我这样做已经有一段时间了，对我来说真的很好。

<telerik:GridTemplateColumn HeaderText="Depatment Type" UniqueName="DEPT_ID">
    <ItemTemplate>
        <asp:Label runat="server" ID="lblDeptName"
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadDropDownList runat="server" ID="comboDepts"
            DataSourceID="SqlDSDeptType"
            DataTextField="DEPT_NAME" DataValueField="DEPT_ID">
        </telerik:RadDropDownList>
        <asp:RequiredFieldValidator ID="rfvcomboDepts" runat="server"
            Display="Dynamic" CssClass="validationClass"
            ValidationGroup="grvgName"
            ControlToValidate="comboDepts"
            ErrorMessage="Department cannot be empty"></asp:RequiredFieldValidator>
    </EditItemTemplate>
    <InsertItemTemplate>
        <telerik:RadDropDownList runat="server" ID="comboDepts"
            DataSourceID="SqlDSDeptType"
            DataTextField="DEPT_NAME" DataValueField="DEPT_ID">
        </telerik:RadDropDownList>
        <asp:RequiredFieldValidator ID="rfvcomboDepts" runat="server"
            Display="Dynamic" CssClass="validationClass"
            ValidationGroup="grvgName"
            ControlToValidate="comboDepts"
            ErrorMessage="Department cannot be empty"></asp:RequiredFieldValidator>
    </InsertItemTemplate>
</telerik:GridTemplateColumn>

CSS

.validationClass {
    background-color: #FFCCCC;
    color: black;
    font-weight: bold;
}
