I have an asp.net text box. I need restrict the application user to entering only positive integer values greater than Zero and less than or equal to 100. What is the best way to do this not using Java Script? But using Asp.net? If a regular expression is the best way, I am open to that, but I will need some help.

Honestly, Javascript would be best since it can be done on the client side but if you must use ASP.net, in the OnClick event of your submit button you can validate it by using the following:

Dim intValue As Integer

Try 
' Verify Integer
intInteger = CInt(textboxname.text.trim)
' Verify Between Values
If intInteger <0 OR intInteger > 100 Then
lblError.text = "Invalid Value. Must Be Between 1 and 100."
Exit Sub

' Other Processing Rules...
End If
Catch ex As Exception
lblError.text = "Invalid Integer
Exit Sub
End Try

Open in new window


lblError is just a label on your form to display the error message to the user.
