repeater操作

protected void rpRole_ItemDataBound(object sender, RepeaterItemEventArgs e)

{

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

{

DataRowView drv = e.Item.DataItem as DataRowView;

string roleid = drv["Id"].ToString();

CheckBox chb = e.Item.FindControl("chbId") as CheckBox;

if (ht.ContainsValue(roleid))

{

chb.Checked = true;

}

}

}

--关于Repeater中嵌套Repeater写法,注意此时html生成二级Repeater的id是多个

protected void rpFn1_ItemDataBound(object sender, RepeaterItemEventArgs e)

{

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

{

DataRowView drv = e.Item.DataItem as DataRowView;

int functionId = Convert.ToInt32( drv["Id"].ToString());

Repeater rp2 = (Repeater)e.Item.FindControl("rpFn2"); --如果不这样做，就报"当前上下文中不存在名称rpFn2"

DataSet ds2 = new DataSet();

ds2 = bllF.GetList(-1, "ParentId=" + functionId, "SortBy desc");

rp2.DataSource = ds2;

rp2.DataBind();

}

}

datarow[] 绑定可以到datalist等控件

刚开始以为不可以绑定到datalist gatagrid repeater等控件 原来是不会写

DataRow[] dr=dt.Select();

DataGrid1.DataSource=dr;

DataGrid1.DataBind();

页面得写为

<asp:Label text='<%# DataBinder.eval_r(Container.DataItem,"[\"huifuName\"]")%>' Runat=server></asp:Label>

不能写为<asp:Label text='<%# DataBinder.eval_r(Container.DataItem,"huifuName")%>' Runat=server></asp:Label>

也不能写为<%# ((DataRowView)Container.DataItem["huifuName"]%>

当然一般我们使用选择都是在dataview上操作的 然后将dataview绑定到。。

rpFn1_ItemDataBound事件中不能写DataRowView drv = e.Item.DataItem as DataRowView;

要写成：DataRow drv = e.Item.DataItem as DataRow;
