关于Repeater 的三层嵌套问题 感兴趣的哥哥姐姐请看看！！
///第一层
<asp:Repeater ID="RpData" runat="server" OnItemDataBound="RpData_ItemDataBound">
<ItemTemplate>
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="20px">
<div style="height: 10px;">
</div>
<div>
<span style="word-wrap: break-word; word-break: nomal; font-size: 13px; font-weight: bold;">
<%# Eval("Name")%></span></div>
<asp:HiddenField ID="PowerID" Value='<%# Eval("ID") %>' runat="server" />
</td>
<td>
<div style="width: 800px; float: left; margin-left: -10px;">
///第二层
<asp:Repeater ID="RpUpid" OnItemDataBound="RpUpid_ItemDataBound" runat="server">
<ItemTemplate>
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="20px">
<div style="height: 10px;">
</div>
<div>
<span style="word-wrap: break-word; word-break: nomal; font-size: 13px; font-weight: bold;">
<%# Eval("Name")%></span></div>
<asp:HiddenField ID="upid" Value='<%# Eval("ID") %>' runat="server" />
</td>

///////第三层

第一层主要读出父类标题
第二层包括子类标题+第三层Repeater（需要判断 无子类标题的 第三层Repeater 直接按照父类ID读数据 这是最蛋疼的）
第三层 根据子类ID 读数据 子类ID>1个
表中有标识 upid 父类=0 子类=父类ID 这样
cs代码
public new void DataBind()
{
DataSet ds = new DataSet();
ds = objPr.GetList(" upid = 0 Order by Sort");
RpData.DataSource = ds.Tables[0];
RpData.DataBind();
}
protected void RpData_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
HiddenField PowerID = (HiddenField)e.Item.FindControl("PowerID");
DataSet ds = null;
if (PowerID.Value == "4")
{
ds = objPr.GetList("upid<>0 order by sort");
Repeater RpUpid = (Repeater)e.Item.FindControl("RpUpid");
RpUpid.DataSource = ds.Tables[0];
RpUpid.DataBind();
}
//else
//{
// ds = objPr.GetList("upid = 0 order by sort");
//}
}
}
protected void RpUpid_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
DataSet ds = null;
HiddenField PowerID = (HiddenField)e.Item.FindControl("upid");
//if (pid != 4)
//{
// ds = objUser.GetJoinList(0, "a.PowerID = " + pid, "");
//}
//else
//{
ds = objUser.GetJoinList(0, "a.PowerID = " + PowerID.Value, "");
//}
DataTable newdtb = new DataTable();
newdtb.Columns.Add("ID", typeof(int));
newdtb.Columns.Add("Name", typeof(string));
newdtb.Columns.Add("Number", typeof(int));
newdtb.Columns.Add("UserID", typeof(int));
newdtb.Columns["ID"].AutoIncrement = true;
if (ds.Tables[0].Rows.Count > 0)
{
foreach (DataRow Dr in ds.Tables[0].Rows)
{
DataRow newRow = newdtb.NewRow();
newRow["Name"] = Dr["Name"];
newRow["UserID"] = Dr["ID"];
int Number = objM.GetNotReadCount(Convert.ToInt32(Dr["ID"]));
newRow["Number"] = Number;
newdtb.Rows.Add(newRow);
}
}
Repeater RpUser = (Repeater)e.Item.FindControl("RpUser");
RpUser.DataSource = newdtb;
RpUser.DataBind();
pid = 0;
}
}
不知道怎么去判断 在第一层的类里如何绑定第三层 在第二层如何获取第一层的隐藏域值
[解决办法]
+qq一起讨论
