Hello,

I want to know if there is any way I can dynamically add a Detail Table between a Rad Grid and another Detail Table.
The structure would be the following:

Before addition:
<RadGrid>
<DetailTable ID="1">
</DetailTable>
</RadGrid>

After addition:
<RadGrid>
<DetailTable ID="2">
<DetailTable ID="1">
</DetailTable>
</DetailTable>
</RadGrid>

The Rad Grid and the detail tables feed from their own objectdatasource.

Thanks in advance.

hi 

i would keep the list of files after a postback like do the postbacktrigger property but i need it for validation purpose and so the postback to validate is the same than for upload.

i mean i have a single button to save my form and upload the file in server code i validate my form if there is a problem. i need to show again the form with information about the validation if no problem i save everything.

if i use the postbacktriggers property i don't get the upload event and i absolutely need it.

so i'm looking for away to give or keep the list in client side.

hope it was clear enough :-)

thank you 

Hello all,

I have encountered a problem while using the GroupFooterTemplate in RadGrid. I have implemented a RadGrid using GroupFooterTemplate according the documentation that I have found at your web site. Here is the link to the documentation: 
Group Header and Footer Templates

In the GroupFooterTemplate, I used several <td></td> together with labels to show the footer items. I have to use GroupFooterTemplate because a checkbox must be displayed in one of the footer columns.

The issue occured, when I used Aggregate="Custom" as follows
<telerik:GridBoundColumn UniqueName="OrderNo" DataField="OrderNo" HeaderText="Order No." Aggregate="Custom" />

The error message that I got is as follows:

An entry with the same key already exists.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: An entry with the same key already exists.

If I used Aggregate="Sum" or Aggregate="Count" instead of Aggregate="Custom" , the web application could run without error. Could you please tell me how to use aggregate custom correctly while using the GroupFooterTemplate?

Many thanks in advance!

Can somebody let me know how to fix this?

Hi,
When I attempt to delete the exception appointment of a recurrent series, I get the following exception:

System.InvalidOperationException: Cannot locate the parent of appointment with ID = '135'. Ensure that the parent appointment with ID = '36' exists and is loaded.
   at Telerik.Web.UI.Scheduling.AppointmentController.DeleteAppointment(Appointment appointmentToDelete, Boolean deleteSeries)
   at Telerik.Web.UI.RadScheduler.DeleteAppointment(Appointment appointmentToDelete)
   at Telerik.Web.UI.RadScheduler.ProcessPostBackCommand(SchedulerPostBackEvent postBack)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
   at Telerik.Web.UI.Scheduling.AppointmentController.DeleteAppointment(Appointment appointmentToDelete, Boolean deleteSeries)
   at Telerik.Web.UI.RadScheduler.DeleteAppointment(Appointment appointmentToDelete)
   at Telerik.Web.UI.RadScheduler.ProcessPostBackCommand(SchedulerPostBackEvent postBack)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I'm binding the scheduler to the list of objects I get from the DB in page load event. Deleting series or a single appointment works fine. Resizing, moving, editing appointments (including exception appointments) also work fine.

Could you point me to the correct direction to resolve this issue?

Cheers

Hi,
How to allow only C and D letters to be written int the third column of the radGridView. And prevent the user to type any other letters or characters??

Thankfully Yours.

Hi,

I have a (RadChart) pie chart and for some reason even though the 1 (and only) series item is showing 100% I get this unwanted line that makes it appear as though there is a another miniscule series item (segment) - can anyone tell me how to get rid of this line if at all possible - 100% should show as just a complete circle with no other pie segments.  Please refer to attached file.
