Answer 1

Dear Null and Character String cant Add by this way if you want to add numeric then you should do like this


TextBox3.Text = (Convert.ToDouble(Convert.ToString(textBox1.Text)) + Convert.ToDouble(Convert.ToString(textBox2.Text))).ToString();

in Text Change Event

it will convert zero if null exist



you can also chaeck by TextBox1.TextLenght  = 0  then zero value

Answer 2

Yes, It would raise error as you are trying to add "" (empty text) with your 2/3 texbox's values(integer).

Just initialize (default Text value) all your textboxes with 0 or 0.00

So, no matter how many inputs you give, it will not give you error.
