Way to make WPF DockPanel auto-resize based on its children's size?

问题

Right now I have a DockPanel that contains a toolbar and BrowserWindow. When I re-size the BrowserWindow to fit content, I want that change to propagate up into the DockPanel and re-size automatically. Is there a setting for this?

So the layout of my app is essentially:

-Browser Control Class

--DockPanel

----Toolbar (docked to Top)

----Browser Window Class

------Grid

--------Menu

--------Embedded Browser

Basically I want the size that I set on my Browser Window Class to automatically re-size the DockPanel.

Before applying size to Browser Window:

DockPanel has a LastChildFill property that you can use. Try to play with it a little. Remember that BrowserWindow needs to be the last child in DockPanel.

I think you will also have to change something in your Grid. By LastChildFill property should be set. You are on right track at least.

Change your DockPanel to a StackPanel, put it inside a Grid, and set it's HorizontalAlignment and VerticalAlignment to Center

You might also need to play with the the Height/Width of the WebBrowser to specify the initial size

<Grid>
    <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
        <Menu />
        <WebBrowser Height="SomeValue" Width="SomeValue" />
    </StackPanel>
</Grid>

Can't you specify Width="Auto"?
