Namespace: EPiServer.DataAbstraction
Assembly: EPiServer.dll
Version: 9.12.2
Syntax
public class DynamicProperty
Remarks

EPiServer.DataAbstraction.DynamicProperty is a non-cached API for administrative purposes and should not be used on normal templates that are not for administrative purposes. Using this API on your templates will significally impact performance. The recommendation is always to read dynamic properties on PageData objects returned from the global instance of the DataFactory class, EPiServer.DataFactory.Instance.

Examples
  Example that changes the value of dynamic property "MetaKeywords" on the current page.

                DynamicProperty prop = DynamicProperty.Load(CurrentPage.PageLink, "MetaKeywords");
    prop.PropertyValue.Value = "Keyword1,Keyword2";
    prop.Save();
        Examples that outputs some debug information for the current page

            DynamicPropertyCollection props = DynamicProperty.ListForPage(CurrentPage.PageLink);
foreach (DynamicProperty prop in props)
{
    Response.Write("Property " + prop.PropertyValue.Name + " is");
    switch (prop.Status)
    {
        case DynamicPropertyStatus.Defined:
            Response.Write(" set on this page to " + prop.PropertyValue.ToString());
            break;
        case DynamicPropertyStatus.Inherited:
            Response.Write(" inherited from " + prop.InheritedPageLink.ToString() + " with value " + prop.InheritedValue.ToString());
            break;
        case DynamicPropertyStatus.Undefined:
            Response.Write(" not defined.");
            break;
        default:
            break;
    }
}
