Hi,

What values have you given for Maximum value and Minimum Value of Range
Validator?

Try for this, Maximum Value=9 and MinimumValue=0

But, -0 = 0 and you have set the min =0. If you don't want zero, then set the min = 1. -0 is not negative and it is not positive, it is zero.

You could write a keypress event to only allow numbers in the textbox. You could even do it with Javascript if you don't want to do it server side.

Here's how we can accomplish this easily

Imports System.Text.RegularExpressions
 
Public Class BlahBlahBlah
 
        Private Sub NoNegativeZero() 
        Dim MyRE As New Regex("^[0-9]+$")
        Dim MyMatch As Match = MyRE.Match(TextBox1.Text)
        If MyMatch.Success = False Then
            MsgBox("I'm not cool with -0")
        End If
         End Sub
 
End Class
 

Hope this helps.
