Question

I defined a Window in WPF, into this one I put a “stack panel” and inside this panel I put a “tab control” and some “button controls”.

When executing the program, I would like that when I have to resize the window using the mouse, the stack panel and all controls inside it can also be resized automatically and proportionally to the window.

How can I get this?

Thanks!!

A StackPanel only uses the space that its child controls need; it does not resize to the available space of the window.

If you want this behavior, use a different type of panel: If you only want the tab control to resize, use a DockPanel and make the tab control the last child of the DockPanel. A DockPanel stretches to the available space of the parent, with the last child getting all the space not used by the previous children.

<DockPanel>
    <Button DockPanel.Dock="Bottom" />
    <Button DockPanel.Dock="Bottom" />
    <TabControl>
        ...
    </TabControl>
</DockPanel>

If you need more complex spacing behavior (for example, you want the Buttons to proportionally take up more space as well), have a look at the Grid control.
