RadGrid NestedViewTemplate Generate - System.InvalidOperationException: Collection was modified; enumeration operation may not execute

Hello,

I'm encountering an exception using RadGrid's NestedViewTemplate feature.
If I set HierarchyDefaultExpanded="true" RadGrid, NestedViewTemplate is rendering correctly but all rows are expanded which is not very interesting. So i leave HierarchyDefaultExpanded to false so rows are initially collapsed when i expand a row following exception is raised

[System.InvalidOperationException: Collection was modified; enumeration operation may not execute.]

I have tested a lot of scenarios with no success. RadGrids are both initialized programmatically (ItemCommand, ItemCreated, PreRender, NeedDataSource for NHibernate list).

After testing, exception raise when system tries to render manual columns (GridDateTimeColumn, GridBoundColumn) as AutoGenerateColumns="False". If i remove manual columns, expand/collapse is working.

set dropdownlist value client side

Hi, we're using the FormDecorator and I notice on the front end the dropdownlist renders as a div with spans instead of a traditional html select list.

When I try to use jquery to set the selected value after the control renders it doesn't change. I'm guessing because this is technically not a select list anymore.

Is there any work around to this?

Hide Column in child hierarchy if no data

I was wondering how to go about hiding several column's in a child of a Hierarchical RadGrid if there is no data found for those columns. It would be quite nice to be able to do the same on the parent as well.

I've had a good search on the forums but can't find a good example to follow..

can anyone suggest a way to do this..

many thanks

TableLayoutCssFile & CssFiles.Add

Hi Telerik Team,

I created a RadEditor ( radEditor ) in my webpage. I set :

radEditor.TableLayoutCssFile = myCustimizedTableCssFile;
radEditor.CssFiles.Add ( myCustimizedCssFile );

In the editor iframe, it will automatic load myCustimizedTableCssFile first then load myCustimizedCssFile. Is there have way to switch them?

Thanks,

Editor

Is Teleric a Managed or UnManaged Object?

As per the Page life cycle in ASP.net, under the Unload event of Page Life cycle all the controls should be disposed. But it's not true when we have used FileStream Objects in the same class. We have to dispose it manually to manage memory.

Query - When using the teleric controls, is it necessary to dispose it manually or during the execution of Unload event, it's object will be disposed?

Query - Teleric control is Managed or Un-Managed?
