列表的哪个gridview触发事件

Question

我有一个GridView List ，我想在每个GridView上添加相同的CellEndEdit事件。

有可能确定哪个gridview触发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
}

标准事件模式将事件源作为参数传递给sender参数。 所以你可以简单地将sender RadGridView为RadGridView并拥有相关的实例：

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

显然在这种情况下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
}
