ASP.Net 2.0 VS2005 NullReference Error

Asked by ttinsley in .Net Editors & IDEs, Visual Basic Programming, .NET

I have a button in each line of my gridview which fires a stored procedure but  want to disable the button if two of the values returned on that same line are equal. No matter what I try I keep getting the same error message during runtime stating that "btn.text is Null and that I should use new to create a new instance of that object.

I used the same basic code on a checkbox in another page and it works beutifully, What am I missing?Start Free Trial
