Need urgently help with Receiving Servers Categories list

I'm looking for a way to use a web service to get the category list on the server.

i need to show the categories names in a asp.net dropdownlistbox (c#).

After selecting a category ,i want to show in a table a list of its properties and allow the user to upload a new document that contains these properties.

i need help with:

getting the category list by name and i.
get the selected category attributes and show it in a table or grid, this will alow the user to upload a new document to the selected folder and edit its attributes before uploading.

i couldn't find in the forum an example in c# or any other language for that matter.

Could this be what you are looking for ?

getAttributeGroups

public AttributeGroup[] getAttributeGroups()

Gets the array of AttributeGroup objects which represent Category instances or other metadata

Sorry I have not yet ventured into websvcs but looked like this would give you the cat/atts of the system

Is it possible to get an example of this? I am also trying to retrieve a list of the categories defined on a system.

Hi Kobi,

I'm not sure I completely understand what you are trying to do. Do you want to get a list of all the categories that have been created in any location? If so you'll likely need to use the Search Service. There is a sample posted at the top of this forum for using the Search Service.

If you are just looking for the categories in the Categories Workspace you could use the Document Management Service. To get the Categories Workspace node you can use the DocumentManagement.GetRootNode() method and pass in "CategoriesWS" as the root type. Once you have that you just need to list the children in that container.

After you get the IDs for all the categories you can use the DocumentManagement.GetCategoryDefinition() method to get the definition of a single category or if you want the definition of a list of categories you can use the DocumentManagement.GetCategoryDefinitions() method.

Hope this helps.

hi,

i was able to upload the file and get the folder attributes after attaching a category to a folder.

my problem now is that when I'm trying to upload a new file to a folder with category and attributes using code i get this error MSG:

Error: The content type text/html of the response message does not match the content type of the binding (multipart/related; type="application/xop+xml"). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response were: '

how can i solve this,the problem is probably with the Meta data obj I'm uploading using this row of code:

docContext = dm.CreateDocumentContext(dmOTAuth, parentID, name, comment, advancedVersionControl, docMetadata);

my code is this:

Metadata docMetadata = new Metadata();
                AttributeGroup[] attributeGroups1 = new AttributeGroup[1];
                DataValue[] attrItems = new DataValue[2];
                attrItems[0] = new DataValue();
                attrItems[1] = new DataValue();
                attributeGroups1[0] = new AttributeGroup();
                attrItems[0].Description = "a1";
                attrItems[1].Description = "a2";
                attributeGroups1[0].Values = attrItems;
                docMetadata.AttributeGroups = attributeGroups1;

please advise...i'm Desperate.
