     Hi,

I'm facing an issue with RadCalendar placed inside a RadDocking control. The DisplayDateChanged event is called whenever I dock or undock the calendar from the docking control. I've bound a data refresh command to the said event, but dock/undock causes the command to be fired without being needed.

Here is the Xaml:

<telerik:RadCalendar>

<behaviors:EventTrigger EventName="DisplayDateChanged">
       <behaviors:InvokeCommandAction Command="{Binding Path=RefreshDataCommand}" CommandParameter="{Binding                        ElementName=ctrlCalendarView, Path=DisplayDate}">
</behaviors:InvokeCommandAction>
</telerik:RadCalendar>

RefreshDataCommand is coming from ViewModel.

What the issue is this, please look into the matter.

Thanks.

As far as I can tell, MultiColumnComboBox does not have a TextSearchMode or IsSynchronizedWithCurrentItem property like the RadComboBox.  I'm looking to implement the Contains value of TextSearchMode. 

I also want the MultiColumbComboBox to display the current item at startup.  (using only one item at a time)  Is there another way to do these things?  Thanks.

Hello, I need to convert a RadDiagram to PDF/A-1a. I managed to convert it as an image, but that's not good enough. I need a vector format, because I need the text in the shapes, and my custom templates. Converting to SVG would be good enough, I can try to take it from there.

I saw your sample in http://docs.telerik.com/devtools/wpf/controls/raddiagram/features/html-support, but I need images, and I use custom templates.

I tested the ExportToPdf sample in the SDK, and it looks like a good start. I was thinking of adding image and custom shape support to it, but if it doesn't export to PDF/A-1a in the first place, it's a non starter.

Is there a way to export a RadDiagram to a PDF/A-1a document, even if images and custom shapes aren't supported ?

Hello Telerik,

Any tips on how to enable selection of a GridViewRow from a right mouse click?

There are plenty of examples demostrating how to do this when a ContextMenu is involved, but I do now want a ContextMenu in my case.

Thanks in advance!

Regards,
Roland

Hi Gyus,

we have the following scenario:

UI with a RadListBox and a RadScheduleView
The ListBox contains custom business objects

We want to drag and drop these business objects to the ScheduleView.

So we need the following:

A custom DragSourceBehaviour for the RadListBox (checked and works)
A custom DragDropBehaviour for the ScheduleView (checked and works)
So far so good...

But now the problems starts:

We need a custom appointment that implements the only interface IAppointment.
We don't need any further appointment interface like IExtendedAppointment or IObjectGenerator.
But we can't inherit from the Appointment base class, because we already inherit from our own base class.

If we implement the IAppointment interface, the drop on the schedule view doesn't work!
And unfortunately we don't understand why. And believe me, we have tried many variants.

We know all your samples from the sdk and from the forum (for example: WithDB and the example from 2012)
But all these examples don't just implement the IAppointment interface.

And when is the Drop operation completed?
If you drag and drop only inside the ScheduleView there is as DragAndDropCompleted event. 
But, if you drop from another control, there is no completed event!
We have to write the changed data directly into the database. So we need to know when the drop processes are completed.

Can you please tell me the two drag and drop lifecycles (internal drag and drop as well as drop from another control)?

Thank you very much.

I have looked over the examples for selecting items from the Visualization layer, specifically "Visualization Layer Items Selection" but they all seem to require adding event handlers in the code behind. Is there a way to select items without having to add an event handler in the code behind and keep all the logic in the viewmodel? Normally I just use data binding with the ItemsSelected property but that doesn't seem to be working.

Hi, 

I have an app that uses voice control. When a command is ambiguous (i.e. meaning it returns multiple potential results), I want to pop up a model window displaying a list of those potential results, preferably in a grid. I then want to allow the user to simply click the row in the grid containing the desired command (or data value), and return that selected value to the calling window.

To further complicate matters, the voice-control mechanism (cognitiveservices.speech) listens on a secondary thread, so I want the modal dialogue to suspend not only suspend the activities of the calling window until the user makes his/her selection, but also the listening thread.

Any guidance?

Please refer to the attached screenshot of the chart I am attempting to reproduce with the ChartView control.

Each item on the horizontal axis has a start and end value.

Would this be some kind of custom bar chart?

Is it possible to define your own series type? - Would that be the approach here?

The vertical lines would be nice to have but aren't a priority.

Hello,

I have the following problem with the Schedule View.

When I display a resource multiple times in a calendar, the appointments are only displayed in one slot. The problem can also be seen in the Telerik WPF ScheduleView demo "filter sub-group headers". Sven Ottlieb is in Level Basic, Advanced and Expert, but the dates are only displayed in Level Expert. Is there a solution?

Thank you very much.
Best regards,
Helmut
