c# - 简单的 Sitecore ASP 转发器 - 访问字段

Question

我这里有一个非常基本的 sitecore 问题。我想遍历一组子对象(位置)，并显示有关每个子对象的一些信息。

我正在使用 ASP 转发器进行迭代，我正在加载页面上的 child ，我正在尝试使用 sc 标签来显示信息 - 但我没有出现在页面上。

谁能帮我看看我在这里遗漏了什么？

代码隐藏:

protected void Page_Load(object sender, EventArgs e)
    {
        var item = Sitecore.Context.Item;

        var children = new List<Sitecore.Data.Items.Item>();
        foreach (var child in item.GetChildren())
        {
            children.Add((Sitecore.Data.Items.Item)child);
        }

        LocationsRpt.DataSource = children;
        LocationsRpt.DataBind();
    }

标记:

<asp:Repeater runat="server" ID="LocationsRpt" OnItemDataBound="LocationsRptItemDataBound">
    <ItemTemplate>
        <div class="InnerContentSec clearfix">
            <div id="AboutSolar" class="AboutSolar clearfix">
                <div class="items">
                <h3>
                    <sc:Text runat="server" ID="Title"/>
                </h3>
                <div class="LocationBlock clearfix">
                <div class="ImgSec">
                    <sc:Image id="Image" runat="server" Width="185" Height="107" />
                </div>
                <div class="DescSec">
                    <p><sc:Text ID="ShortDescription" runat="server" /></p>
                </div>
                </div>
                </div>
            </div>
        </div>
    </ItemTemplate>
</asp:Repeater>

最后是 DataItemBound

protected void LocationsRptItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            var subItem = e.Item.DataItem as Item;  

            if (subItem != null)
            {
                var appTitle = e.Item.FindControl("Title") as Sitecore.Web.UI.WebControls.Text;

                if (appTitle != null)
                {
                    appTitle.DataSource = subItem.ID.ToString();
                    appTitle.Field = "Application Title";
                    appTitle.DataBind();
                }

                var appImage = e.Item.FindControl("Image") as Sitecore.Web.UI.WebControls.Image;

                if (appImage != null)
                {
                    appImage.DataSource = subItem.ID.ToString();
                    appImage.Field = "Location Image";
                    appImage.DataBind();
                }

                var shortDescription = e.Item.FindControl("ShortDescription") as Sitecore.Web.UI.WebControls.Text;

                if (shortDescription != null)
                {
                    shortDescription.DataSource = subItem.ID.ToString();
                    shortDescription.Field = "Short Description";
                    shortDescription.DataBind();
                }
            }
        }
    }

Answer 1

你也可以这样做:

页面加载:

protected void Page_Load(object sender, EventArgs e)
{
    LocationsRpt.DataSource = Sitecore.Context.Item.GetChildren();
    LocationsRpt.DataBind();
}

标记:

<asp:Repeater runat="server" ID="LocationsRpt">
    <ItemTemplate>
        <div class="InnerContentSec clearfix">
            <div id="AboutSolar" class="AboutSolar clearfix">
                <div class="items">
                <h3>
                    <sc:Text runat="server" ID="Title" Item="<%# Container.DataItem %>"/>
                </h3>
                <div class="LocationBlock clearfix">
                <div class="ImgSec">
                    <sc:Image id="Image" runat="server" Width="185" Height="107"  Item="<%# Container.DataItem %>" />
                </div>
                <div class="DescSec">
                    <p><sc:Text ID="ShortDescription" runat="server"  Item="<%# Container.DataItem %>" /></p>
                </div>
                </div>
                </div>
            </div>
        </div>
    </ItemTemplate>
</asp:Repeater>

在这种情况下，您不需要数据绑定(bind)事件。
