DataList嵌套问题

[vhanzhou]

<asp:DataList ID="dstProblems" runat="server" OnItemDataBound="dstProblems_ItemDataBound">
                            <ItemTemplate>
                                <b class="blue_ti">
                                    <%#Eval("TypeName") %></b><br />
                                <br />
                                <asp:HiddenField ID="hfTypeName" runat="server" Value='<%#Eval("TypeName") %>' />
                                <asp:DataList ID="dstChoiceAnswer" runat="server" OnItemDataBound="dstChoiceAnswer_ItemDataBound">
                                    <ItemTemplate>
                                        <%#Eval("Question")%>:
                                        <asp:HiddenField ID="hfQuestionID" runat="server" Value='<%#Eval("QuestionID") %>' />
                                        <asp:RadioButtonList ID="radlAnSwer" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow" CellSpacing="20">
                                        </asp:RadioButtonList>
                                    </ItemTemplate>
                                </asp:DataList>
                                <br />
                            </ItemTemplate>
                        </asp:DataList>
<asp:Button ID="btnSubmit" runat="server" Text="提 交" OnClick="btnSubmit_Click"/>

请问提交的时候怎么获取RadioButtonList.SelectedValue呢？

[vhanzhou]

protected void btnSubmit_Click(object sender, EventArgs e)
{
// 获取radlAnSwer.SelectedValue的值
}

在线等，各位高手快来

遍历datalist,findcontrol找到RadioButtonList
for (int i = 0; i < Datalist1.Items.Count; i++)
{
if (Datalist1.Items[i].ItemType == ListItemType.Item | Datalist1.Items[i].ItemType == ListItemType.AlternatingItem)
{
string id = Datalist1.DataKeys[i].ToString();
DataList Datalist2 = (DataList)Datalist2.Items[i].FindControl("Dtalist2");
//循环取

[残月照我心]

for (int i = 0; i < dstProblems.Items.Count; i++)
{
RadioButtonList radlAnSwer= this.dstProblems.Items[i].FindControl("radlAnSwer") as RadioButtonList ;//获取ID,找到ID,你应该可以找到它的值了
}

for (int i = 0; i < dstProblems.Items.Count; i++)
        {
            if (dstProblems.Items[i].ItemType == ListItemType.Item || dstProblems.Items[i].ItemType == ListItemType.AlternatingItem)
            {
                DataList dst2 = (DataList)dstProblems.Items[i].FindControl("dstChoiceAnswer");
                if (dst2 != null)
                {
                    for (int j = 0; j < dst2.Items.Count; j++)
                    {
                        
                    }
                }
            }

根据3楼的再修改了下，搞定！
