How to set default value for combo box with user name

[Voltes]

Hi guys,

How to give default value to a ComboBox with current user name ?

I tried to put in property Default or DefaultSelectedItem but returned error. I'm using User().Fullname

In Items property I already have this : Office365Users.SearchUser({searchTerm:MyComboBoxName.SearchText}), this is so that when we type in my combo box, it is automatically filter the list. But I need to be filled in by current user name at first.

I found this thread : https://powerusers.microsoft.com/t5/Building-Power-Apps/Default-value-of-combo-box/m-p/298441#M85966

but to me it is hard to understand why ?

Thanks,

You should be able to just copy and paste this code into the DefaultSelectedItems property of your ComboBox and have it work.

If(Form1.Mode=FormMode.New,
    { 
      DisplayName:User().FullName,
      Claims:"i:0#.f|membership|" & Lower(User().Email), 
      Department:"", 
      Email:User().Email, 
      JobTitle:"", 
      Picture:""
    },
    ThisItem.YOURFIELDNAME
)

Hi @mdevaney 

Yes, it works. Much appreciated if you can tell me just a little, what is the meaning of that code ?

I've put the 1st line only actually, since I thought I only need the name in that box. Will that make the code invalid or missed its purpose ? 

So, it is like this:

Thanks again.

Yes of course.  This is the most important section of my code.

{ 
    DisplayName:User().FullName,
    Claims:"i:0#.f|membership|" & Lower(User().Email), 
    Department:"", 
    Email:User().Email, 
    JobTitle:"", 
    Picture:""
}

 
A person field in SharePoint is known as a complex column type.  This means it stores more than one piece of data about a person.  In fact it stores several! 

• DisplayName: Office 365 display name
• Claims: a unique identifier that represents a specific user
• Email: the user's email etc.
• Picture: Office 365 user photo
• etc, etc, etc.

So when we want to display a person in a new Power Apps form we must build the person object from scratch.  That's why we need all of that code inside the { } brackets. 

I would suggest you copy my code entirely.  At the very least you must have these fields: Claims, DisplayName, Email.

Just an FYI that square brackets are needed in this code in addition to the curly ones (at least for me).

If(Form1.Mode=FormMode.New,
  [{
    DisplayName:User().FullName,
    Claims:"i:0#.f|membership|" & Lower(User().Email), Department:"",
    Email:User().Email,
    JobTitle:"", Picture:""
  }],
[ThisItem.YOURFIELDNAME]
)
