Dear support.

Is it possible to have more than one sets of special slots shown simultaneously and in different colours?

Hi,

I use version 2015.1.225.40 of Telerik and the Office 2013 theme. In the popup of the AutoCompleteBox control, I implement a grouping logic in the popup so for each group, I use an expander to expand/collapse a group. When I click multiple time on the arrow to expand/collapse a group, my application raise an exception:

Hello,

it seems that the TextAlignment property of a column is no more taken into account in the Q2 2015 version, with the Office2013 theme.

I have a GridView with an ContextMenu to show/hide the columns. The ContextMenu opens always if I do a right-click in the rows or the header. Unfortunately I have some Controls in my Grid with its own ContextMenu which never opens.

Is there a safe way to add the ContextMenu for the HeaderRow?

I need the same functionality for a TreeList. 

Thanks

Hi all - me again :)

Been making some good progress with the backstage view, but have hit another snag. We have defined the backstage view content as a DataTemplate, which allows us to use caliburn micro to inject views into the backstage view based on the items source (a list of menu item view models).

I would like to be able to close the backstage view from within these views. Eg, clicking cancel on a form within the backstage should close the backstage view. Currently, only the root object can do so (via the BackstageOpen binding), but don't like the idea of propagating that expression down the chain.

Any suggestions ? Basically, I want to be able to bind a cancel button to something that closes the backstage view.

I have a RadGridView bound to a collection within my ViewModel. That RadGridView specifies a RowDetailsTemplate. The RowDetailsTemplate is another XAML file. From the RowDetailsTemplate XAML file I can bind to members of the collection type, but cannot bind to members of the original ViewModel.

How can this be achieved?

I've tried setting the DataContext of the particular control to the ViewModel I want to bind to, but this does not work. Any help would be greatly appreciated.

Hello,

how can I prevent the user can exit the form?

Hi there,

I searched and couldn't find an answer.  Is it possible to have the grid automatically scroll to the right while a column is being drug to the right, so the user doesn't have to drop it as far as they can, then scroll, and then drag and drop it again?  Thanks!
