[RESOLVED] Numeric Textbox with "backspace"

Im using

Code:

---

Private Sub NumericKeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        Dim allowedChars As String = "0123456789"

        If allowedChars.IndexOf(e.KeyChar) = -1 Then
            e.Handled = True
        End If

    End Sub

---

and it wont let me use backspace. How would I make it so I can use backspace?

Take a look at the list of characters you've allowed ... and be aware that the backspace is simply another character.

What would be the Backspace though?

Forget testing against an array:

vb.net Code:

e.Handled = Not Char.IsDigit(e.KeyChar) AndAlso Not Char.IsControl(e.KeyChar)

IsControl accounts for baskspace, delete and others.
