关于DATALIST传值问题 100分,在线等
DATALIST2 是嵌套在DATALIST1里面的,用的ObjectDataSource 数据原控件,我DATALIST2的ObjectDataSource 要得到DATALIST1 里面的ID 获取方法是Control 是DATALIST1 的SelectedValue 但得不到DATALIST1里面的ID 也设了dataKey 为ID就是得不到,数据原控件得不到这个值吗?各位大侠帮忙啊 --------------------编程问答-------------------- 顶,帮忙啊,大哥们 --------------------编程问答-------------------- 1 --------------------编程问答--------------------protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Repeater wk = (Repeater)e.Item.FindControl("Repeater2");
DataRowView row = (DataRowView)e.Item.DataItem;
string pid = row["id"].ToString();
wk.DataSource =db.getDS(pid );//注意pid这里是Repeater1的主键值
wk.DataBind();
}
}
dalalist和Repeater类似，把控件名改过来就可以了 --------------------编程问答-------------------- 贴贴你的页面代码(样式都不要)，还有打算在什么事件中得到 --------------------编程问答-------------------- <td >
<asp:DataList ID="DataList1" runat="server" DataSourceID="ObjectDataSource1" DataKeyField="ID">

<asp:Label ID="IDLabel" runat="server" Text='<%# Eval("ID") %>' Visible="false" ></asp:Label><br />
