I am trying to do MVVM with data binding to GraphSource using a ObservableGraphSourceBase.  When I drop a container from the DiagramToolbox.  How would be able to associate that container with view model item and still be able to undo or redo adding that item to the diagram?

Hello,

I'm wondering how I can let a header do texttrimming?
In the picture below, you can see that my column values are being trimmed, but the header text isn't..

Hi,

how can i add a errorhandling to a RadMaskedTextInput? On LostFocus-Event i check if the Input is ok or not. If the
Input is not ok, i want to clear the RadMaskedTextInput and set the Cursor back in the box.

To clear is no problem:

RadMaskedTextInput.Text = "";

But how to set the Focus?

RadMaskedTextInput.Focus(); does not work.

Thanks Best Regards
Rene

How do I prevent the selction changed event from firing when a listbox item is selected for drag drop?

The main WPF form contains the RadDock. The RadDock has a RadPaneGroup that is docked left. RadPanes containing RadListBox controls are added to this RadPaneGroup based on user selection, an example being a list of customers.

The RadDock has a second RadPaneGroup, and this RadPaneGroup is in the DocumentHost property of the RadDock so that its RadPanes open as tabbed documents.

An example of normal behavior is that a RadListbox containing a list of customers appears in a RadPane that is in the docked left RadPaneGroup. A user selects a specific customer from the list, the selection changed event fires, and the application adds a RadPane to the Document host RadPaneGroup so that details about the selected customer are shown as a tabbed document.

One of the user actions is to create a shopping cart. A menu option is chosen and a RadPane containing the shopping cart information is added to the DocumentHost RadPaneGroup. The first thing that a user needs to do is associate a customer to the shopping cart. The idea is that the user would drag a customer from the RadListbox contained in a docked left RadPane onto the RadPane that is in the document host RadPaneGroup and shown as the currently active tabbed document.

My problem is that when I left click and hold down the mouse button to drag an item out of the RadListbox that is in the docked left RadPaneGroup, the RadListbox selection changed event fires, which then opens a customer details RadPane in the tabbed document DocumentHost area; the shopping cart is no longer visible because it is no longer the active tab.

The desired behavior is that the RadListbox selection changed event does not fire during a drag / drop operation so that I can drag the selected customer from the RadListbox contained within the docked left RadPane onto the empty shopping cart RadPane that is displayed as a tabbed document in the DocumentHost.

Do you have any vb.net examples, or documentation that would explain the desired behavior?

Hello, i'll wrote my app with mvvm pattern and have a problem with selecting item programmatically in resourcedictionary.
I have TreeListView on the one resourcedictionary and GridView in another. Also I have two ObservableCollection 1 and 2 wich i bind.

Hi,

i'm using the "Grouping and Filterung" Example of SchduleVIew. Ther you Add the ResourceTypesSource in xaml.
How do i add the Resources by code behind in this case?

XAML:

I have used RadChart for displaying graph, On legend i have used chekboxes for each item. upon which the respective series will be show/hide.On opening the form the data is loaded and legend items are checked by default. The problem is that when i unchecked the items and then scroll the chart or zoom in the checboxes are automatically checked, although the series are hidden as i have already uncheck the items.Why the checkboxes are automatically got checked on zooming or scrolling.I want the checkboxes to remain unchecked

User control class

   

here is the XAML code


View model class


WPF application class

Binding a view model property to the SearchText property of a RadAutoCompleteBox seems to have no effect (when typing in the RadAutoCompleteBox, the view model property remains null).

Is this by design? Is there a workaround?

Hi,
Is there a way of setting the ZIndex of a CustomGridLine?
I have a BarSeries with two CustomGridLines and I want the GridLines to be over the bar.
The way it is now is that the bar is over the GridLines.

See attached image.

Thanks in advance.
