Hi, I currently have a a!gridField() that is being used to add a list of samples. We have made the grid list selectable so that all rows can be selected, however there is a current request to have all rows in the grid selected without having to page to the next set of samples in the list when selecting the checkbox to select all rows. I wanted to see if this is even possible to configure in Appian?

You can add a button on the UI which just adds all the identifiers to the selection value.
Can you give an example of how that would be implemented?
Based on the example here: https://docs.appian.com/suite/help/23.1/recipe-limit-rows-to-one.html
You add a button that stores all employee IDs into local!selection.
Is there a way to have all grid checkboxes pre-selected without having to add a button?

Whatever local variable you have as the target of SelectionSaveInto, you would simply configure it in the first place to contain all identifiers found in the entire grid's data set (i wouldn't recommend this if your data set would be even a little bit large for starters, but if it's only medium or small, it's pretty simple - would require a separate pre-query).
This is what I currently have in my selectionSaveInto parameter: selectionSaveInto: { ri!selectedIndex, a!save(ri!saves, append(ri!saves, fv!selectedRows)), a!save(ri!saves,difference(ri!saves, cast(typeof(ri!saves),fv!deselectedRows))), }
It isn't a local variable since it's being called by a parent interface. And I also have a rule input for a List of Save using ri!saves.
Based on the documentation here, it seems like I would need to create the preselection of the rows using the selectedValue parameter.
What are you doing with "ri!saves"? You seem to be doing potentially-unnecessary redundant saving here - unless you require holding a copy of all data from all selected rows in ri!saves, which is what this is doing, it's almost never necessary. All you really need to do is save the identifiers for the selected rows, which is the value currently being saved into ri!selectedIndex in your pasted code - and also the value you'd need to be setting selectionValue to.

Then you'd need to pre-set it there, presumably in whatever local variable you have it set to (and if it isn't currently a local variable, i'd recommend changing to use one there for this purpose).
