And you think we can "check it" how? We don't have your forms or your data so what is it that you think we can check for you? Catch the exception that is being thrown, then fix it.

Well obviously there is a problem with your code and I have already told you what you need to do to find out what it is to fix it.

well now i am using this code for sum
Double sum1 = 0;
int rowIdx1 = dataGridView2.Rows.Count;
for (int i = 0; i < dataGridView2.Rows.Count; ++i)
{
sum1 = Double.Parse(dataGridView2.Rows[i].Cells[1].Value.ToString());
}
textBox14.Text = sum1.ToString();
but it's show nothing

And I already told you what you need to do to find and fix that too. The error that you are making is that you think we can see your screen, we can't. You are the one sitting in from of your screen with your code so you are the one that needs to figure it out. Learning how to debug your code is a very useful skill that you need to develop.

Solution 1

Check for each [FormName].Close() in your code and set a breakpoint on them. If they are being used when they should not be, the debugger will stop your code and show you exactly where.
