i would personally use a built in validator control such as the RegularExpresssionValidator. Example if your textbox has ID "TextBox1":

<asp:RegularExpressionValidator id="regVal1"
                   ControlToValidate="TextBox1"
                   ValidationExpression="\d+"
                   Display="Static"
                   EnableClientScript="true"
                   ErrorMessage="Please enter a numeric value."
                   runat="server"/>

Open in new window


you may also want to look at the range validator if you want to restrict the input further:
