I have a list that is a look up, on the lookup, it is tied to a user. In that field it has additional fields that are added to the dropdown to parse data to the list. So these are secondary items. So they appear in the list, however they do not pass the data to the form. Can someone assist in providing an example? I added an image to show what is passed.

推荐答案

我们可以使用C#代码将查找附加字段添加到列表中，然后它将以列表形式出现:

We can add the lookup additional fields to the list using C# code, then it will appear in the list form:

string mainListName = "Countries"; //Name of Lookup List
string lookupListName = "Application"; //Name of Main List Needs to add additional field to lookup
string lookupColAdditionalFieldDisplayName = "CountryCode"; //Display name of additional field in main list
string pLookupKeyName = "CountryTitle"; //Name of parent lookup field in main List
string additionalLookupFieldName = "Code"; //Name of additional Field in lookup list
//Main List
SPList mainlst = w.Lists[lookupListName];

//Lookup List
SPList lookuplst = w.Lists[mainListName];

//Main List Fields
SPFieldCollection col = mainlst.Fields;

//Lookup Primary Key
SPFieldLookup spPrimaryField = ((SPFieldLookup)col[pLookupKeyName]);

//Create Additional Field its name in lookup Field1 with display name in list TestDisplayName
SPFieldLookup field = (SPFieldLookup)mainlst.Fields.CreateNewField(SPFieldType.Lookup.ToString(), lookupColAdditionalFieldDisplayName);
field.LookupList = spPrimaryField.LookupList;
field.LookupWebId = spPrimaryField.LookupWebId;
field.LookupField = additionalLookupFieldName;
field.PrimaryFieldId = spPrimaryField.Id.ToString();
field.ReadOnlyField = true;
field.AllowMultipleValues = spPrimaryField.AllowMultipleValues;
field.UnlimitedLengthInDocumentLibrary = spPrimaryField.UnlimitedLengthInDocumentLibrary;
field.Direction = spPrimaryField.Direction;
SPAddFieldOptions op = SPAddFieldOptions.Default;

//Add Additional Field to main list
mainlst.Fields.AddFieldAsXml(field.SchemaXml, true, op);
