When I first started developing my review/edit screen I added a gallery and set the edit form items to gallery.selected. While that usually works I had some issues with certain controls not being populated. I have switched the selected gallery item to push the record to a variable instead(glbFormData). My question is how to populate the controls? By default they use Parent.Default but this doesn't always work. Should I be referencing the glbFormData variable instead? Like this:

Text field example - glbFormData.'Campaign Notes'

Combo box example - {dk_tacticname:glbFormData.Tactic}

Is this best? Is there a better way? Anything I should look out for?

@futr_vision whether you use a Variable or Gallery.Selected, the results will be the same because both options will return a record. I assume you're not having problems with the Text input control but you're experiencing issues with the ComboBox control.

Assuming you're using Parent.Default on the DefaultSelectedItems property, then this is correct. If you're having issues, I would suggest checking the Items property of that ComboBox and ensure the Default property of the DataCard container is something like "ThisItem.'Your Field Name'".

The method I chose was to push the gallery item record to a global variable and then reference the column as I outline. Seems to work great but it does fail in one specific instance. I have a combo box control that becomes visible if a radio button's value is yes. If it is yes then there should be a value to populate that combo box but for some reason it doesn't, and I do not receive any errors. Here is the code I am using for the DefaultSelectedItems.

If( Self.DisplayMode=DisplayMode.Edit && Text(RB_PartneringReview.Selected.Value) = "Yes", If( IsBlank(newPartner), {CB_PartnerNameReview: glbFormData.'Partner Name'}, newPartner ), Blank() )

If I click on the glbFormData.'Partner Name' it show me the value 'Test Partner 4'. Just to make sure I added a label to the app and set the text to glbFormData.'Partner Name'. Sane results. I'm just not sure why the combo box is blank unless I am blanking it out some other way?

@futr_vision sorry I did not receive a notification that you had responded.

What is "newPartner" ? Another variable?
