Hello,

I have successfully bound a list of items to a RadListBox ItemSource, and bound to one column as a RadPropertyGrid. The other column, we want to appear as RadChart, somehow binding to a data series. The underlying model is in the form of List Pair of TimeSpan and Double. Possibly we directly bind to this, or at least Path-ing our way into the domain model, i.e. TotalSeconds, TotalMilliseconds, etc.

Doable?

Possibly I could start with programmatically doing it, but I'd like to go the XAML route and data bind if I could. Have worked with more than one chart in this manner before.

Thank ye...

Best regards,

Hi,

Is it possible to use SigralR as datasource with GridView?

My case is that the same database is used in my WPF application and in my web. My idea was that SignalR is used for propagating changes done in other ends. (add, delete and moved rows by drag-drop)

I was inspired by this great Kendo example:  http://demos.telerik.com/kendo-ui/web/grid/signalr.html

Hi,
I have a RadPaneGroup where I want to add the items on a button click.
So:



On button click I add a new RecordTabViewModel to the collection.
This works perfect the content and the header are displayed correctly.
But an error occurs when I want to switch between the Tabs:

Whilst working with the telerik property grid for wpf, I realised that it automatically implemented an undo/redo command on each property in the property grid. I was wondering if there was a way I could bind this command to say a button that could be clicked for usability's sake (not individually, but for the grid as a whole).

Thanks very much in advance!

Is it possible to add scroll bars to the mail merge field drop-down box? Our mail merge source can have 15+ fields in it. When a user is editing RTB content and clicks the Insert Merge Field button the list pops up but half the fields are not visible and there's no way to scroll the list. Does this require handling the insert command and customizing the drop-down? Even turning on CanVerticallyScroll doesn't seem to help.

No matter which value I use for TabStripPlacement, it's drawn at the top.  Why?

After using the Radpane, the selected item is not having the style applied. If RadTreeView alone is used (without having radpane), the selected item in the radtreeview is having the style SelectionUnfocusedVisual which is working properly (i.e), Selected Item gets Highlighted. How to make the selected item in the radtreeview to have a style applied (or) to highlight the radtreeview selected item when a radpane is used?. Thanks.

I posted a thread two days ago about a problem I was having with e.Handled in a RadDocking.Close event.  After looking at the code, I moved the logic to the PreviewClose event; however the result is the same.  I am attempting to close all the panes in a RadPaneGroup inside the DocumentHost.   I have tried...

• RadPaneGroup.HideAllPanes(), but the panes remain visible.  After the call I can close all but the first pane indiviually using the close button on each tab.  If I drag the last remaining pane off the tabstrip it disappears.
• Any direct manipulation of the RadPaneGroup.Items, whether a call to Clear(), Remove(pane), RemoveAt(index) causes an n "Object reference not set to an instance of an object." exception after exiting the handler with e.Handled set to true.

All of this happens in 2012.2.620 and did not happen in 2012.2.607.  Please let me know if there is a way to achieve this functionality without having to revert to using the previous version.

Thanks in advance, Steve

Hello,

I already implemented some drag and drop behaviors in my application. To do so, I create a DragVisual in the OnDragInitialize event (registered via DragDropManager.AddDragInitializeHandler), and I give it a DataContext (a Content actually) and a ContentTemplate. Then I can have a nice preview of the data being dragged that I can template as I wish and that will follow the mouse cursor.
This work perfectly when I'm dragging data from my app, to my app.

Now I am willing to be able to drag files, from the windows explorer, to a specific control of my application. I would like to create a DragVisual in the same way, when the mouse cursor enters one of the windows of my application (and destroy it if the mouse cursor leaves the window, but this is another problem).

The problem is that when the drag starts from another application, OnDragInitialize is not invoked (which makes perfectly sense). But how can I achieve to create a DragVisual in this context? None of the other drag'n'drop-related events have a DragVisual in their EventArgs.

Thanks
