Solution 1

Do validation for all the controls before saving.

So how do you relate that from the question???

I mean check all the controls are not empty before saving.

Solution 2

Try this to check if TextBox1 or TextBox2 are empty . If there are not save them.

 if ((String.IsNullOrEmpty(TextBox1.Text)) || (TextBox1.Text == "0")||(String.IsNullOrEmpty(TextBox2.Text)) || (TextBox2.Text == "0")|| etc...)
            {
                string Msg = "<script>alert('The textbox cannot be empty or zero!');</script>";
                ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "alert", Msg, false);
            }
            else
{
//here put your code
}
            {

As the OP said it is windows forms. Why not use the MessageBox instead?

Diana Tsax 24-Sep-13 6:48am
