Ascii of backspace is 08.

but for calculator you need to trim from right.

Say your handler for the button backspace is

C#

Private void backSpace_Click(object sender, EventArgs e)
{
string str=textBox.Text;
int len;
len=str.Length;
textBox.Text="";

textBox.Text= str.Substring(0, len - 1)

}

The textBox is the textbox where the numbers appears in the calculator.
