Question

1.我在父网格中有一个网格，嵌套网格中有一个链接按钮。

2.对于链接按钮，我需要使用嵌套网格的项目命令事件，或者我也可以使用父网格的项目命令。

3.问题是当我点击嵌套网格中的链接按钮时，如果父网格工作正常，则不会触发项目命令事件nestedgrid.But。

4.我已尝试处理程序和项目创建事件也在后面或在aspx中的代码中使用处理程序。但是没有任何帮助我获得嵌套网格的项目命令事件命中。

5.以前在转发器的情况下，有一个项目命令处理所有网格。我为孩子和父母尝试了不同的项目命令事件，但它也没有用。

编辑：这是代码示例

Answer 1

没有看到你的一些代码，我不能确定这个问题在哪里。我尝试的第一件事与telerik的API here类似。在对命令项执行任何操作之前，您需要确保使用正确的OwnerTable。使用这样的东西，确定该项目是针对正确的表格，然后你应该有权访问它。

 //identify to which table belongs the currently bound item
        if (e.Item.OwnerTableView.Name == "MyUniqueTableName")
       {
        //process requested operations
       }

修改

我明白你要做什么。我想你可能会采取错误的方式。查看telerik的demo page here上的层次结构部分。这是非常有用的信息，我有一个4层的层次结构，只需几个小时即可完成一些代码，只有1个radgrid。

Hello在嵌套视图中只能绑定一条记录，为了获取嵌套视图中的控件，我使用类似的东西。

protected void gvwData_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item.ItemType == GridItemType.NestedView )
    {
        GridDataItem item = e.Item as GridDataItem;
        HtmlGenericControl InfoDvi= (HtmlGenericControl)e.Item.FindControl("DivWithServerSideTagName");
    }
}
