如何得到嵌套在Repeater里的RadioButtonList控件的SelectedValue的值

[wjy217213]

aspx:
<table border="0" cellpadding="0" cellspacing="0" style=" margin-top:10px;" width="100%">
<asp:Repeater runat="server" ID="rptypelist" OnItemDataBound="rptypelist_ItemDataBound" >
<ItemTemplate>
<tr><td>
<asp:Label ID="lbId" runat="server" Text='<%#Eval("Id") %>' Visible="false"></asp:Label>
<asp:RadioButtonList ID="rblItem" runat="server"> </asp:RadioButtonList>
</td> </tr>
<tr>
<td >
<a href='voteCount.aspx?id=<%# DataBinder.Eval(Container.DataItem, "id") %>&voteDetailsID='><asp:Image ID="ImaVote" runat="server" ImageUrl="~/Images/btntoupiao.gif" o /></a>
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
.cs:
protected void RpTypeBind()
{
string strSql = "select * from voteMaster ";
ds = SqlExec.ExecuteDataSet(strSql);
this.rptypelist.DataSource = ds;
this.rptypelist.DataMember = ds.Tables[0].TableName;
this.rptypelist.DataBind();

}
protected void rptypelist_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
RadioButtonList rbl = (RadioButtonList)e.Item.FindControl("rblItem");
Label lbl = (Label)e.Item.FindControl("lbId");
DetailsID= Convert.ToInt32( rbl.SelectedValue);
if (lbl != null)
{
string strSql = "select voteDetailsID,voteItem from voteDetails where ID = " + Convert.ToInt32(lbl.Text.Trim());
ds = SqlExec.ExecuteDataSet(strSql);
rbl.DataSource = ds;//指定数据源
rbl.DataTextField = "voteItem"; //指定要显示的字段
rbl.DataValueField = "voteDetailsID";//指定主键字段
rbl.DataBind();//绑定Rd
}
}
}
如何得到嵌套在Repeater里的RadioButtonList控件的SelectedValue的值作为参数传给上面红色的voteDetailsID，因为voteCount.aspx需要voteDetailsID这个值，但是它却是嵌套在Repeater里的RadioButtonList控件的属性，怎么做？或者有没有其它替代方法来实现功能。请大家帮忙解决一下！！！

SelectedItem.Value没有值为什么呀？

[wjy217213]

不用每个票投完都点投票了，把投票按钮做一个放在Repeater外面，那又应该怎么做呀？

[C_NET_rgz]

RadioButtonList aa = rptypelist.findcontrol("rblItem") as RadioButtonList

兄弟你还在1.1啊，等下给你搞搞

<asp:RadioButton
应该用这个吧

[bychgh]

radiobuttonlist控件有一个叫SelectIndex的属性,这个个属性就是你选定时的索引值。radiobuttonlist.SelectedIndex
获取值的方法如下
radiobuttonlist1.selecteditem.value
在后台获取，再赋值给voteDetailsID，看行不？

[戒烟戒酒戒编程]

((RadioButtonList)e.Item.FindControl("RadioButtonList1")).SelectedValue;
基本上是这样写的 要是不行就换成这样
((RadioButtonList)e.Item.FindControl("RadioButtonList1")).SelectedItem.Value

RadioButtonList控件的SelectedValue的值能得到，我想问的是怎么传到前台<a href='voteCount.aspx?voteDetailsID='> <asp:Image ID="ImaVote" runat="server" ImageUrl="~/Images/btntoupiao.gif" /> </a> 的链接中，或传给嵌套在Repeater里的Button1的protected void Button1_Click(object sender, EventArgs e)
{
//Response.Redirect("voteCount.aspx?voteDetailsID="+);
}voteDetailsID中，
protected void Button1_Click(object sender, EventArgs e)
{
foreach (RepeaterItem ri in rptypelist.Items)
{
if (ri.ItemType == ListItemType.Item || ri.ItemType == ListItemType.AlternatingItem)
{
RadioButtonList rd = ri.FindControl("rblItem") as RadioButtonList;
if (rd.SelectedItem != null)
{Response.Redirect("voteCount.aspx?voteDetailsID=" + rd.SelectedItem.Value);
}
}
}
}
这种方法获取不到rd.SelectedItem.Value的值，不知道是什么原因，是不是因为RadioButtonList控件嵌套在Repeater里了？

顶一下，在线等答案！

问题也可以理解为嵌套在Repeater里的RadioButtonList控件同嵌套在Repeater里的Button控件传radiobuttonlist1.selecteditem.value 这一值

Response.Redirect是否执行了，如果没有执行page_load中是否加了if(!ispostback)
如果执行了试下是否能得到rd.SelectedItem.Text

[lovexilove]

findcontrol()

Response.Redirect执行了，但是得不到rd.SelectedItem.Text的值，怎么办？大侠

for(int i=0;i<repeater.Items.Count;i++)
{
RadioButtonList rbl=(RadioButtonList)repeater.Items[i].findcontrol("yourID");
rbl.Text;//这就是你的值 手写的 自己拿过去改下
}
