Hi,

Trying to see what can I change to improve performance for RadDiagram.

1- The goal is to show 2000+ hexagon.

2- Every hexagon has the same size, but it's color content might change. Every hexagon has a binding to a Viewmodel item.

3- Hexagons are grouped inside containers. The containers are pretty much transparent, except for its header.

4- There are no connectors and for now at least, users can't drag/delete/add items.

5- The diagram is contained inside a RadDocking and the docking is inside a regular WPF Tab.

When testing with 300 items there is a 4 second wait after the UI is loaded until the UI can be interacted with.

I am wondering, giving my scenario, what can I do to improve performance, giving that after loading the nodes don't change position/size.

Update NavigationPane when Diagram is hidden

Hi!

I have a diagram defined inside a docking window that can be hidden.

The NavigationPane works fine updating when there are changes to my diagram. However when I hide the Docking panel that contains the diagram (hiding the diagram), the navigation pane doesn't get updated anymore.

Is there a way to workaround that?

Thanks!

RadHyperlinkButton and Command

Hi,

I've assigned a command to a RadHyperlinkButton. The CanExecute handler is being invoked as expected, but clicking on the RadHyperlinkButton does not invoke the Executed handler. Is this by design? And if so, is it possible to force the execution upon click?

Best regards

Michael

Align the zeroes of the graphics axes

Is there any possibility of aligning the zeros of the axes, in a graph that contains more than one axis?

In the iamgen you can observe a graph with two axes where the zero of the axes is at different heights. The idea would be to adjust them to the same height. Thank you.

RadWindow.Prompt not showing

I'm trying to use RadPrompt (and RadAlert/RadConfirmation) in a WPF app using Prism. I have followed this guide: https://www.telerik.com/support/code-library/integrating-raddialogs-(confirm-alert-prompt)-with-prism's-interactionrequest-using-mvvm . At the point I raise the interaction request, I can see that the RadWindow.Prompt gets called (and it's Owner is set to the calling Window), but no prompt window shows. I can't interact with the owner window so that suggests the prompt does exist, it just doesn't appear to have any visual element. What might I be missing here?

Bug when using with IME

When using AutoCompleteBox with IME, the AutoCompleteBox may "steal" characters from the IME input.

For example, if there is an auto complete entry named "Hello", and we type "HA" in the AutoCompleteBox with an IME, the initial character "H" will be stolen by the AutoCompleteBox, leaving only "A".

The label and data entry fields are different from the template alignment of the sample.

I want DataForm to have a default alignment. However, the default alignment does not appear as sample as shown below. It is not known that the item can also be set from the attribute. I want to know how to change the settings.
