[Solved] Rad Grid TemplateColums Validations

[waruni]

Hi,

In Rad grid Control, There are 3 Template Columns (Start time ,end time and Today ) and it has two Rad Time Picker control for      Edit Item Template and check box for Today column.

I'm using the master page as well.

<telerik:GridTemplateColumn HeaderText="Starttime" UniqueName="Starttime" >
            <EditItemTemplate>
                <telerik:RadTimePicker ID="rtpStartTime" runat="server">
                </telerik:RadTimePicker>
             </EditItemTemplate>
            <ItemTemplate>
                <asp:Label ID="lblStarttime" runat="server" Text='<%# Eval("StartTime","{0:t}") %>'></asp:Label>
            </ItemTemplate>
        </telerik:GridTemplateColumn>

         <telerik:GridTemplateColumn HeaderText="End time" UniqueName="EndTime">
            <EditItemTemplate>
                <telerik:RadTimePicker ID="rtpEndTime" runat="server"
                </telerik:RadTimePicker>
            </EditItemTemplate>
            <ItemTemplate>
                <asp:Label ID="lblEndTime" runat="server" Text='<%# Eval("EndTime", "{0:t}") %>'></asp:Label>
            </ItemTemplate>
 </telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Today" UniqueName="Today">
            <EditItemTemplate>
                <asp:CheckBox ID="CheckBox1"  runat="server">
            </asp:CheckBox>
            </EditItemTemplate>
            <ItemTemplate>
                <asp:CheckBox ID="CheckBox2"  runat="server" Checked='<%# Eval("Today") %>'>
            </asp:CheckBox>
            </ItemTemplate>
 </telerik:GridTemplateColumn>

I want to validate that end time value is greater than the start time when today check box was checked.

how to use the validation control, and how to show the error messages in validation summary?.

Can you plz tell me the way of doing this.because this is urgent.

thanks
