Dear Telerik Gurus,
Good morning.
I would like to ask how can i possibly access the controls inside a RadTabControl and RadTabItem inside a RadDataForm
I am trying to access them with the code below:
If the control is outside the tabcontrol, I can successfully access the control, however if the controls are inside the tabs, i am getting the below error:
Sequence contains no elements
with the following details:
{System.InvalidOperationException: Sequence contains no elements
at System.Linq.Enumerable.First[TSource](IEnumerable`1 source)
at csis.Views.ContractList.tbl_contractsRadDataForm_Loaded(Object sender, RoutedEventArgs e)
at MS.Internal.CoreInvokeHandler.InvokeEventHandler(UInt32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)}
Can anyone point me out on how to fix my problem?
I am trying to access the controls in the tabcontrols in the loaded event of the form.
Thanks in advance.
