Question

I want to add multiple values for same managed metatag using clientobjectmodel. Anybody has ides? Iam able to add single value. This metatag is defined as Allow Multiple values.

 

Answer 1

Hi,

For example you have following terms: "Word", "Excel", "Visio" and your multiple managed metadata column name is "MyTag". So the code can be like as follows:

 

List<string> termValues = new List<string>();
termValues.Add("9;#Word|bbf906b2-4d4c-457a-93bf-c11438dd3f81");
termValues.Add("7;#Excel|bb9ff0f5-5e0f-4b4b-9c63-148ee8e44205");
termValues.Add("6;#Visio|023fa51d-5837-405b-8a7c-f430f2889242");
listItem["MyTag"] = termValues;
listItem["MyTagTaxHTField0"] = "9;#Word|bbf906b2-4d4c-457a-93bf-c11438dd3f81;7;#Excel|bb9ff0f5-5e0f-4b4b-9c63-148ee8e44205;6;#Visio|023fa51d-5837-405b-8a7c-f430f2889242";
listItem.Update();
clientContext.ExecuteQuery();

 

where WssId and termGUID you can get as you do for single managed metadata.

Hello Dmitry,

Thanks a lot for your reply - really helped a lot. However - I do still have some problems with your above example. Are there any Sharepoint settings that need to be set for this to work? For example I had to change the columndefinition of my equivalent of MyTagTagHTField0 (in my case its name is just a guid) via Sharepoint Manager.
In my environment updates won't throw errors, but I don't see Terms in Sharepoint unless I save the item once inside Sharepoint...It's working well with just one term (but in this case I don't need to update MyTagTaxHTField0 as well).

I'd really appreciate your help or any hints you could provide!

Thanks a lot, Klaus

Hello Dmitry

From where did you get the ids 9, 7, 6 are they random ? it is the peice missing in my code here si what I wrote :

          

    private void SetTaxonomyFieldMulti (string siteUrl, List CurrentList, ListItem listItem, Field field, string fieldValue)
        {

            string termValueTaxHTField = String.Empty;
            List<String> termValues = new List<string>();
            List<String> termValueNotes = new List<string>();

            if (String.IsNullOrEmpty(fieldValue) || String.IsNullOrWhiteSpace(fieldValue)) return;

            fieldValue = fieldValue.Trim();

            string[] values = fieldValue.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);

            int index = 1;
            foreach (string value in values)
            {
                string term = value.Trim();
                string termId = GetTermId(siteUrl, field, value);

                if (!String.IsNullOrEmpty(termId))
                {
                    termValues.Add(String.Format(@"{0};#{1}|{2}", index, term, termId));
                    termValueNotes.Add(String.Format(@"{0};#{1}|{2}", index, term, termId));
                }
                index++;
            }

            for (int i = 0; i < termValueNotes.Count; i++)
            {
                termValueTaxHTField += termValueNotes[i];
                if (i < termValueNotes.Count - 1)
                {
                    termValueTaxHTField += ";";
                }
            }

        
                listItem[field.InternalName] = termValues;
                listItem[field.InternalName + "TaxHTField0"] = termValueTaxHTField;
      
         }

     Thanks
