Create Start datetime - End datetime edit form

[Minh]

Hi,

I have a start datetime picker and an End datetime picker on my edit form. Please let me know a way to make the End datetime to always pick a datetime period that follows the start datetime

thanks,

Hello Minh,

Try the following markup to make a way that the EndTime always pick a date that follows the StartTime.
aspx:

<telerik:RadGrid ID="RadGrid1" runat="server"
.  .  .  .  .  .  .
 <MasterTableView  EditMode="EditForms">
  <Columns>
   <telerik:GridTemplateColumn>
     <EditItemTemplate>
        <telerik:RadDateTimePicker ID="txtBoxStartTime" runat="server">
        </telerik:RadDateTimePicker>
        <telerik:RadDateTimePicker ID="txtBoxEndTime" runat="server">
        </telerik:RadDateTimePicker>
          <asp:CompareValidator ID="StartEndTimeCompareValidator" runat="server" ControlToValidate="txtBoxEndTime"
          ControlToCompare="txtBoxStartTime" Type="Integer" Operator="GreaterThan" ErrorMessage="End time must be greater than start time" />
     </EditItemTemplate>
   </telerik:GridTemplateColumn>
  </Columns>
 </MasterTableView>
</telerik:RadGrid>

Thanks,
Shinu.
