Vulpes · Answer

To make sure you don't get an error when the textbox is empty or doesn't contain a number I'd write the code like this. Zero will then be substituted for an invalid value: decimal a b c; Decimal.TryParse(textBox1.Text out a); Decimal.TryParse(textBox2.Text out b); c = a + b; label1.Text = c.ToString();

Srikanth Reddy · Answer

It Will WOrk protected void TextBox2_TextChanged(object sender EventArgs e) { int a = Convert.ToInt32(TextBox1.Text); int b = Convert.ToInt32(TextBox2.Text); label.text=(a+b).ToString(); }

Shweta Lodha · Answer

Writing above code on page load is not going to work as initially your text boxes are empty which will give you error while conversion. You need to write your code either on some button click or on textchanged event.

Srikanth Reddy · Answer

var a=convert.ToDecimal(textbox1.text) var b=convert.ToDecimal(textbox2.text)
