Programatically add a drop down list data type and prevalues?
Hi I was wondering how to add a new drop down list data type and prevalues to a document type programatically..
We used to use something like so:
var ddl = new DataTypeDefinition(-1, controlGuid);
ddl.DatabaseType = DataTypeDatabaseType.Ntext;
ddl.Key = Guid.NewGuid();
ddl.Name = name;
ServiceContext.DataTypeService.Save(ddl);
foreach (var value in preValues)
{
var p = new umbraco.cms.businesslogic.datatype.PreValue(0, 0, value);
p.DataTypeId = ddl.Id;
p.Save();
}
return ddl;
But this isn't working in the latest version of umbraco and datatypedefinitions are now slated to be deprecated?
I'm sure you've fixed this now, but for current readers, I wrote a helper function to merge prevalues in bulk so I could provide lookup editing for a client on drop down lists. If you needed replace/delete functionality then it'd be easy to add, I just haven't done it yet :)
This uses all current, non-deprecated functions.
Requires:
using UC = Umbraco.Core;
Code:
/// <summary>
/// Merges new prevalues to an existing datatype.
/// For dictionary based prevalues, you must provide a dictionary key to merge with. For simple DropdownLists etc this is the same as the label
/// For array based prevalues, it merges based on the actual value, NOT the id
/// </summary>
public static MergePreValueResult MergePreValues(UC.Models.PropertyType propertytype, List<string> arrayvalues = null, IDictionary<string, string> dictionaryvalues = null)
{
MergePreValueResult res = new MergePreValueResult();
UC.Services.IDataTypeService datatypeservice = UC.ApplicationContext.Current.Services.DataTypeService;
UC.Models.IDataTypeDefinition datatypedef = datatypeservice.GetDataTypeDefinitionById(propertytype.DataTypeDefinitionId);
if (datatypedef != null)
{
Dictionary<string, UC.Models.PreValue> final = new Dictionary<string, UC.Models.PreValue>();
UC.Models.PreValueCollection currentprevalues = datatypeservice.GetPreValuesCollectionByDataTypeId(propertytype.DataTypeDefinitionId);
if (currentprevalues != null)
{
res.Success = true;
UC.Models.PreValue prevalue = null;
res.IsDictionary = currentprevalues.IsDictionaryBased;
if (currentprevalues.IsDictionaryBased && dictionaryvalues != null)
{
foreach (KeyValuePair<string, string> kp in dictionaryvalues.Union(currentprevalues.PreValuesAsDictionary.ToDictionary(xk => xk.Key, xv => xv.Value.Value)))
{
if (currentprevalues.PreValuesAsDictionary.ContainsKey(kp.Key))
{
prevalue = currentprevalues.PreValuesAsDictionary[kp.Key];
prevalue.Value = kp.Value;
res.Updated++;
}
else
{
prevalue = new UC.Models.PreValue(kp.Value);
res.Created++;
}
final.Add(kp.Key, prevalue);
}
}
else if (!currentprevalues.IsDictionaryBased && arrayvalues != null)
{
foreach (string value in arrayvalues.Union(currentprevalues.PreValuesAsArray.Select(x => x.Value)))
{
prevalue = currentprevalues.PreValuesAsArray.FirstOrDefault(x => x.Value == value);
if (prevalue != null)
{
prevalue.Value = value;
res.Updated++;
}
else
{
prevalue = new UC.Models.PreValue(value);
res.Created++;
}
final.Add(null, prevalue);
}
}
}
datatypeservice.SaveDataTypeAndPreValues(datatypedef, final);
}
return res;
}
