Hi Anton,

This depends on which datatype you are using.  Most datatypes that allow the user to select multiple values store them either in CSV or XML format.  Or are you actually wanting to retrieve the possible "prevalues" (ie for the Dropdown datatype)?  Which datatype are you using?

-Tom

My own datatype, Render Control: Dropdown list. With database datatype Ntext

Hi,

Here's one way to get all the prevalues of your datatype:  GetPreValues

Here's another way:

            var prevalues = umbraco.cms.businesslogic.datatype.PreValues.GetPreValues(1132);
            IDictionaryEnumerator ide = prevalues.GetEnumerator();
            while (ide.MoveNext())
            {
                PreValue pv = (PreValue)ide.Value;
                Literal1.Text += pv.Value + "<br/>";
            }

HTH,
Tom

Hi, thanks. And how I can set values? I can create new node, but I dont now how set values in my data type by API.

Is this the same question as your other thread?  I think the problem was you need to set it to the ID of the prevalue rather than the text value of it.  In the above code you could get that from pv.Id

-Tom

Yes it is the same  question.

Yep, in that case see what I said above - instead of setting it to "US" you need to set it to the ID of the Prevalue with the Value of "US".

You could get the ID by writing a quick method to enumerate through the prevalues using the above code and find the one you're looking for and grab it's ID.

-Tom

doc.getProperty(" MY_Dropdown_list_datatype").Id = 18;

'umbraco.cms.businesslogic.property.Property.Id' -- Read only

It is work!!!!!!

doc.getProperty(" MY_Dropdown_list_datatype").Value = "18";

Thank you Tom, very much!
