In scenarios where the RadTaskBoard's TaskBoardColumnsPanel scrolling is disabled, the panel's calculated height leads to the RadTaskBoardItems being cut off. The panel should instead stretch vertically to display all its child items.

When the theme is changed runtime in the NoXAML scenario, the control is not visible anymore.

Currently, the card model is added to a group when initially added to the ItemsSource of RadTaskBoard. Also, it can be moved to another group by drag/dropping on it. However, if you update the card model property that is assigned to the GroupMemberPath of RadTaskBoard, then the card is not moved to the corresponding group in the UI.

To work this around, remove the card object from the ItemsSource, update the group property and then add the card object back in the ItemsSource.

Create an API to customize the DragDrop behavior.

When placed in TabControl, for example, and the TabItem with the TaskBoard is deselected (leading to the control being unloaded), the items are cleared when the TabItem is selected again. 

The Height property of the RadTaskBoardItem is not respected when setting to a different value thus preventing us to have items with different height.
