调整大小DataGrid不工作

Question

我可以调整窗口的DataGrid，直到我excecute验证码：

// Handle the tabcontrol animation 
DoubleAnimation dbTbViewsAnimation = 
    new DoubleAnimation(dToTabHeightParameter, new Duration(new TimeSpan(0,0,1))); 
this.tbViews.BeginAnimation(TabControl.HeightProperty, dbTbViewsAnimation); 


// Handle the tabcontrol animation 
DoubleAnimation dbCurrentPlaylistHeightAnimation = 
    new DoubleAnimation(dToCurrentPlaylistParameter, new Duration(new TimeSpan(0, 0, 1))); 
this.dgCurrentPlaylist.BeginAnimation(DataGrid.HeightProperty, dbCurrentPlaylistHeightAnimation); 

什么是这个代码的问题，为什么它会阻止数据网格大小调整？ 谢谢！

Answer 1

请参阅Timeline.FillBehavior Property。默认值是HoldEnd。你可以使用构造函数重载来改变这种行为。

DoubleAnimation dbTbViewsAnimation = 
    new DoubleAnimation(dToTabHeightParameter, 
         new Duration(new TimeSpan(0,0,1)), 
         FillBehavior.Stop);
