I currently have a filler form with query and submit features to a SQL Server database (directly. not with a web service). I'm noticing when I'm dragging my SQL tables onto my form, regardless of how the table is set up, the control is a text box. I've gotten into the habit of changing them, but a lot of my original form design uses multiple selection.
We have a table in SQL set up with all the values, and unique IDs, but the form will not let me use the multiple selection control. Here is what I've tried so far.
1) I've tried manually changing the field control to the multiple selection control. It states the field has to be repeating.
2) I've tried going into the properties of the field, but everything is grayed out and I cannot change the field to repeating
3) I've tried manually creating my own multiple selection control, having it query the selections from the database then trying to bind it or move it into the field it needs to be. I either get told that the group cannot accept changes, or that I have to change the field to repeating, which it does not let me do.
I've seen forms in the past with multiple selection list boxes but I haven't found a SQL specific tutorial to do so. ANY help or points in the right direction would be amazing.
