DocumentPane and ResizePanel

Feb 26, 2009 at 7:58 AM

I'm trying to set a ResizingPanel.ResizeWidth to a DocumentPane and it doesn't work. I saw in the demo that the ResizePanel properties works only with DockablePane but haven't any effects on a DocumentPane.

For example :

<ad:DocumentPane x:Name="_documentsHost" ad:ResizingPanel.ResizeWidth="200">--> The size will not be 200...
<ad:DockablePane x:Name="_dockableHost" ad:ResizingPanel.ResizeWidth="200">--> The size will be 200...

Is anybody knows why? Or there is another solution to set (progammaticly) the prefered size of a DocumentContent or a DocumentPane.

Thank you!!!

DocumentPanes always accopies all the available space, at least using the default template.
Why you should set to a preferred size for it?

In fact I have a DockingManager which might contain lot of DocumentPane.
I would offer a button to the user to redraw the DockingManager. In redraw, I mean take all DocumentPane and place them all in a square of equal distributed size.

For example :

Before redraw :  

DocPane 1
DocPane 2
DocPane 3
DocPane 6
DocPane 4
DocPane 5

After redraw (progammaticly) :

DocPane 1
DocPane 2
DocPane 3
DocPane 4
DocPane 5
DocPane 6

So, that's why I prefer to set a prefered size ;)

Thank you!

Ok, try to use code like this:

<ad:DocumentPaneResizingPanel Orientation="Vertical">
<ad:DocumentContent x:Name="doc1" Title="Doc1" />
<ad:DocumentContent x:Name="doc2" Title="Doc2" />
<ad:DocumentPaneResizingPanel ad:ResizingPanel.ResizeHeight="200">
<ad:DocumentContent x:Name="doc3" Title="Doc3" />
<ad:DocumentPane >
<ad:DocumentContent x:Name="doc4" Title="Doc4" />

DocumentPaneResizingPanel class is the key, it's the preferred container for
document panes.

It looks good but I missed to precise that I need to do this progammaticly because I don't know the number of DocumentPane present in the DockingManager...
I have to create the structure you wrote programmaticly...

Something like that :

DocumentPaneResizingPanel.SetResizeWidth(myDockManager, 200); //For orientation???

foreach (DocumentPane document in myDockManager.Documents) {
    DocumentPaneResizingPanel.SetResizeWidth(document , 200);
    myDockManager.Anchor(document , documentRelative, AnchorStyle.Bottom OR Right); //I have a specific code to get the relative Pane and the AnchorStyle which run correctly...

but it doesn't work...

Programmatically at runtime is more complicated because you need to
completely discard the current layout and recreate a new one from scratch.
This is a way to achive that, of course is not much tested:

DocumentPaneResizingPanel panelContainer =
_dockingManager.MainDocumentPane.Parent as DocumentPaneResizingPanel;
DocumentContent[] docs = _dockingManager.Documents;
//if panelContainer == null it means that we have a only docuument pane with
all contents in it
if (panelContainer == null)
ResizingPanel originalParentContainer =
int indexOfMainDocumentPane =
panelContainer = new DocumentPaneResizingPanel();
if (originalParentContainer.Orientation == Orientation.Horizontal)
panelContainer.Orientation = Orientation.Horizontal;
bool mainDocumentPaneIsSet = false;
foreach (DocumentContent doc in docs)
DocumentPane oldContainerPane = doc.Parent as DocumentPane;
DocumentPane docPane = null;
if (mainDocumentPaneIsSet)
docPane = new DocumentPane();
docPane = _dockingManager.MainDocumentPane;
mainDocumentPaneIsSet = true;
ResizingPanel.SetResizeWidth(docPane, 200);

Hi ado!

Sorry to answer you only now but my planning is very busy..
I used your code with some improvements and the result is absolutly perfect!

FYI I'm working on a project in Switzerland (Fribourg). Your DockingManager is used to show many video streams.
I want to say you a big THANK YOU!!!

If you want to know more about my project, tell me.

See you!
