I want to create a vertical gallery that will be a form of sorts for filtering a data table. Each row will just be a label and a text input, as such:


I populate the gallery with this in the Items property:
Table({field: "BillingRegion:"}, {field: "CoreCount:"}, {field: "FeatureName:"})
When the user clicks on the Apply Filter button, I need to construct a concatenated string from all of the textboxes. I'll need to do a null check on each input to construct the string for the API call so I need to access each individual textbox. However, I can only access an individual row with the gallery.Selected property. I tried .AllItems but that doesn't seem to have any properties I can access after that.
Ideally, I figured I would be able to do something like:
Set(billingRegionFilterText, gal_StorageTest.txt_inpt.Text WHERE field = "BillingRegion");
Set(coreCountFilterText, gal_StorageTest.txt_inpt.Text WHERE field = "CoreCount");
I know that WHERE isn't a PowerApp feature but I'm just using it to illustrate the logic I'm trying to achieve.
