    i have grid

    <telerik:GridTemplateColumn DataField="Mark" DataType="System.Int16" FilterControlAltText="Filter Mark column" HeaderText="Mark" SortExpression="Mark" UniqueName="Mark">
                                    <asp:TextBox ID="txtMark" runat="server" Text='<%# Bind("Mark") %>' Width="50px" AutoPostBack="True" Font-Names="Arial" Font-Size="Small"></asp:TextBox>
                                <HeaderStyle Font-Names="Arial" Font-Size="Small" />
                                <ItemStyle Font-Names="Arial" Font-Size="Small" />

     and  a Radtextbox outside the grid

    i would like to compare the value from the ItemTeplate to the one in the RadTextbox and if the itemplate value is greater than the RadTextbox throw a msg.

    Can anyone help?

    Generally, if you will use numeric values in these inputs, it is better that you use RadNumericTextBoxes. Then, you can use the client-side or server-side validation functions of the asp:CustomValidator to achieve this requirement:

    I hope this will prove helpful.
