Export nested radgrid to excel, errors with NullReferenceException

Sorry if this is a duplicate post. The other one did not show up in the list so I assume it got lost somehow.

telerik version: 2011.1.315.40
browser: FF
.net 4.0
VS 2010.

I have a radgrid with a nestedviewtemplate containing another radgrid. I am exporting to excel using a button in the radtoolbar control.
I am using advanced databinding for the master and child grids. The grids render the data with no errors. However, when exporting this error is raised: I have researched many posts on various binding techniques and am wondering if its related to that. I had the export working before when I used client side binding. Attached below are the aspx and .cs files. Please Help and Thanks in Advance.

how to remove dock from dockstate collection after dock.close event

I borrowed heavily from the dynamic portal sample http://demos.telerik.com/aspnet-ajax/dock/examples/myportal/defaultcs.aspx .. I noticed that when a user "deletes" a dock, dock.close() fires, and the dock remains in the dockstate collection (with Closed=true).

Is there a best practice or sample for how to remove it from the dockstate collection as well?

Treelist Horizontal Scroll bar

Hi

Is there way to enable an horizontal scroll bar on the tree list. I have a tree list with auto generated column. The columns at the end does not show up if it exceeds certain number. If I reduce the column width manually than I can see those missing columns.

Is there a way where I can have the screen scroll horizontally automatically.

Thanks
Shabbir

Scrolling Issue with Opera

I have a page with horizontal scrolling. The page has either one or two frozen columns along with an arbitrary number of other columns. The page renders fine in FF, IE, and Chrome. In Opera, however, I have a scrolling problem. When I scroll, half of the non-frozen columns stay in place. The other non-frozen columns get bunched up like a sock pushed down to the ankle. Is this a bug in Opera? Am I doing something wrong?

In fact, my RadScheduler is parametred like this :

<telerik:RadScheduler ID="RSPlanning" runat="server"

DataSourceID="ODSCalendar" Culture="fr-FR"

DataKeyField="IdCalendar"

DataEndField="DateFin"

DataStartField="DateDebut"

DataSubjectField="Commentaire"

SelectedView="MonthView"

ShowViewTabs="False"

OverflowBehavior="Expand"

And every thing is working well.

But, when RGPlanning_TimeSlotContextMenuItemClicking is fired, I can't ReBind my RadScheduler... Do you have an idea?

In This methode, in fact I change the categorie of each appointment of the week... That's why I would like to Rebind all my Appointements... (To see visualy the changes...)

Thank you to help me
