How to get Content Block from page - Sitefinity - Front- & Back-End Development

Hi

Am trying to write a routine that extracts content blocks from pages for the purposes of creating an XML file to feed another development.

I am stuck on the last 1%. Below is the code I have so far:

PageManager pManager = PageManager.GetManager();

ContentManager contentmanager = ContentManager.GetManager();

PageData page = null;

IQueryable<PageNode> nodes = pManager.GetPageNodes().Where(t => t.ApprovalWorkflowState == "Published");

foreach (PageNode node in nodes)

crap = "";

if (node.Page != null) str += node.Page.Id + " - ";

str += node.Title + " ";

if (node.Page != null)

page = node.Page;

//IList<PageControl> controls = page.Controls;

List<ContentBlock> blocks = page.Controls.Where(c=>c.ObjectType==typeof(ContentBlock).FullName).Cast<ContentBlock>().ToList();

foreach (ContentBlock block in blocks)

str += " " + block.Html + " ";

The issue I have is I successfully identify a PageControl as of type ContentBlock, but I cannot find a way to successfully cast or convert it to a ContentBlock. I have tried iterating through PageContol objects, above was my last attempt (which allowed me to compile) which was using "page.Controls.Where(c=>c.ObjectType==typeof

(ContentBlock).FullName).Cast<ContentBlock>().ToList()" but it fails at runtime stating it cannot cast PageControl to ContentBlock.

If anyone can help it would be much appreciated. If I can get the ContentBlock.Html value from the PageControl itself, I am not fussed, just need the data.

Thanks

Hi Michael,

You should do the following - iterate through the Controls collection of a PageData and then use pManager.LoadControl() for each control and verify the returned result with

var control = pManager.LoadControl(ctrl);
if (control is ContentBlock)
