c# - 列表的哪个 gridview 触发事件

Question

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

可以确定哪个 gridview 触发了 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
}

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 转换为 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
}

很明显，在这种情况下，sender 是一个 GridViewEditManager，因此您可以像这样获取 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
}
