Repeater嵌套gridview

前台：
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1" OnItemDataBound="Repeater1_ItemDataBound">
<ItemTemplate>
id:<%#Eval("ID")%>
carid:<%#Eval("car_id")%>
<asp:GridView ID="inGridView" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
SortExpression="ID" />
<asp:BoundField DataField="name1" HeaderText="name1" SortExpression="name1" />
<asp:BoundField DataField="sex" HeaderText="sex" SortExpression="sex" />
<asp:BoundField DataField="qu" HeaderText="qu" SortExpression="qu" />
</Columns>
</asp:GridView>
userid:<%#Eval("userID")%>
</ItemTemplate>
</asp:Repeater>

后台：
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
GridView gridview = (GridView)e.Item.FindControl("inGridView");
DataRowView rowv = (DataRowView)e.Item.DataItem;
string id = Convert.ToString(rowv["car_id"]);//Repeater1中绑定中的数据，也即主表上和子表的关联字段
if (id != null && id != "")
{
string sqltext = "select top 5 id,name1,sex,qu from second where id='" + id + "'";
DataSet ds = datacontrol.getdatas(sqltext);//获取从数据,这里是我的数据提取类,换成你自己的数据提取方法
if (ds != null)
{
try
{
gridview.DataSource = ds;
gridview.DataBind();
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
}

}
