Create new SP list item including value in lookup column

Posted on by StigMil

I want to create an attendance register for a music group. I have a Sharepoint list "Current members" - each item is a unique member of the group, with columns including name, address plus a unique ID column. I have a second Sharepoint List "Rehearsal attendance" where each item includes columns "Rehearsal date", a lookup column ("Member") that links back to the "Current members" list and a Yes/No column "Attended". I want to be able to create a new item in the "Rehearsal attendance" list for every member for every rehearsal date, to show whether a group member attended a particular rehearsal.

On one screen I have a Gallery to browse the "Current members" list. I want to select a member from the Gallery and populate an Edit Form (in New mode) to create a new item in the "Rehearsal attendance" list, with default values: "Rehearsal date" is today(), "Member" is the member selected from the Gallery (lookup) and "Attended" is true.

How can I set the default value of the Edit Form control for the "Member" lookup to be the correct lookup value for the member selected in the Gallery? Thanks for any ideas/links to documentation.

Hi @StigMil ,

Firstly please ask yourself why you need to use the Lookup type column when you can do the same thing in Power Apps without all the unnecessary complications and restrictions - I have a blog on data structure that may assist.

However to answer your question, if this is a Combo Box (you did not specify) you need to refer to the valid output in the DefaultSelecteditems. So if it was (I am only guessing the value as you have not provided the Items)

ComboBoxName.Selected.Member

it would be

{Value:ComboBoxName.Selected.Member}

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

Hi @StigMil ,

So you are selecting from the members Gallery and navigate to the NewForm which links to the other list as data source, the Member column is a LookUp column in the Rehearsal attendance list so in the Form there should be a MemberDataCard contains a DataCardValue which is a Combobox, with Items property

Choices('Rehearsal attendance'.Member)

Since you would like to auto-populate the Combobox with the member selected in the Gallery, you will need to use the LookUp function:

LookUp(Choices('Rehearsal attendance'.Member), Value = Gallery.Selected.Name)

Besides, you could save the selected member name in a variable OnSelect of the arrow icon in the Gallery:

Set(varName, ThisItem.Name)

Then the formula for DefaultSelectedItems of the Combo box will be:

LookUp(Choices('Rehearsal attendance'.Member), Value = varName)

Hope this helps.
