Question

我想访问项目的布局定义，以便我可以访问添加到项目中的渲染，然后访问附加到所述渲染的数据源。我似乎找不到办法做到这一点。我能做的最好的事情是访问__renderings字段，但后来我发现这将访问原始渲染定义项而不是存储在设计版面中的特定数据源实例。

这是Sitecore 7.5 MVC

如果有帮助，这就是我尝试做的事情：

// Get the default device
DeviceRecords devices = item.Database.Resources.Devices;
DeviceItem defaultDevice = devices.GetAll().Where(d => d.Name.ToLower() == "default").First();

// Get the rendering references for the default device
Sitecore.Data.Fields.LayoutField layoutField = item.Fields["__renderings"];
Sitecore.Layouts.RenderingReference[] renderings = layoutField.GetReferences(defaultDevice);

// Get the required renderings
RenderingItem headerRenderingItem = null;
RenderingItem aboutRenderingItem = null;

foreach (var rendering in renderings)
{
    if (rendering.Placeholder == "headerPlaceholder")
        headerRenderingItem = rendering.RenderingItem;
    else if (rendering.Placeholder == "/aboutSectionPlaceholder/textPlaceholder")
        aboutRenderingItem = rendering.RenderingItem;
}
Assert.IsNotNull(headerRenderingItem, "no header rendering item found");
        Assert.IsNotNull(aboutRenderingItem, "no about rendering item found");

// Get their datasources
ID headerDatasourceId = ID.Parse(headerRenderingItem.DataSource); // The datasource string is null as it is accessing the datasource definition item itself
ID aboutDatasourceId  = ID.Parse(aboutRenderingItem.DataSource);  // Same as above

RenderingReference.RenderingItem指的是/ layout部分中的呈现项。你可以做的是使用RenderingReference.Settings.Datasource。

所以你的代码看起来像：

foreach (var rendering in renderings)
{
    if (rendering.Placeholder == "headerPlaceholder")
        headerRenderingDatasourceId = rendering.Settings.Datasource;
    else if (rendering.Placeholder == "/aboutSectionPlaceholder/textPlaceholder")
        aboutRenderingDatasourceId = rendering.Settings.Datasource;
}

Item headerRenderingDatasourceItem;
if (!string.IsNullOrEmpty(headerRenderingDatasourceId)
    headerRenderingDatasourceItem = item.Database.GetItem(headerRenderingDatasourceId);

Sitecore以编程方式访问布局定义
