Hi,

First of all, thank you for your beautiful controls, they are amazing.

I am new to telerik, and I want to export some controls into a PNG, PDF, and also print them.

I found some samples in your demos but they take a control (for example chart), and put it in a PNG, but what I need is to take all controls (a few charts, pies, grids, etc) and put all of them into one PNG.

Can anyone help me?
Thanks in advance, :)

Hi.
I'm currently evaluating Telerik controls, and I am having an issue with RadWindow. A key scenario is to observer how our dialogues display when the DPI is set at its extreme.

My RadWindow has SizeToContent set to true, and IsRestricted set to true.
It's a tall dialog, and my assumption was, when the display is set to a high DPI (200% in Windows 8), the dialog will shrink to cover the range from top of the screen, to top of the taskbar (at which point the scroll bars would activate).

However, instead, part of the title and the bottom part of the dialogue are either offscreen, or obscured by the task bad.

I've attached a screenshot detailing the issue (I've blurred parts of the dialog intentionally).

In an effort to address the customization issue of the QAT, I attempted to add a contextmenu for the RadRibbonButtons. However, from what I can tell, the ContextMenu has to be of type Windows.System.Controls.ContextMenu, which doesn't get themed correctly. 

Is there a way to use a contextmenu that picks up the correct theme/style being applied to the rest of the Telerik controls?

Cheers

I have a custom set of fields in a document and am using UpdateAllFields() when I want to render a completed document. I notice from the documentation that this is deprecated. What should I be using instead?

Thanks,
John

Hey,

The filter button in the column header still showing, any idea how to hide it?
I'm using the following code:

I have an expensive operation to determine if there are children for a node so I am determining if there are children asynchronously.  

I have simulated LoadOnDemand with the TreeListView using a view model with a background worker.  When the worker completes it's work it fires OnPropertyChanged for the collection and the tree then shows the expander.

Is there a way to show an animation in place of where the expander normally resides?  I would like it to be similar to how the TreeView loading animation displays when used with IsLoadOnDemandEnabled.  Right now my tree nodes show no expander until after the async call is complete and it is confusing to end users.

Thanks
