Setting DefaultSelectedItems of ComboBox to work like Dropdown

Hello,

 

I have a (functioning) PowerApps form pointing to SQL Server.  One of the fields is a dropdown box where, if it is a new records, displays "...Select a value" and, if modifying a record, shows the currently saved record.  This works fine:

 

DEFAULT: If(EditForm_InvestmentChecklist.Mode=New, "...Select a value", ThisItem.LGL_InvestmentChecklist_InvestmentName)

 

But, the users want to be able to search/filter the dropdown results so it appears I need to use a combobox.  The DEFAULT calc above does not work in the combobox.  Have also tried moving this to DEFAULTSELECTEDITEMS and that doesn't work either.  I have 'Allow Multiple Selections' = False.  Can only have 1 value selected.

Any assistance appreciated.

Thanks,

Dan

Hi @lesotho_kid ,

Try this in the DefaultSelectedItems

{Value:ThisItem.LGL_InvestmentChecklist_InvestmentName}

or

{LGL_InvestmentChecklist_InvestmentName:ThisItem.LGL_InvestmentChecklist_InvestmentName}

Hi @lesotho_kid ,

 

What is the Items property of combobox?

 

The DEFAULTSELECTEDITEMS  property should be a record retrieved from the combobox Items, so try with LookUp function.

For example, If the combobox items property is Accounts, and want Tom to be the Default selection, the DEFAULTSELECTEDITEMS property should be like this:

LookUp(Accounts, 'Account Name'="Tom")

So in your case, the code synatx:

If(
EditForm_InvestmentChecklist.Mode=FormMode.New,
LookUp(ItemsProperty,'The Column' = "...Select a value"),
LookUp(ItemsProperty,'The Column' = ThisItem.LGL_InvestmentChecklist_InvestmentName)
)

Hope this helps.

Thanks @WarrenBelz 

That worked - just had to add the if statement.  And need to review how/why the curly brackets were needed.   Is there a special term to read about - some sort of array or something like that?  Assuming it is related to the multiple item option.

 

This was the final answer:

If(EditForm_InvestmentChecklist.Mode=New,{Value:"...Select a value"}, {Value:ThisItem.LGL_InvestmentChecklist_InvestmentName})
