data access layer throws exception then edit form stayes in edit mode but populates the edit form controls with old values

I have radgrid that calles the objectdatasource which calls the data access (DA) to populate the radgrid.
Radgrid has edit form template to update and insert the records.

1. radgrid is open in edit form ..
2. User enters the NEW values and click the update button.
3. DA is called to update the database.
4. DA throws the exception that business logic rejected the update process ...
5. DA is automatically called to get the data again and keeps the radgrid in edit mode... and controls are populated with the original values this results in loss of NEW values entered by the user...

My understanding is that after step 4... DA should not be called again to populate the edit form with original values.. Rather it should retain the NEW values and give the user a chance to modify these to try again the update process....

My code radgrid1_ItemUpdated is keeping the radgrid open in edit form template but the NEW values are lost as radgrid goes back to the DA to get the original data. Where as this round trip to database is USELESS...

protected void radgrid1_ItemUpdated(object source, GridUpdatedEventArgs e)

{

if (e.Exception != null)

{

e.KeepInEditMode =

true;

e.ExceptionHandled =

true;

WHY radgrid goes to step 5.. How can i stop it...

Viewstate Bulkiness

I observe my pages are weighing more than 143 K of viewstate because of telerik controls (grid/tabstrip). Is there a way the telerik controls can work with ViewState disabled for the page? What is traded off in the process?

OccurrenceDelete not firing

My boss wants to do recurrence handling his way which is having an actual DB entry for each appointment. And they are being grouped by some common field in the DB. When those appointments are loaded I check for that field and if it's not 0 then I know that this is a recurrent appointment so in AppointmentDataBound event i do the following:

If row.Item(10) = 0 Then

e.Appointment.RecurrenceState = RecurrenceState.NotRecurring

Else

e.Appointment.RecurrenceState = RecurrenceState.Occurrence

End If

But when I click on the delete icon the OccurrenceDelete event does not fire. What should I do to fix it? Thanks

Moving items in Grid with buttons instead of drag and drop

Hi,

I have a requirement from our clients. They would like to have up and down buttons ( like you have in list box) to move items up and down in a Rad Grid. They don'T want to use drag and drop functionality already provided with the Rad Grid. Is there a way that I can achieve this with Grid?

Thanks

Cast conversion problem in Charts

Hi
currently i'm designing reports using Telerik Reporting in layered architecture.every method related to this report returns List collections.
But I'm using Datatables in reports,so that i encounterd this error ,
Unable to cast object of type 'System.Collections.Generic.List`1[LAEMIV3.Business.Entities._00001.User]' to type 'System.Data.DataTable'.
can u give me a sample for how to design a chart using grouping in telerik reporting.

private void groupHeaderSection1_ItemDataBinding(object sender, EventArgs e)
