And what error is it giving?

Solution 2

Dear Friend,

If VIewState("Test") is nothing, then this will error because there is no instantiated value to call an instance method.

If ViewState("Test") is string.empty, then this is a valid string value, but empty (not null though).

Then try to check this by

if (ViewState("Test").Equals("")) then

I hope this will help you out.

Thanks
