列表的哪個gridview引發事件

Question

我有ListGridView，我想在每個GridView處添加相同的CellEndEdit事件。

有可能確定哪個gridview觸發了CellEndEdit事件？

lst.Add(new RadGridView()); 
RadGridView radgridview= lst.Last(); 
radgridview.CellEndEdit += new GridViewCellEventHandler(radgridview_CellEndEdit); 

private void radgridview_CellEndEdit(object sender, GridViewCellEventArgs e) 
{ 
    //I want to know here which radgridview is modified 
}

標準事件模式在sender參數中傳遞事件的來源作爲參數。所以，你可以簡單地投sender到RadGridView，並有相關的實例：

private void radgridview_CellEndEdit(object sender, GridViewCellEventArgs e) 
{ 
    RadGridView sendingGridView = sender as RadGridView; 
    if (sendingGridView == null || !lst.Contains(sendingGridView)) 
     return; // just to be sure 
}

顯然，在這種情況下，sender是GridViewEditManager，所以你可能會得到您的RadGridView這樣的：

private void radgridview_CellEndEdit(object sender, GridViewCellEventArgs e) 
{ 
    GridViewEditManager manager = sender as GridViewEditManager; 
    RadGridView sendingGridView = manager?.GridViewElement?.GridControl; 

    if (sendingGridView == null || !lst.Contains(sendingGridView)) 
     return; // just to be sure 
}
