Hi,
here is the code-

C#

protected override void OnKeyPress(KeyPressEventArgs e)

{

if ((!char.IsDigit(e.KeyChar)) && (e.KeyChar != 8))

    e.Handled = true;

}

Solution 2

As you have only tagges your question to C#, I am not sure if you want to do this in Windows or Web App.
In any case, I would use the regular expressions.
For start, you can use the following RegEx.

C#

Regex regex = new Regex("^[0-9]+$");

Read more about the Regex [^]class on MSDN.
