Notification when the treeview gets re-arranged after dropping

Hello.

Like the title says, I need a notification when the drag and drop operation is finished and the dropped item has been moved to it's correct position, this is because I need the new position of the item.

I'm not using the native D&D in the RadTreeView, but I'm using the RadDragAndDropManager to handle my D&D. Also as I was told here that in order to handle the D&D on my own I have to set the e.Handled to true in the PreviewDragEnded event.

So basically I just need an event that happens after:

1) The drop has finished

2) The tree view has been rearranged to update the new position of the dropped item

At that point, I should be able to find the dropped item and call this to get its new coordinates (reference):

GeneralTransform generalTransform = droppedItem.TransformToVisual( parentElement );

Point childToParentCoordinates = generalTransform.Transform( new Point( 0, 0 ) );

Let me know if this is possible. Thanks!

Load / Save state needs UpdateLayout?

Hi Telerik,

I was implementing the demonstration of loading/saving the GridView state from the demo application.
All worked well, the state was saved/loaded, except the GroupBy toolbar was not filled from the last state.

By implementing this.grid.UpdateLayout(); inside the Loadstate function solved my problem.

Is this the correct way?, Or should the example have worked 'out of the box'?

With kind regards,
Rob

Binding RadComboBox not working when collapsed

Hi,
I have a RadComboBox that is in a RadExpander which I have bound to a public property that returns a set of key value pairs. I copied this same RadComboBox, renamed it, and placed it in a DataTemplate for a ListBox so when a User Selects the item in the ListBox the static text's visibility collapses and the editable fields are presented. I am running into the problem where the RadComboBox doesn't bind. The initial visibility of the RadComboBox is collapsed. Any Ideas?

Problem with auto sizing

I had a problem with Gauge auto sizing.
When I assign the RadGauge control of width and height in NaN (the minimal width and height equal 0, VerticalAlignment and HorizontalAlignment – Center), I receive a control of 100 x 100 no matter what container I have (Grid, StackPanel, Canvas), though I expected to see the control of 0x0 size.
Can you tell me, why it happens? How can I avoid such situation and make auto sizing work correctly?

Sort order of groupings

Hello,

I have a grouping in my grid which is specified in xaml. The grouping has two possible values, "Live" and "Paper".

I'd like to ensure that the "Live" grouping is always on top, regardless of how the user sorts data in the grid. (They cannot sort by the column I am using to group by).

How can this be accomplished?

Thanks
