Hi

I have a GridView with 3 column, Id, Name and Quantity
I have created a group using the Name column.
I have a GroupEvaluate that calculates the total quantity in a group and displays it on the group header.

My gridView is bound to a DataSource (AccountRowBindingSource) containing and Generic List of Linq2SQL objects (called RowsToAdd).
My first problem: When I add rows to my RowsToAdd the GroupSummaryEvaluate event is not fired so my group header is not recalculated.
However, If I expand the group, I can see all added rows.

To force the GroupEvaluate event to trigger I added a ResetBinding call, like this

AccountRowBindingSource.DataSource = RowsToAdd

AccountRowBindingSource.ResetBindings(False)

After the change, the GroupSummaryEvaluate event is fired and the correct summary is displayed in the header.
BUT..
Now Groups in the RadGrid randomly expands. I can see that its the ResetBindings that is making this happen.
So, Why is the groups expanding even though I have set the AutoExpandGroups = false?

Regards
Per

Button Theme Name

I created a VB.NET 2010 Windows Form application project, added a Windows Form, then added a RadButton to the form. I set the Theme Name to OfficeGlass through the Smart Tag. In design view, the button is rounded with a dark blue gradient. It looks fine in design view, but when I run my application, the button goes back to the default theme style (light blue).

Why is the button theme changing at run-time?

Thanks,
Chris

Column not set to scroll

Is there a property on the radgrid that will stop a column from being part of the horizantal scroll. For eg:- When the grid scrolls horizantally, I do not want the left most column to scroll as I want it to remain on the screen. Similarly, on a vertical scroll, I do not want the column headers to disappear from the screen.

Thanks
Deepak

Selecting a gridview row not in current view

When I set the CurrentRow on a row that is visible, the row is selected correctly. However, when I set the CurrentRow on the Grid and it is not visible in the current scroll area of the Grid, it doesn't scroll to the CurrentRow. And when you click the scrollbar, it automatically scrolls, but the wrong row is selected (the index always seems to be +1).

Example:

grdAwesome.MasterGridViewInfo.CurrentRow = grdAwesome.Rows[3];

works as expected, but

grdAwesome.MasterGridViewInfo.CurrentRow = grdAwesome.Rows[69];

doesn't work, as detailed above.

AppointmentMappingInfo issue

I'm having a problem getting the mappings to work out. The dates and text items (subject, description, etc) seem to work fine, however id fields do not, nor do any of the boolean values (visible, all_day, etc.) I know the field names are correct. Oracle does not have a boolean field type, so I can return a number or a string. Any ideas?
A condensed version of the code is:

daTemp.Fill(dtAppts)
Dim appointmentMappingInfo As New Telerik.WinControls.UI.AppointmentMappingInfo()
appointmentMappingInfo.Start = "APPT_START" ' One of the mappings
appointmentMappingInfo.BackgroundId = "BACKGROUND_ID" ' One of the mappings
SchedulerBindingDataSource1.EventProvider.Mapping = appointmentMappingInfo
SchedulerBindingDataSource1.EventProvider.DataSource = dtAppts
RadScheduler1.DataSource = SchedulerBindingDataSource1

Later
