后台代码：
repeater1绑定数据
 protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)

解决方案 »

  1.   

    我想 取到 checkbox的值。并保存到数据库。
    希望各位帮我下谢谢了
      

  2.   

     inputs[i].checked= true;
      

  3.   

    你是想在后台取，还是前台？
    后台的：
     for (int i = 0; i <= Repeater1.Items.Count - 1; i++)
                    {
                        HtmlInputCheckBox cb = (HtmlInputCheckBox)Repeater1.Items[i].FindControl("cbSelect");
                        Label id = (Label)Repeater1.Items[i].FindControl("lbid");
                        Label name = (Label)Repeater1.Items[i].FindControl("lbName");                    if (cb.Checked)
                        {
                            ids += id.Text.ToString() + ",";
                            names += name.Text.ToString() + ",";
                        }
                    }你可以加个label;checkbox只是做选中操作。
      

  4.   

    CheckBox gv = e.Row.FindControl("GridView2") as CheckBox ;
      

  5.   

    前台的话，你就用<input reunt="server"/>
      

  6.   

    麻烦大家 看下 我上面贴的代码，谢谢了
    我贴的代码 已经可以实现 选中了
    但是我不知道 选中的
    checkbox 怎么把值保存到数据库中
    就是不知道怎么取 到值
      

  7.   

    if(!IsPostBack)
     BindData();
    foreach (RepeaterItem item in Repeater1.Items)
      {
      CheckBox Chk= (CheckBox)item.FindControl("chk");//通过Hiddenfiled获取ID
      if(Chk.Checked)
      {
        
      }
      }var table = document.getElementById("<%=Repeater1.ClientID %>");
      var inputs = table.getElementsByTagName("input");
      for(var i=0;i<inputs.length;i++){
      if(inputs[i].type=="checkbox"){
        
      }
      }服务端控件要刷新
     <input type="checkbox" name='ckbName' value='<%# Container.DataItem%>' /><%# Container.DataItem%>
    </ItemTemplate>
        
      protected void btn_Click(object sender, EventArgs e)
      {
      value = Request.Form["ckbName"];}
