Unable to update the choices in a combo box

(0) ShareShare
ReportReport
Posted on by 332

My app contains a combo box (ComboBox1) that allows multiple selections.

 

The Update property of the combo box's data cards is:

Concat(ComboBox1.SelectedItems, Title&";"&Char(13))

 

The defaultselecteditems property of my combo box is:

RenameColumns(Filter(Split(Parent.Default, ";"), !IsBlank(Result)), "Result", "Value")

 

I have a submit button that submits the form and updates a Sharepoint list. All of that works fine. However, if I navigate to my form from a gallery item, make additional selections in the combo box, then submit the form a second time, only the new selections I've made are reflected in my Sharepoint list.

 

For example, if there are 3 default selected items in my combo box, and I choose 2 more selections, when I submit the form this is what shows up in my Sharepoint list:

 

;

;

;

Selection 4;

Selection 5;

 

This happens even though the combo box still shows that there are 5 items selected!

 

Any suggestions on how to fix this would be greatly appreciated. Thank you!

    Hi @T_A_M ,

    I have a blog on this process - unfortunately what you are doing is a workaround for something the control was never really designed to do. If you want to add new items, you need to delete what is there are re-select all that you need.

     

    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.
