Combobox search not working with DefaultSelectedItems

[christianfntn]

Just to share this, since I find the solution assembling different ideas from other posts, but not for this particular "problem".

I have a form with many Combobox, which does not allow multiple selection from a list of items. Search is enabled.

On opening, the combobox must display the default value saved on the server, and must allow user to change selection or make one if by default the data is blank.

Do not forget to put your default tiems in DefaultSelectedItems instead of Default. So in my case [Parent.Default].

The problem is if there is something in DefaultSelectedItems, search is not working. Example if the box is blank and I click on it and start typing, the list will not reduce to the corresponding items.

To avoid this, DefaultSelectedItems must be set to If(IsBlank(Parent.Default)=true;[];[Parent.Default]).

Now search will operate if the box is empty.

Please comment if something is wrong.

Hi @christianfntn,

Which data type column does the Combo box control connect to? Person column, Lookup column or Choice type column?

I have made a test on my side, and don't have the issue that you mentioned. I think there is something wrong with the formula that you provided within the DefaultSelectedItems property of the Combo box control.

More details about setting a default value for a Combo box control (connect to Person column, Lookup column or Choice type column), please check the following blog and thread:

The combobox connect to a lookup columns. 

I just started from scratch on a new app and did not experience this issue.

I came back to my app set DefaultSelectedItems back to [Parent.Default] and the search works. 

So I must agree with you something else is causing this. I'll investigate and come back if necessary.

Thanks for the complete answer and sorry for the bothering.

@TopShelf-MSFT,

listbox default select

ComboBox with multi select

Items: Distinct(Filter(Product,Name.Id=Dropdown.Selected.ID),Title)

ListBox

Items: Distinct(Filter(product,Title in Listbox.SelectedItems),Description)

Default:LookUp(Product,Title in listbox.SelectedItems.Result,Description)

textInput: Concat(ADDescription.SelectedItems,Result&",")

while using this scenario, Its working when there is only one item in the combobox and if we select it the description is selected default and added to the textbox

But, when we select multiple items in the combobox, on description it shows both descriptions are selected but its only populating one description on top of the list.

Can you help me with were i'm messing with the formula.

Thanks in advance.

I was experiencing an issue where my combo box would search properly when the form is in mode=edit, but not when mode = new. 

Based on your post, I modified my DefaultSelectedItems statement to match your logic and it resolved my issue.

If(IsBlank(Parent.Default)=true;[];[Parent.Default])

Thank you for posting this!
