Dear All,

In my application there are three buttons 1,2 & 3 when I click on buttons 2 & 3 there is no error message. Then when I click button 1 and after that click on buttons 2 and/or 3 I get the following error message:

"Object reference not set to an instance of an object."

null reference exception was unhanded by user code

We need to see the code for the three button click event handlers.

Do you think the information you provided is sufficient for someone to undestand the issue?

The error might rather occur in Question.AddQuestionToDb(qs); or a function called from there.
Can you provide the stack trace, and the code of the function where the error finally occurs.

Solution 1

explain it clearly what exactly you are doing with three button.if u calling same event again again with this button may be you are getting the error for that

the meaning of error message is that simply you are forgetting the assign the value to the particullar varaible or method
