objDyn is probably null. What is it? A control? Some custom class? Where do you initialize it?

This error happens when you try to use a property or call a method of an object that is null. More details: here[^]

A simple use of Visual studio DEBUGGER can tell you the object because of which it is happening. Just look at the stack trace and put a debugger on that line. Check the objects of that line and see if any one is null and you are trying to use that objects property. Handle the same.

Above, looks like objDyn is NULL or one of the parameters passed assuming error is not raised in GenerateTabControls method.

What do you mean by 'coming null', have not these implemented/defined/written by you?

As Bernhard said, out params can be null. Step through and check the line where it bombs. Use F11.

hi sandeep
dynDiv is coming null.i put breakpoint and checkd..

C'mon, those are the OUT parameters - they can be null when you call the function. In case you get the error really exactly in the line shown, objDyn is null. Where is that instatiated?
But I am not sure if you have checked that the error was not raised in GenerateTabControls function...

Thanks for correcting me. Yes, only objDyn looks potential culprit. (Assuming error is not raised in the method!)
