Accounting for null value in Items property

(0) ShareShare

Posted on by glower power 161

Hello,

 

Use Case: I have a gallery where a user can select a specific item and certain properties from the item appear in a nearby form for editing. One of the properties can be edited from a list of choices in a dropdown in the form. I am able to successfully source the dropdown with the proper items as well as make the Default Item map to the selected Gallery item's field value, but the field is not required. When I change to a different selected value that does not have the field filled out, I want the dropdown choice to not choose anything for default. The problem is the dropdown is sourced from a specific DB view, and "no entry" is not a selection.

    I tried something like the below but the value is defaulting to the first value in the list of available choices instead of showing up blank. Maybe I need to use Concatenate to create a new column for referencing? 

     

    If(IsBlank(Gallery3.Selected.Title4_2), " ", Gallery3.Selected.Title4_2)

     

    The source is a specific DB table/field, hence I am not sure if I am going about it the right way..
