repeater列表中直接修改状态

<asp:Repeater ID="RepeaterArticleList" runat="server" onitemdatabound="RepeaterArticleList_ItemDataBound">
   <ItemTemplate>
           <asp:HiddenField ID="HiddenField1" Value=<%#Eval("ID") %> runat="server" />  

    <asp:DropDownList ID="droplist1" runat="server" OnSelectedIndexChanged="DropDownList1_Change" AutoPostBack="true" >
                  <asp:ListItem Text="启用" Value="1"></asp:ListItem>
                  <asp:ListItem Text="禁用" Value="2"></asp:ListItem>
                  <asp:ListItem Text="删除" Value="3"></asp:ListItem>
         </asp:DropDownList>
   </ItemTemplate>
</asp:Repeater>

cs代码中对应的DropDownList1_Change方法，取到用户ID，执行操作

protected void DropDownList1_Change(object sender, EventArgs e)  
    {  
        DropDownList drd = sender as DropDownList;  
        Repeater rps = drd.Parent.Parent as Repeater;  
        int n = ((RepeaterItem)drd.Parent).ItemIndex;  
        HiddenField hid = (HiddenField)(rps.Items[n].FindControl("HiddenField1"));  
        string userid= hid.Value;     
        string userState = Convert.ToInt32(drd.SelectedValue);  

        //已经拿到了id，可以进行操作   

        YourFunction(userid,userState);          
    }  

在前台显示的时候，再根据用户的状态值，来选择下拉菜单的默认选中值首先为RepeaterRepeater 控件添加事件 onitemdatabound="RepeaterArticleList_ItemDataBound" 接下来是完成代码

protected void RepeaterArticleList_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        DropDownList drd = (DropDownList)e.Item.FindControl("droplist1");
        HiddenField hid = (HiddenField)(e.Item.FindControl("HiddenField1"));
        //用你的方法通过ID得到状态值到userstate
        string userstate = getUserStateByID(hid.Value);
        drd.SelectedValue = userstate ;  

    }
