Hi,

it seems, that UpdateDropPreviewLine is not working with DropPosition.Inside. DropPosition.After works fine, but I want to give the user a clue, if the drop would result in a new child node or a new sibling node. Is UpdateDropPreviewLine in principle limited to DropPosition.After and DropPosition.Before or is the problem in my code?

Best regards
Thomas

I am still in the process of evaluating the Telerik WPF package. Everything was OK with the Chart component until I found this problem.
 When loaded with plenty of data, the chart crashes with the following exception :

Hi,

How can I add additional controls for certain fields in a PropertyGrid? Similar to Visual Studio. See attached image. 

 ​

I am using Telerik WPF Controls 2014.2.729.40.

I have enabled the multi-rows selection in the radgridview by setting SelectionMode="Extended". 

<tk:RadGridView ... SelectionMode="Extended">

The user can select all or select multiple rows in the grid. However, if the user clicks out of the radgridview. The selected rows appear as unselected until the radgridview regains the focus back.

Step 1: The user selected multiple rows in radgridview.The rows looked SELECTED.

Step 2: The user clicked outside of radgridview. The rows looked UN-SELECTED.

Step 3: The user clicked back in radgridview. The rows selected before appeared as ​SELECTED.

I want the selected rows stay SELECTED visually all the time no matter Telerik RadGridView losts focus or not.

Please let me know if there is any ways to achieve my goal. Any help is appreciated.​

Thanks!

Is it possible to create a hierarchical tree list view from a flat list, much in the way you can with a TreeList ( http://docs.telerik.com/devtools/wpf/controls/radtreeview/how-to/bind-to-self-referencing-data.html ) ?

We have a data structure where the objects have the ids of their parents, and we would much rather bind to a flat list, than rebuild the hierarchy.

I had a look at the hierarchical grid view (http://docs.telerik.com/devtools/wpf/controls/radgridview/hierarchical-gridview/self-referencing-grid.html ), but that still seems to put children at the top level (as well as the child level).

I'm trying to disable property changed aggregation on all grids (the timer within it causes issues with Word when I host it in an add-in pane).

I've added a style as so:

And I get this error:

The property "IsPropertyChangedAggregationEnabled" is not a DependencyProperty. To be used in markup, non-attached properties must be exposed on the target type with an accessible instance property "IsPropertyChangedAggregationEnabled".

I think I can see why.  The registration of this dependency property seems to be wrong. It includes a trailing space:

Hello!

I have a problem with Layout in RadDiagram. While using this example after applying Layout() method to my diagram (Sample.jpg), arrangement of layers and connections between them became very strange. Examples of applying Tree-down and Tree-up layouts are in the files TreeDown.jpg and TreeUp.jpg respectively.

Is it possible to place layers applying Layout() method, according to their connection?  

Thank You!

Hi, II have a RadListBox with an attached DragDropBehavior and a custom itemTemplate:

Technically everything works as expected, apart of the fact that reordering elements via drag&drop is nearly impossible.

Replacing the TextBox with a TextBlock fixes the issue but, of course, is not a viable option: the "Name" property should be editable...

Any advice on this?
