Restrict user from entering special Characters in TextBox using JavaScript

Hi Neda,

If you want the User cant enter then

    <div>
        <Ajax:ToolkitScriptManager runat="server"></Ajax:ToolkitScriptManager>
        <asp:TextBox ID="txtRestrictSPChar" runat="server" />
        <Ajax:FilteredTextBoxExtender TargetControlID="txtRestrictSPChar" runat="server" FilterType="LowercaseLetters,UppercaseLetters,Numbers" >
        </Ajax:FilteredTextBoxExtender>
    </div>

This is the best and simple solution as well,

Thanks and Regards,
