Hi,

You can use AJAX FilterTextBoxExtender to filter the characters entered in the textbox.

Here is the sample code for you

<asp:ScriptManager ID="SM1" runat="server"></asp:ScriptManager>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:TextBox ID="txtNumeric" runat="server"></asp:TextBox>
                <ajax:FilteredTextBoxExtender ID="FTBE_txtNumeric" runat="server" FilterType="Numbers" TargetControlID="txtNumeric"></ajax:FilteredTextBoxExtender>
                <br />
                <asp:TextBox ID="txtAlphabet" runat="server"></asp:TextBox>
                <ajax:FilteredTextBoxExtender ID="FTBE_txtAlphabet" runat="server" FilterType="UppercaseLetters,LowercaseLetters" TargetControlID="txtAlphabet"></ajax:FilteredTextBoxExtender>
            </ContentTemplate>
        </asp:UpdatePanel>
