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.

RadGridView with custom column cells, multiple item selection, and right menu click

Hello everyone!

I'm currently not sure how to implement a solution for this problem. I want a RadGridView which has the ability to select multiple items whether it's shift or ctrl clicks, but I once the items are selected, I want the user to be able to right click and make a selection in a menu. For instance, if a grid column is just a column to designate colors of each item, the user can select in the menu, change color and a window pops open and then they can select the color. Once the color is selected, then all the items that the user selected would be changed to that color. I understand I should use the RadContextMenu, but I'm not certain on how to use it with multiple selections.

Also, how can I make a custom column? For instance, I could just have a rectangle that would fill up and items cell and be a randomized color?

Thanks!
