列表的哪個gridview觸發事件

Question

我有一個GridView List ，我想在每個GridView上添加相同的CellEndEdit事件。

有可能確定哪個gridview觸發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
}

標准事件模式將事件源作為參數傳遞給sender參數。 所以你可以簡單地將sender RadGridView為RadGridView並擁有相關的實例：

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 ，所以你可以得到你的RadGridView ：

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
}
