Weird Glitches in ForAll & Getting Galleries to load Properly for OnChange

Posted on by AnthonyIsAdulti

Hi everyone,

I have this weird problem where when I call If(IsBlank(LookUp) in my forAll (my forall is going through a collection seeing if the record exists already in a Dataverse table) it glitches out badly and doesn't perform as expected.

I also have this issue where I have a gallery that has controls with onChange functionality, that only glitch when a large datasource is loaded. I even have a timer when the screen becomes visible to give it time to load but it doesn't work no matter how much time I give it. Does anyone have a solution for that?

Hi,

You didn't show us any code, or explain what "glitches means".

Can you help me understand what you need help with, that you shared?

1. Share your code

2. Share your Ui so we can see

3. Share the OnChange

4. Share your Onvisible

etc etc

Please, share as we cannot see your screen and nothing you said is going to specifically help us help you :-( I am afraid, without seeing it.

Here is the code for the save button.

ForAll(requestedToolCollection,

If(!IsBlank(LookUp('Dataverse Table', 'Dataverse Table ID' = ThisRecord.'Dataverse Table ID' && 'Item #' = ThisRecord.'Item #' && 'Tool Status' = 'Dataverse Table Status Choices'.New)),

Patch('Dataverse Table', LookUp('Dataverse Table', 'Dataverse Table ID' = ThisRecord.'Dataverse Table ID' && 'Item #' = ThisRecord.'Item #' && 'Tool Status' = 'Dataverse Table Status Choices'.New),
{
Requested: ThisRecord.Requested,
Comments: ThisRecord.Comments
}
)

,

Patch('Dataverse Table', Defaults('Dataverse Table'),
{
'Item #': ThisRecord.'Item #',
Name: ThisRecord.Name,
Requested: ThisRecord.Requested,
'Dataverse Table ID': Dataverse Table_ID,
'Tool Status': 'Dataverse Table Status Choices'.New,
'Tool / Toolkit': ThisRecord.Name,
Comments: ThisRecord.Comments
}
)

)

);

The collection "requestedToolCollection" works fine and has all the proper values, its just when I patch those values into the Dataverse table it patches incorrectly. It hasn't been consistent so far, or at least have a pattern that I have been able to notice.

he save button itself doesn't have any onChange code, but its onVisible is when there is a change of any of the controls in the gallery.

In my gallery, I have an onChange on the text input and combobox controls that patches that value to the "requestedToolCollection."

That is all. Let me know if you have any questions.
