Examples

The following code example uses the Remove method to delete a child control from the myButton server control. First the code uses the Contains method to determine whether the myChildControl is contained in the ControlCollection object, and, if it is, removes it.

// Use the Contains method to check whether
// a child control exists, and if it does,
// use the Remove method to delete it.        
if (myButton.Controls.Contains(myChildControl))
{
   myButton.Controls.Remove(myChildControl);
   msgRemove.Text = "You removed myLiteralControl.";
}
else msgRemove.Text="The control to remove does not exist." ;

' Use the Contains method to check whether
' a child control exists, and if it does,
' use the Remove method to delete it.        
If myButton.Controls.Contains(myChildControl)
   myButton.Controls.Remove(myChildControl)
   msgRemove.Text = "You removed myLiteralControl."
Else
   msgRemove.Text="The control to remove does not exist." 
End If

Remarks

To remove a control from an index location, use the RemoveAt method.
