Siverlight笔记

自动修改画板高度：

js:var oldsetComponentHeight = setComponentHeight; setComponentHeight = function(componentName, height) { oldsetComponentHeight(componentName, height); try { if (window.parent != null && typeof (window.frameElement) != "undefined" && window.frameElement) { window.frameElement.height = height + "px"; } } catch (e) { } } 

Siverlight:

In_Page(){ this.ContentStackPanel.SizeChanged += new SizeChangedEventHandler(delegate(object sender, SizeChangedEventArgs e) { double height = this.ContentStackPanel.ActualHeight; Data.Global.Current.Height = this.abc.ActualHeight; });}public double Height { get { return _height; } set { _height = value; if (_height <= 100) { _height = 100; } QTInteract.DataComposer.Current.Invoke("setComponentHeight", Data.Global.Current.Get("startPage"), _height); } }////For Control componentclass ControlBase:Canvas{XXX.Behavior.Other.SetAutoHeight(this.Root, this.LayerOut);//Root is Canvas, and LayerOut(StackPanel) is root's only child.}public static void SetAutoHeight(FrameworkElement root, FrameworkElement layerOut) { layerOut.SizeChanged += new SizeChangedEventHandler(delegate(object sender, SizeChangedEventArgs e) { double height = layerOut.Height; if (double.IsNaN(height)) { height = layerOut.ActualHeight; root.Height = height; } }); }

 

在Control中，请异步调用第三方方法，特别是那些可能包含回调的方法，否则会发生嵌套调用
 Dispatcher.BeginInvoke(() =>
                handler(rtn));

 

使用超时来提高mouse move事件的效率。
