获取动态下拉列表选择的行索引 [英] get selected row index of dynamic dropdown list selection

问题描述

我知道这个问题有点波澜不惊，也许是误导，但是我有一个gridview，在行上有下拉列表。我为SelectedIndexChanged创建了一个AddHandler和一个Delegate，并且它被赋予了sub。以下是代码：

I know the question is a little choppy and perhaps misleading,but I have a gridview with dropdownlists on the rows. I created an AddHandler and a Delegate for the SelectedIndexChanged and it gets to the sub. Here is the code for that:

AddHandler ddlmgr.SelectedIndexChanged, AddressOf ddlmgr_SelectedIndexChanged
Public Delegate Sub DropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As DropDownList_SelectedIndexChanged)

Protected Sub ddlmgr_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)


End Sub

如果GridView_RowCommand没有被调用，我该如何获取行的Id？

How can i get the row's Id if GridView_RowCommand is not called?

推荐答案

伟大的工作
为我工作非常好

Great work Works absolutely fine for me

DropDownList ddl = (DropDownList)sender;
Control p = ddl.Parent;
//you are going to loop because the immediate
//parent may not be the repeater item but instead a 
//container control of some kind (say a template)
while (p.GetType() != typeof(RepeaterItem))
{     
  p = p.Parent;     
  if (p == null) 
      return; //we have reached the top of the control tree
}
RepeaterItem ri = (RepeaterItem)p;
int index = ri.ItemIndexreturn index;
