We are using the licenced version of the silverlight docking panel (provided by Telerik) inside a region of the main shell (We are using a framework following the Microsoft Prism pattern). This framework has two modes. One is normal mode and other is full screen mode. In the full screen mode the user will not be able to see any menu and the complete page is filled with the region (which holds the dockable panes).
When user wants to move around the dockable pane and place it in another position, he would be displayed indicator for proper positioning. (The behavior is same as the dockable panes of visual studio).
If user moves the dockable pane and tries tio position it elsewhere in the full screen mode of the shell, then the indication for proper positioning is coming at the correct position of the cursor. But in the normal mode the indicator is displayed when the cursor is at an offset to the correct position.
Have a look at the attached screenshot and let us know how we can adjust this indicator offset.
Please get back to us as soon as possible.
