Public Class Form2 Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress Dim c As Integer c = Asc(e.KeyChar) If c = 8 Or c = 13 Then Exit Sub ElseIf c < 47 Or c > 57 Then e.Handled = True ErrorProvider1.SetError(TextBox1, "Invalid Number") Else e.Handled = False ErrorProvider1.SetError(TextBox1, "") End If End Sub End Class just create a user control and use it wherever u want

i did that too but every line is executing very well. At the end of lasat curly brace its giving error. i thought there is no error in the program. but i think the error i am getting is general error due to some settings. if anyone aware of this type of error then they may solve.

I traced the page. Its giving error after the "Begin Pre render" event.
