ComboBox doesn't save selected item sharepoint list

[miquilenadiego]

Hello People!

I'm new on powerapps, I'm working with basic sharepoint list for a company project. 

I don't know what I'm doing wrong but I can't save the value selected in a combobox.

This is the situation:

List "buscar" contains a lookup field called "lukop" pointing to the colum 'infolease' in the list "concesionarios"

I inserted the combobox control in the "buscar" SPList inside the "lukop" datacard and set combobox.Items = concesionarios.infolease. Meanwhile I set lukop_datacard1.update = ComboBox2.Selected

I saved and published, when I use the combo to add a new item it works but it doesn't store the value, when I edit it doesn't stores it either.

What am I missing?

Hello @v-xida-msft I sent you a message 3 days ago but for some reason the system told me that it needed moderation first (I didn't tell you something aggressive btw haha) In that moment I couldn't make work your solution but it was because i was making the same mistake as with mdevaney solution, I wasn't using the curly brackets because I thought they were there because of the code format of the forum and not a part of the code itself. 

I tried it yesterday including the curly braces and now it works! Than you very much for your help, I marked your answer as a solution as well.

When changing the Items property of the ComboBox the isSearchable field will sometimes get set to false by PowerApps Studio automatically.  Its kind of an annoying feature if you ask me.

Now that we've solved the problem I will tell you a little bit more about this code.  LookUps are a "complex" column type in SharePoint.  This means the column stores more than a single value (like a text or number column would).  Here you can see 3 values: #1 the connector type #2 the unique SharePoint ID identifying the record and #3 the Value to be displayed.

{
    '@odata.type':"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference", 
    Id:Text(ComboBox_lokup.Selected.ID,"[$-en-US]0"),
    Value:ComboBox_lokup.Selected.ID
}
