支持鼠標雙擊事件的DataGrid

Silverlight控件到目前爲止都不支持雙擊事件，但是我們可以自己來擴展控件以支持雙擊事件，下面便是對DataGrid的擴展：

public class QFDataGrid : DataGrid { private DateTime _clickTs; public event EventHandler<EventArgs> DblClick; public QFDataGrid():base() { _clickTs = DateTime.Now; this.MouseLeftButtonUp += new MouseButtonEventHandler(QFDataGrid_MouseLeftButtonUp); } void QFDataGrid_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { DateTime now = DateTime.Now; if (now.Subtract(_clickTs).TotalMilliseconds <= 200) { if (DblClick != null) { DblClick(this, new EventArgs()); } } else { _clickTs = now; } } }

 

原理就是模擬雙擊了
