Invoke or BeginInvoke cannot be called on a control until the window handle has been created

Question

I am executing following code:

grid.Invoke(New MethodInvoker(AddressOf RefreshDataSource))

getting InvalidOperationException exception.

Message: Invoke or BeginInvoke cannot be called on a control until the window handle has been created.

Stack Trace:

   at System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous)
   at System.Windows.Forms.Control.Invoke(Delegate method, Object[] args)

It is inside a method that is getting invoked on occurrence of an event. — Brij, Apr 19 '13 at 19:17

Change the call from the load event to form.shown event to ensure that the control has been created first

if (!this.IsHandleCreated)
    this.CreateControl();

this.Invoke((MethodInvoker)delegate
    {
       //do so      
    });

Add this before you call the invoke method while (!this.IsHandleCreated) System.Threading.Thread.Sleep(100)
