You can do this with keyUp event handler and SuppressKeyPres s property of KeyEventArg like this:

Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
        If e.KeyValue < 48 Or e.KeyValue > 57 Then
            e.SuppressKeyPress = True
        End If
    End Sub

If you are using .NET 2.0, try using the MaskedTextBox control.

Hi there,

If you wanna apply server side validation for not allowing anything else then numbers use the acii code present in second solution but it is advised to use client side validation ie in your vb.net toolbar, use regular expression validator..for that validator in the properties window enter a regular expression.

Hope this help..
