推荐答案

你可以设置你

Horizo​​ntalAlignment =拉伸和

VerticalScrollBarVisibility = Auto



如果这不起作用，将网格的高度绑定到窗口高度因此它不会自动增长以适应它的内容。



高度={Binding RelativeSource = {RelativeSource AncestorType = {x：Type Window}}，Path = ActualHeight}（可能是RenderSize.ActualHeight insetad只是ActualHeight）



另一种替代方法是使用DockPanel而不是Grid，因为该控件不会自动成长以适应它的内容。相反，它会拉伸它的最后一个孩子来填充所有剩余的空间。

You can set you
HorizontalAlignment=Stretch and
VerticalScrollBarVisibility=Auto

If this doesn't work,Bind the Grid's Height to the Window Height so it doesn't auto-grow to fit it's contents.

Height="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}}, Path=ActualHeight}" (It might be RenderSize.ActualHeight insetad of just ActualHeight)

Another alternate is to use DockPanel instead of a Grid since that control doesn't auto-grow to fit it's contents. Instead it'll stretch it's last child to fill all remaining space.
