我有一个嵌套的GridView到5个级别，我很难访问在第二级GridView中选择哪个RadioButtonList。 （第一级被命名为gvSecondLevel，所以请不要混淆）。我现在必须从gvThirdLevel访问（实际上是第二级网格，你会在代码中看到）。我不确定问题是ASPX代码还是c＃代码。我已经尝试将rbThirdLevel放在TemplateField中，没有它。但无论如何我无法访问它。这是aspx代码：

C＃代码只是返回＆＃34;活跃＆＃34;即使我选择＆＃34; Inactive＆＃34;。请指导访问rbThirdLevel
的正确方法 protected void rbThirdLevel_SelectedIndexChanged(object sender, EventArgs e)
{
foreach (GridViewRow row in gvSecondLevel.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
GridView gvThirdLevel = (GridView)row.FindControl("gvThirdLevel");
if (gvThirdLevel != null)
{
RadioButtonList rbThirdLevel = gvSecondLevel.Rows[row.RowIndex].FindControl("rbThirdLevel") as RadioButtonList;
string radiovalue = (gvSecondLevel.Rows[row.RowIndex].FindControl("rbThirdLevel") as RadioButtonList).SelectedItem.Value;
if (rbThirdLevel.SelectedValue == "Inactive")
{
//code to display Deactivated rows
}
if (rbThirdLevel.SelectedValue == "Active")
{
//code to display Activated rows
}
}
}
}
}
