Question

Can any one tell me if I can use a ASP Control instead of Field Renderer to display the field.Please see below illustration. Note:I need to do it in the Item Databound Event of Repeater.

我有一个模板, 显示字段为外部链接。例如 : 联系美国。在页面中显示该链接的一个方法就是使用下面的字段创建器。

联系人US. aspx :

<asp:Repeater ID="rptContactUS" runat="server" OnItemDataBound="Menu_OnItemDataBound">
        <ItemTemplate>
           <item><sc:FieldRenderer ID="frContactUS" runat="server"/></item>                                           
       </ItemTemplate>    
 </asp:Repeater>

联系人US.aspx.cs:

protected void Menu_OnItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        Field item = (Field)e.Item.DataItem;
        if (item != null)
        {
            FieldRenderer frContactUS= (FieldRenderer)e.Item.FindControl("frContactUS");
            if (frContactUS!= null)
            {
                frContactUS.FieldName = item.Name;
            }
        }    
    }

上述代码运作正常。我的问题是, 我是否可以使用 Asp 控制来代替 FieldRenderer, 并且将链接的链接值从 Field 项指定为 asp href 属性, 在项目中包含数据的事件中, 中继器中的链接属性。如果是, 请告诉我如何?

Thanks, Suhas

Yes you can. From what I see in your example you are binding Field to the Menu. You could also bind a List of Items to your menu. You can then retrieve the item s fields in the repeater like this:

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Item dataItem = (Item)e.Item.DataItem;
                    System.Web.UI.WebControls.HyperLink hl = (System.Web.UI.WebControls.HyperLink)e.Item.FindControl("hl");

                    if (hl != null)
                    {
                    Sitecore.Data.Fields.LinkField url = dataItem.Fields["linkfield"];

                    if (url != null)
                    {
                        hlMerk.NavigateUrl = url.Url;
                        hlMerk.Target = url.Target;
                        // more properties are available check sitecore documentation
                    时 时                       
                时 时
           时 时

时时

From here you will have the url field (obviously you should give the correct field name instead of url. The LinkField has several properties as described in the general Sitecore documentation that can be found @ http://sdn.sitecore.net.
