Using document selector in transformation

I've created a new doctype with a document selector field, and I'm now trying to retrieve this data in a transformation so that I can create a link to the document the user selects. However, I can't work out what method to call in the transformation to get the full document link - everything I try leads to a 404 error.

RE:Using document selector in transformation

Hi,

You could use standard <%# GetDocumentUrl("NodeGUIDColumn", "NodeAlias") %> method. This method returns URL, that contains GUID, so from SEO point of view is better to use different approach.
I would recommend you to use following custom method in transformation. Please find more information about adding custom functions to transformation in Developer’s guide :
http://devnet.kentico.com/docs/devguide/index.html?adding_custom_functions_to_transformations.htm

public static string GUIDtoURL(object inputGUID)
{
string txtGUID = (string) inputGUID;
Guid guid = new Guid(txtGUID);
if (guid != null)
{
int nodeid = CMS.TreeEngine.TreePathUtils.GetNodeIdByNodeGUID(guid, CMS.CMSHelper.CMSContext.CurrentSite.SiteName);
CMS.TreeEngine.TreeNode node = CMS.CMSHelper.TreeHelper.SelectSingleNode(nodeid);

return CMS.CMSHelper.CMSContext.GetUrl(node.NodeAliasPath, node.DocumentUrlPath, CMS.CMSHelper.CMSContext.CurrentSiteName);
}
return "";
}

You could use following string to execute this custom method in transformation
<%# MyFunctions.GUIDtoURL(Eval("documentSelectorField")) %>

Best regards,
Michal Legen

I'm guessing it's something in the parameters, but cannot see where. Any help? Thanks, Mark


Member	kentico_michal - 1/11/2011 9:21:11 AM RE:Using document selector in transformation Hi Mark Have you tried to use following code: <a href="<%# GetDocumentUrl("DocumentSelectorField", "NodeAlias") %>" > Link</a> The prefix ~ should be replaced automatically with the domain name and the link should be generated correctly. Best regards, Michal Legen


Member	mwladika-sfopera - 1/11/2011 12:05:38 PM RE:Using document selector in transformation Hi Michal, We did try that, but that function returns a url of this format: ~/getdoc/e19b1c47-119c-4998-8b55-78a24f25a674/NodeAlias.aspx I tried playing around with the parameters, seems like the second one simply becomes the filename at the end. I cannot find any documentation on this function.

RE:Using document selector in transformation

Hi Mark

It seems to me that your output filter is disabled. So to deal with this problem, could you please try using ResolveUrl method:

<%# CMS.GlobalHelper.UrlHelper.ResolveUrl(GetDocumentUrl("DocumentSelectorField", "NodeAlias")) %>

Moreover, you are right the second parameter simply becomes the filename at the end.

Best regards,
