I would suggest you to use Regex[^] - Regex.IsMatch Method[^].

For further infromation, please, see:
Regular Expression Language - Quick Reference[^]

C#

<asp:textbox id="VisitorContacttxt" runat="server" cssclass="TextBox" maxlength="10" xmlns:asp="#unknown"></asp:textbox>
<asp:filteredtextboxextender id="VisitorContacttxt_FilteredTextBoxExtender" runat="server" xmlns:asp="#unknown">
 FilterMode="ValidChars" FilterType="Numbers" TargetControlID="VisitorContacttxt">
</asp:filteredtextboxextender>

Use filteredtextboxextender for enter number or symbol
