I have a RadCartesianChart and want to register for ContextMenuOpening. When I do it in XAML my event handler gets called. If I do in code (e.g. MainWindow_Loaded: Chart.ContextMenuOpening += Chart_ContextMenuOpening) it is not called.

I got a small repro too.

Here i have mentioned implementation of code. i created a custom control 'VSRadCartesianChart' and implemented some dependency control in  it and generate the X,Y axis and line series are dynamically.

i applied Zoom&Par bar visible to both axis and applied style that that it only visible when zoom & par when applied.(other wise in normal case, it does it show).

Also , I have implemented 'CartesianGrid' in it and applied Y axis line visibility.


problem which are facing:
1. setting which applied in cartesian grid is not shown. it doesn't apply any style in it. (see the attached image)
2. Y-axis zoombar is not shown. 
3. TargetType="chartView:PanZoomBar" style setting is not applied (controlling the visiblity of panzoombar based in property in viewmodel)


could you please give your feedback. it is urgent requirement.

Hi,

i have a performance problem with "Special Slots" in "schedule view". In my case I have n Groups, created dynamically out of a database. To see a special slot on grouping, I have to create each special slot for each group! In my case I have 960 Slots. Now the performance is not good on changing to moth view and on loading the application.

Is it possible to load the Slot once and use it for each group?

Thanks
Best Regards

Hi,

I need a "red line" that symbolise where my draged row will insert. The "Before / After" tooltip is hard to read in a grid with lots of rows/cells.

Any good C# examples for this?

Scenario:  I have a RadGridView with "Click here to add new item" enabled.

If I click on a row and then hit 'Enter', the selection navigates to the next row as expected.

If I click on "Click here to add new item" then a new row is created and focus is given to the first cell, as expected.  If I enter some data and press 'Enter' the data is committed but then it appears that the keyboard event is passed along to the parent control.  In my case, it dismisses the dialog.

Hi, I'm using editable GridView cells. I see that when I multi select several GridView rows from the top to bottom direction, the CurrentItem foucs moves to the bottommost cell and when I directly start to type something, the bottommost cell is edited. What I want to do is when I select cells from the top to bottom direction and start editing, the topmost cell gets the CurrentItem focus and starts to be edited. I tried to solve this by setting the CurrentItem property, but it was readonly. Is there any way I can acheive this? (I have to multi select cells first for some reasons, not only just editing cells!)

We have a single Property grid with around 83 properties. When the item on the property grid changes, it takes almost 400 ms to just set the new item to the property grid. 

I tried a test application and saw that with the number of proeprties increasing, the performance of the property grid gradually deteriorates.
Attached is a screenshot of the performance profile taken. Please help analyze and suggest how this can be improved. 

Please note: IsVirtualizing and EnableEditorCaching are enabled.

I'm hosting an EDrawSoft OfficeOCX in a WindowsFormsHost. (MVVM, C#, .Net 4.0) The control fills a tab in a tab control in a Telerik RadDocPanel.

Everything is working very well, until someone tries to open a damaged Office document which throws an error and seems to corrupt the OfficeOCX control.

I've found that re-initializeing the OfficeOCX control gets it working again, except that the WindowsFormsHost no longer fills the tab. Simply resizing the application fixes it up again.

I've tried calling Refresh on the OfficeOCX control which didn't work, but it's probably not the control that needs to be refreshed.

The control is being manipulated in a PropertyChangedCallback for a dependency property. MSDN suggests calling WindowsFormsHost.InvalidateVisual() but that didn't work either.

My next attempt will be to try to call a method on the Telerik RadDockPanel to force the repaint...however I can't figure out how.

I have a resize event in the usercontrol that does nothing but allows me to set a break in it. When I resize the app, which fixes the docking problem, this event gets fired and the call stack shows it being called (through some external code) from:

Telerik.Windows.Controls.dll!Telerik.Windows.Controls.RadDockPanel.ArrangeOverride(System.Windows.Size finalSize)

Is there a way I can force this to happen from code?

Thanks

I was wondering if it is possible to do something the following with the GanttView:

We have task A, B, C & D. They are all linked to each other in chronological order (A->B->C->D). When I move task B, is it possible to let Task C & D move as well so the time between them remains the same? So when i have moved B 3 days in the future, C & D are also moved for 3 days.

Kind Regards

Hi, I'm using a RadRibbonWindow as my main applictiaon window, and several RadWindows for some dialogs.
When I run the application and open a modal or modeless RadWindow from the main window and move focus to other applications or the desktop and then come back to my application, the focus goes to the main window and not the modal or modeless dialog. The floating dialog always hides behind the main window. How can I fix this?
Thanks!
