調整大小DataGrid不工作

Question

我可以調整窗口的DataGrid，直到我excecute驗證碼：

// 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); 

什麼是這個代碼的問題，爲什麼它會阻止數據網格大小調整？ 謝謝！

Answer 1

請參閱Timeline.FillBehavior Property。默認值是HoldEnd。你可以使用構造函數重載來改變這種行爲。

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