如何访问控件的ListView EditItemTemplate中

我有问题，在验证radUpload的事件中使用Telerik的radupload在ASP中的ListView EditItemTemplate.i我要检查一些要求，所以我需要的FindControl两个控制：radUpload和标签为了这个，我我使用ItemDataBound事件listView 但问题是在这里，第一个ItemDataBound事件执行和之后，RadUpload验证事件将执行，因此RadUpload控制和标签控制保持空我通过使用静态控制的方式处理这个，但我认为这不是个好主意。你有解决方案吗？的另一个问题是使用静态我标签label.however和跟踪显示标签有文字，但在输出标签没见过如何访问控件的ListView EditItemTemplate中

你应该试试这个。

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e) 
{ 
    if (e.Item.ItemType == ListViewItemType.DataItem) 
    { 

     ListViewDataItem dataItem = (ListViewDataItem)e.Item; 
     if (dataItem.DisplayIndex == ListView1.EditIndex) 
     { 
     TextBox tb = e.Item.FindControl("tbFK_MenuID") as TextBox; 
     } 
    } 
}
