Sitecore:如何使用codebehind中的sublayout参数? [英] Sitecore: How to use sublayout parameters from codebehind?

问题描述

如何从子布局背后代码的参数"字段(第二张屏幕截图)中获取值?

我了解，当将渲染(特别是子布局)添加到项目的演示文稿详细信息中时，我可以获取/设置参数，如此处所述(

I understand I can get/set parameters on a rendering (specifically sublayout) when it is added to the presentation details of an item, just as described here (Sitecore 6 - using parameters).

但是，我想使用布局定义项中的parameters字段.在属于布局定义的文件的代码后面，我可以将父级强制转换为子布局，并且该对象还具有.Parameters属性，但是其中不包含我期望的值.

However I would like to use the parameters field from the layout definition item. In the codebehind of the file belonging to to layout definition I can cast the parent to a sublayout and that object also has a .Parameters property, however this doesn't contain the values I'd expect.

这是背后控制代码中的Page_Load方法:

This is the Page_Load method in the control code-behind:

protected void Page_Load(object sender, EventArgs e)
{
    var sublayout = ((Sublayout)this.Parent);
    string rawParameters = Attributes["sc_parameters"];
    NameValueCollection parameters =
      Sitecore.Web.WebUtil.ParseUrlParameters(rawParameters); 
      //parameters contains values from "Additional parameters (first screenshot)

      //I do not know the sublayout item id or sublayout path, so how do I get
      //the values from the second screenshot?
}

再次检查仍然无效，仅显示additional parameters:

Doublecheck still doesn't work, only additional parameters are shown:

推荐答案

您可以获取在子布局上定义的参数，但是有点麻烦.您需要先找到正确的渲染项目，然后从那里检索参数

You can get the parameters defined on the sublayout but it's a bit long winded. You need to find the correct rendering item first and from there retrieve the parameters

   var sublayout = ((Sublayout)this.Parent);
   //Get all rendering
   var renderings = Sitecore.Context.Item.Visualization.GetRenderings(Sitecore.Context.Device, true);

   //Get the first rendering that matches the current sublayout's path
   var sublayoutRendering = renderings.FirstOrDefault(r => r.RenderingItem.InnerItem["Path"] == sublayout.Path);

   if (sublayoutRendering != null)
         Response.Write(sublayoutRendering.RenderingItem.Parameters);

您可以使用Mark的方法来获取布局详细信息"中设置的参数的参数

You can use Mark's way to get the parameters for the parameters set in the "Layout Details"

上面的解决方案可以使用，但是它非常脆弱，并且依赖于将来可能会改变的sitecore内部.我不建议您将它与生产一起使用.必须有更好的方法来实现您想要的目标.

The above solution will work but it's very fragile and depends on sitecore internals that might change in the future. I wouldn't recommend you go with it in production with it. There must be a better way to achieve what you want.
