Hi there,

I have a RadGridView with a GroupHeaderTemplate.  Every time any group is expanded / collapsed or a new column grouping is added or removed, all group header controls (as defined in the GroupHeaderTemplate) are unloaded and new ones are created.  Is it possible to stop this behaviour so that all group header controls are not recreated on every action?

Thanks

Hello,

after I load the tree I want to expand all items, then call BringPathIntoView(). This does not work. If I do not call ExpandAll(), BringPathIntoView will select the correct item. My requirement is that I expand the whole tree and select a specific item based on certain rules. Here's my code:

 radTreeView.ItemsSource = _radTreeViewItems;

radTreeView.ExpandAll();

radTreeView.BringPathIntoView("something\\somethingChild");

The "something\\somethingChild" path is an item near the bottom of a large tree and it does not scroll down. Is there a way to wait for the ExpandAll() method to finish, then call BringPathIntoView?

Thanks,

Scott

I am using the diagram view in MVVM mode and I have built my test app starting from the MVVM SDK sample and the Class Diagram demo.

I can create shapes and connections programmatically. Connections created programmatically can be edited. I am using "gliding" connectors. My test app is able to create new shapes by dragging/dropping shapes from the toolbox. However, I cant create new connections interactively. When I click a shape, the center point of the shape shows up, when mousing over it, it gets highlighted and the tooltip "Connect" does appear. I am getting ConnectorManipulationStarted event. When dragging the mouse away no connector is showing up, and no Completed event ever fires. I have made sure that every editing related property is enabled on shapes, connectors and diagram style, but nothing...

Any idea ?

Thanks !

Hi!

We are implementing a patient history where we want to plot some medical data values with a bar series (vertical) and line series, medication with bars (horizontal) and interventions (e.g. operations) with vertical lines that have a symbol. I made an annotated drawing (attached) so the use case is clear.

The vertical bar and line graphs are easily done with the RadCartesianChart. However, what I'm missing is a chart, that can display the treatments (Placebo Forte et al.) and the treatments (syringe and scalpel). It's important for them to align with the chart, since they share the same timeline.

What would you suggest for this use case?

Thanks in advance and best regards,

And Xaml

That work at Design time, I cant see the view, but if I add this custom page to WizardPages collection  from RadWizard nothing happend.

What am I doing wrong?

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 :
