silverlight弹出子窗体不能居中
请教个问题。有个查询子窗体,继承于ChildWindow,有时候可以居中,有时不居中,拖动一下,下次再打开还有记忆窗体位置的功能。
[解决办法]
控制silverlight的childwindow,可以通过扩展类实现,例如:
public partial class ChildWindowEx : ChildWindow
{
Point _pt = new Point(0,0);
public ChildWindowEx()
{
InitializeComponent();
}
public ChildWindowEx(Point pt) : this()
{
_pt = pt;
}
protected override Size ArrangeOverride(Size finalSize)
{
Grid grid = Utils.FindChild<grid>(this, "ContentRoot");
if (grid != null)
{
grid.Arrange(new Rect(_pt.X, _pt.Y, grid.DesiredSize.Width, grid.DesiredSize.Height));
return finalSize;
}
return base.ArrangeOverride(finalSize);
}
}
