Ok thanks. I'll try to alter your PreferredSizeDecorator class to add PreferedMinimumHeight to it.

Thanks,

Imad.

Thank you for your reply. I noticed that when bottom right content pane is visible then I am get this problem of extra tall grids in other content panes. So probably you can suggest a better way of displaying bottom right contentpane (that doesn't make other contentPanes to display inappropriately) than what I am doing right now.

As I mentioned in my 2nd reply, I see the issue you are describing but only when using an HwndHost (e.g. WindowsFormsHost, WebBrowser, etc.). If you have that combined with content that wants to be really tall coming from a SplitPane that doesn't have an explicit extent it's going to have that issue. So if you modified the sample and put another contentpane on the right that had a webbrowser you see the issue you originally described about the top of the flyout going off screen. An issue will be entered for that and we will look into addressing it.

I also tried your PreferredSizeDecorator method of setting PrefferedHeight and PrefferedWidth. Only PrefferedHeight works in case of two grid content panes in that sample. It doesn't work for bottom right contentpane which when unpinned shows only title bar.

It is meant to deal with the case where the measure size exceeds a given preferred size and that constrained size is what the decorated/contained element is measured with but it still just returns the DesiredSize of that element after measuring it. So if the element wants to be less (as is the case when you have an empty ContentPane) then it is going to be less. If you want different behavior - like enforcing a soft minimum height - then you would need to alter that to meet your requirements.

Here is the image of problem in my original application. I have tried to hide the contents but I hope you would be able to identify the ContentPane that contains XamDataGrid going out of bounds of application and desktop when its unpinned and mouse is hovered above its tab.

On a hunch, I tried modifying your sample to contain an HwndHost (in this case I just created a ContentPane on the bottom that had a WebBrowser) and then was able to reproduce the issue when unpinning the grid on the bottom left. I've forwarded this to DS so a case can be created for the issue. Using the approaches (i.e. the PreferredSizeDecorator) I mentioned in those posts that I linked to in my previous reply should deal with this this as well since you probably don't want them being that tall anyway.
