Programatically adding pane to RadPaneGroup not working

I have a fairly simple scenario. In XAML, I've defined a RadDocking control. Within that control, I have a few RadSplitContainers. Within each of those contianers, I have a RadPaneGroup defined. That's the end of the xaml. In code, I dynamically add a pane to the RadPaneGroup that contains a usercontrol. I'm using the RadPaneGroup.AddItem method to do this. In the debugger, I see the new item, but when the window is rendered, there are no panes with content rendered. Is there something else I need to do in order to add panes programatically to pane groups?

Thanks in advance...

Force Validation On New Record Insert

In my gridview, I only allow unique combination of values in three of my columns. However, I want to allow the user to "clone" an existing row, and change the values in the other columns (those not constrained). How can I copy a new row, and initially show the new row to be in an invalid state? When I copy a new row now, it appears to be just another, valid row.

Note: The RowValidating event only seems to fire when I've completed an edit on that row. I need something similar, but outside the scope of editing.

Export multiple RadGridViews in RadPanes to Excel Files

Hi Telerik Team,

My application has multiple RadPanes, each RadPane has one or more RadGridView(s). I'm looking for a way to export all the RadGridViews on these RadPanes to an Excel files.
Currently, I'm only able to export the RadGridviews on the active RadPane which requires me to click on each RadPanes before exporting in order to export all the RadGridView. For example, I have 3 RadPanes, if I want to export all the RadGridViews in these RadPanes I have to click on these RadPanes one by one before exporting. If I don't do that I will only be able to export the GridViews on the active RadPane, but not all.

Is there a solution for this? Thank you.

Hi

Drop Preview Lines not visible on Radtreeview after upgrading to version 2011.3.1220.35. It worked fine on previous version.
I tried the setting IsDropPreviewLineEnabled="True" but that does not make the Drop Preview Lines visible. Any ideas on what may be causing this?

MenuItem FontSize

How can I increase the font size of a RadMenuItem when it's displayed as a child item (in a popup)? Simply setting the FontSize property doesn't seem to do it.

Copy Grid as an image

Hi,

We are successfully copying and pasting values from a grid to the clipboard and to Excel. However, we also wish to copy/paste the grid as an image. In other words, add both the tabular values and a bitmap copy of the image to the clipboard. And the user may paste special values or image.

How do we copy a grid as an image?

Thanks, TJ

Using RadMap with custom image source

Hi,
I am porting an application that uses the Silverlight Deepzoom functionality from Silverlight to WPF. Since WPF doesn't support this, I am evaluating using the the RadMap control to mimic that behavior.

I saw in this thread (http://www.telerik.com/community/forums/silverlight/map/radmap-as-zoom-pan-custom-image-navigation.aspx) that it is possible to do this with the Silverlight version of the RadMap control. Is it possible with the WPF control as well?

Can the WPF RadMap accept as source an image that was proccessed my the microsoft Deep Zoom composer?

Kind regards,
Mathieu
