Text Input "blank" until control has focus

[tjestesjr]

I have a strange situation and would like some input. I have a simple gallery with a Save button. The Save button is disabled until the top 2 text input controls are not blank.

If(
    IsBlank(txtDistCode.Text) || IsBlank(txtDistName.Text),
    DisplayMode.Disabled,
    DisplayMode.Edit
)

I have default data in the text boxes ThisItem.DistributorCode and ThisItem.DistributorName respectively. When I play my application the default state of my button is disabled (see screen below) even though there is default data.

 As soon as I set the focus to one of the input fields the text boxes suddenly aren't blank and my button works and my debug labels are populated. 

Is this the expected behavior? It there a way to work around this by setting the focus to a field on screen visible?

Hi @tjestesjr ,

Try the other way around

If(
   Len(txtDistCode.Text) > 0 && Len(txtDistName.Text) > 0,
   DisplayMode.Edit
   DisplayMode.Disabled,
)

I have tried the logic provided, but I get the same behavior, the button is disabled by default even though there are values in the text boxes. As soon as I select a text box, the controls are populated with values and evaluate correctly. It appears to be a matter of when the controls load on screen.

Hi @tjestesjr ,

What are these controls inside (if anything).

[tjestesjr]

These controls sit inside of a gallery.

@tjestesjr ,

I meant was this in a Component - I am assuming not. I also assume the button is inside the gallery ?

[tjestesjr]

Not a Component, button is outside of the gallery.

@tjestesjr ,

OK I have my mind around it now and it makes sense - if you are referring to an object inside a galley, there are many instances of it (one for each record in the gallery), so a control outside does not know which one to refer to until you select it in the gallery. You could try

If(
   Len(GalleryName.Selected.txtDistCode.Text) > 0 && Len(GalleryName.Selected.txtDistName.Text) > 0,
   DisplayMode.Edit
   DisplayMode.Disabled,
)

@WarrenBelz the logic that you provided is sound and I understand and agree with checking at the gallery level, that appears to make the most sense, but I am still facing the same behavior with the button being disabled until a control within the gallery is selected. Fortunately for me my UX person is good with this behavior saying that we shouldn't be saving unless changes are made. So, I am going to shelve this issue for now, although I am sorry that I wasn't able to find a solution for the next person.
