    How to get Pre-Value ID's rather than String Names

    Hello,

    I'm trying to find out how to find the Id of a pre-value list selection (in this case a check box list).

    • Id: 1 Value: United Kingdom
    • Id: 2 Value: United States
    • Id: 3 Value: The Netherlands

    I have the check box list (added via contour), which returns the users selection as United Kingdom, United States however I need to find the Id's of the selection, rather than the names.

    I sort of need the reverse of GetPreValueAsString().

    I hope this makes sense and can anyone help.

    Thanks

    Paul

    While a little bit crude, I have found a way to do this.

    selectedFileCategories is my comma seperated string e.g. United Kingdom, United States

                    XPathNodeIterator preValueRootElementIterator = umbraco.library.GetPreValues(1361);
                preValueRootElementIterator.MoveNext();

                XPathNodeIterator preValueIterator = preValueRootElementIterator.Current.SelectChildren("preValue", "");

                while (preValueIterator.MoveNext())
                {
                    if (selectedFileCategories.Contains(preValueIterator.Current.Value))
                    {
                        selectCats += preValueIterator.Current.GetAttribute("id", "") + ",";
                    }
                }

    This will return selectCats as 1,2,3
