Sharepoint PeopleEditor: How do I know which type of user / group is returning?

Question

I have PeopleEditor:

<SharePoint:PeopleEditor ID="peopleEdit" ... SelectionSet="User,DL,SecGroup,SPGroup" /> 

It works flawlessly on the page, that is, I can select AD users, Sharepoint groups and everything that I would like.

The problem is that I cannot find the property in PeopleEditor which type of user / group will be returned . Take the following example:

 //User: John Doe - mycompany\jondoe is at position 0 //Sharepoint group: "All Site Users" is at position 1 PickerEntity pickerEntity1 = (PickerEntity).peopleEdit.ResolvedEntities[1]; // pickerEntity1.Key = "All Site Users" // pickerEntity1.Claim = null // pickerEntity1.DisplayText = "All Site Users" PickerEntity pickerEntity0 = (PickerEntity).peopleEdit.ResolvedEntities[0]; // pickerEntity1.Key = "mycompany\jondoe" // pickerEntity1.Claim = null // pickerEntity1.DisplayText = "Doe, John" 

I can do some “hacker” things, for example, try to pass the value of the returned string [sic] as a user or as a group and execute some program flow based on an exception (if the user exists, otherwise, if the group exists, etc. .), but I would not consider this clean code.

Is there a better way to select people / groups in Sharepoint or a better way to work with PeopleEditor?

Answer 1

Use the PrincipalType value from the EntityData hash table:

 string principalType = pickerEntity1.EntityData["PrincipalType"].ToString(); 

I do not remember all the possible values, but User and SharePointGroup definitely among them.

To list all the information that this object has, an EntityDataElements array EntityDataElements useful. For SPGroup this contains SPGroupID , AccountName , PrincipalType .

Maybe it contains values ​​from Microsoft.SharePoint.Utilities.SPPrincipalType enum, but I have not tested it.

Here you go:

 [Flags] public enum SPPrincipalType { None = , User = 1, DistributionList = 2, SecurityGroup = 4, SharePointGroup = 8, All = SharePointGroup | SecurityGroup | DistributionList | User, }
