How to know when a control in a DockableControlPane is visible
posted

Hi,

I want to implement docking in our windows, but I have a little problem.
Our windows typically contains lots of data which often is master-detail related,
so lets say that we have a master grid and the active row in that grid controls the
data in 5 other grids. I want the users to be able to show/dock/tab/hide these
5 grids as they want. The data in a detail grid is fetched fom a server when the
master row changes and I don't want to get any detail data for a detail grid that is not visible
to the user.

Therfor I need to know when a control in dockablecontrolpane is visible or not, and also
I like to have an event when this state changes. This way a detail control will be notified
that "now you are visible" (for instance selected in a tabgroup, or flied out) so it can be populated
with data for the master row. And similar that the Control/Pane knows that
it is visible when the master row changes and retrieves the data directly.

I have been experimenting with the docking, but haven't found out how to this in a correct
and reliable way.
