Sometimes stepping away for a Few Hours and doing someting fun and coming back Help. I found the Issue Althought it was strange

I was trying to cast a RADTextBox to a TextBox and it kept coming back as null rather than an invalid cast. But it works now YAY!!

[Jeff Reinhardt]

Not sure if this will help but I am reading some values from a grid after Insert using the following:

protected

 

void radgrdNotes_ItemInserted(object source, GridInsertedEventArgs e)
{
    

 

if

 

(e.Exception != null)

 

{

e.ExceptionHandled =

true;

 

e.KeepInInsertMode =

true;

 

DisplayMessage(

true, "Note cannot be inserted. Reason: " + e.Exception.Message);

 

}

 

else

 

 

 

 

{

 

DisplayMessage(

false, "Note inserted.");

 

 

RadTextBox EnteredBy = (RadTextBox)e.Item.FindControl("EnteredBy");

 

if (EnteredBy != null)

 

 

    string enteredBy = EnteredBy.Text;


This seems to work just fine for my scenario, hope it helps for yours.
