Question

取GridView的模板中RadioButtonList的id时，提示NewSelectedIndex没有定义，怎么办？

代码为RadioButtonList rbl = GridView1.Rows[e.NewSelectedIndex].Cells[5].FindControl("RadioButtonList1") as RadioButtonList;
.aspx文件中的代码为<asp:TemplateField>
<ItemTemplate>
<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="True"
onselectedindexchanged="RadioButtonList1_SelectedIndexChanged">
<asp:ListItem Value="A"></asp:ListItem>
<asp:ListItem Value="B"></asp:ListItem>
<asp:ListItem Value="C"></asp:ListItem>
<asp:ListItem Value="D"></asp:ListItem>
</asp:RadioButtonList>
</ItemTemplate>
<ControlStyle Width="100px" />
<ItemStyle Width="100px" />
</asp:TemplateField>，请高手帮忙，谢谢啦。

你在哪个事件里写的啊

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
这个地方的e基本上没什么用，除非取父级然后强制转换
}

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
e.CommandArgument;
e.CommandName;
e.CommandSource;
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
e.Row.RowIndex;
}

你自己看看应该明白了
