exc)  
        
            {                      
        
                                e.Canceled = true;  
        
                    }

            }

Thank you

Cookieless Session

We're using a RadComboBox within a RadGrid with an ExternalCallBackPage. Everything was working fine until I implemented the following line in the Web.config:

<sessionState mode="InProc" cookieless="true" timeout="60"></sessionState>

This caused the URL to look like:

http://WebServer/OurApplicationName/(S(kvral4fk0tipgb55bv05sn55))/Default.aspx

This part is new:
(S(kvral4fk0tipgb55bv05sn55))/

The error is "RadComboBox: load on demand callback error", then:

If RadComboBox is not initially visible on your ASPX page, you may need to use streamers (the ExternallCallBackPage property)
Please, read our online documentation on this problem for details
http://www.telerik.com/help/radcombobox/v2%5FNET2/combo_externalcallbackpage.html

GridColumn looks odd on adding back a column

Hi,
   This post is related to the HeaderContextMenu online demo at http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextmenu/defaultcs.aspx . The Grid Column looks odd (row lines are missing) after performing the following steps.

      a) Goto http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextmenu/defaultcs.aspx
      b) Right click on the header of the table containing the Discount Column
      c) Using the Columns Chooser uncheck the Discount column
      d) Now expand the table with Orderid 10692
      e) Now using the Header Context menu column Chooser check the Discount column

RESULT:
     The Discount Column Looks odd without row lines as shown in the attached screenshot.

I would like to know how to make the Discount Column look similar to other columns without performing further steps.

Thanks
Satyaprakash J

Linq data source hierarchy in radGrid

Are there any examples of using a LINQ data source (or Linq2SQL in code) to create a hierarchy in a RadGrid? All the examples I have found use DataSets.

I have, for example, a User object that has Roles that are loaded with the Object. User.Roles returns a IEnumerable list of roles that that user belongs to.

Table Structure

User <- User Roles -> Roles

Thanks,

Brian
