Badly worded, most generic error going, txtspk.

There's no way we can help you unless you give us more information. What platform? Winforms? Asp.Net? WPF? Silverlight? Show us the code where the exception is happening.
   
This is one of the most commonly know errors (if not the most).

It means you have used the mtldatagridcontrol before initiating it.

Check your code, debug it if needed. Somewhere you are using the mtldatagridcontrol while it is null.
