    RadGrid for ASP .NET version

    RadControls for ASP .NET AJAX version

    3.0.3 and later

    2008.1.415 and later

    .NET version

    2.0 and later

    Visual Studio version

    2005 and later

    Programming language


    Browser support

    all supported by RadGrid for ASP .NET

    all browsers supported by RadControls for ASP .NET AJAX

    To enable grouping of a single column at a time:

    1. hook the GroupsChanging event of r.a.d.grid
    2. in the respective event handler determine where the current action is dropping column in the group panel
    3. if this is the case and the GroupByExpressions collection of the grid is not empty
      - cancel the default action
      - clear the GroupByExpression collection
      - add the current expression (hold by the e.Expression argument) to that collection
    4. rebind the grid calling its Rebind() method

    Hi Krefftc,

    Basically, the approach will be the same. The only difference would be that you will need to use NeedDataSource, instead of the AccessDataSource. The rest of the functionality is handled in the GroupsChanging event handler, as shown below:

    protected void RadGrid1_GroupsChanging(object source, GridGroupsChangingEventArgs e)  
            if (e.Action == GridGroupsChangingAction.Group)  
                if (RadGrid1.MasterTableView.GroupByExpressions.Count > 0)  
                    e.Canceled = true;  

    I hope this helps.

    Have a nice day,

    the telerik team
