1.前置部分

<asp:Repeater ID="rptPlanNo" runat="server" OnItemDataBound="rptPlanNo_ItemDataBound">         <ItemTemplate>                   <asp:CheckBox ID="cb" runat="server" />         </ItemTemplate> </asp:Repeater>

2.1后置代码的数据绑定部分

protected void dplType_SelectedIndexChanged(object sender, EventArgs e){   //......   List<PlanNo_Generated_DistributeEntity> list = dal.GetAll(parms, "Id", 30, 0, out recordCount);//30表示控制每次派发个数   rptPlanNo.DataSource = list;   rptPlanNo.DataBind();}

2.2在绑定Repeater时,怎样拿到ItemTemplate中的asp:CheckBox,并且取得绑定的数据项,如这里的PlanNo_Generated_DistributeEntity

protected void rptPlanNo_ItemDataBound(object sender, RepeaterItemEventArgs e){   if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)   {       PlanNo_Generated_DistributeEntity entity = e.Item.DataItem as PlanNo_Generated_DistributeEntity;       CheckBox check = e.Item.FindControl("cb") as CheckBox;       check.Text = entity.Plan_No;   }}

2.3 在提交时,怎样取得ItemTemplate中的asp:CheckBox

protected void btnSendPlanNo_Click(object sender, EventArgs e){   //....   foreach (Control c in this.rptPlanNo.Controls)   {       CheckBox cbx = (CheckBox)c.FindControl("cb");       if (cbx != null)       {           if (cbx.Checked == true)           {               entity.Plan_No =  cbx.Text;               //....           }       }   }}
