Docking Window Hint

[Jeff Johnson]

I''m programmatically adding a docking window with a treeview to an MDI form.

The treeview is set to fill the whole panel, but when it appears it doesn''t. If I resize it, then the treeview fills the form.

Any hints on what to do to get it to fill out right the first time?

Hi Jeff,

I haven''t experienced any problems getting a control to fill a Form when I set DockingManager.DockToFill=true. If that''s what you''re doing, do you have a sample that demonstrates this. Alternatively, if you''re doing something else, could you please describe your alternate method?

This code is running in your ''mdidemo'' sample.

It creates a tabbed window docked on the left of the application window. The treeview does not size properly unless you force it to redraw by stretching the window.

Hi Jeff,

I wasn''t able to test your code snippet as it references a number of variables that weren''t included in the snippet. Would it be possible for you to send me your entire project, or at least the class file? If you''re concerned about confidentiality, you can create a DirectTrac incident.

What I was able to determine is that you''re calling code from the sample''s constructor outside of the constructor. Due to the way VS.NET and DockingManager operate, that may result in different behavior. I would try moving the SetEnableDocking call to the very end of the sub, as I suspect that the early call causes the docking window to initialize before the TreeViewAdv is initialized, causing the incorrect size.

It''s beautiful, now.
