我使用此http://blogs.msdn.com/b/mikeormond/archive/2008/07/26/dynamically-loading-listview-templates.aspx文章作为动态加载模板的示例(来自.ascx文件)。
这是作者代码:
protected void Page_Load(object sender, EventArgs e)
{
ListView1.LayoutCreated += new EventHandler(ListView1_LayoutCreated);
ListView1.LayoutTemplate = LoadTemplate("LayoutTemplate.ascx");
ListView1.ItemTemplate = LoadTemplate("ItemTemplate.ascx");
}
void ListView1_LayoutCreated(object sender, EventArgs e)
{
//remove the layout template
ListView1.Controls.RemoveAt(0);
//recreate it
Control newLayoutContainer = new Control();
ListView1.LayoutTemplate.InstantiateIn(newLayoutContainer);
var userControl = newLayoutContainer.Controls[0];
userControl.ID = "MyLayout";
ListView1.Controls.Add(newLayoutContainer);
}
它给出错误:
必须在ListView的“ListView1”上定义ItemTemplate。
回发后。
怎么了?每次回发时都应该创建ListView(http://forums.asp.net/p/1305569/2558209.aspx)吗?
答案 0 :(得分:4)
要解决您的问题,请执行以下操作:
<script runat="server">
protected void ListView_Init(object sender, EventArgs e)
{
ListView1.ItemTemplate = LoadTemplate("ItemTemplate2.ascx");
}
</script>
<asp:ListView .... OnInit="ListView_Init">
