DataGrid Button? - Select All.

[g-pearl]

I am creating a menu selection using datagrid that I would like to have a button that selects all choices.

Is that possible and how. I have looked at cmdlet help and cannot find how but I could have overlooked it.

Thanks

I have created an acceptable solution by adding a new button to the form and if that button is selected manually filling in the variable as if select all was selected.
