Populate Form based on Gallery.Selected

Posted on by jtillinghast

Hi, all-- I'm trying develop an app for one of our teachers where students can leave feedback for another student. I have a data table which displays the roster, and a form which contains three fields: Student Name, Rating and Comments. I'd like to have the Student Name field populate automatically when the user selects a name off the roster. In other words, when you click "Student #1," that is automatically entered into the Student Name field.

The name of the data table is DisplayRoster. The control is RosterNames. In the Student Name data card, I have set Default=RosterNames.Selected. I get an error reading "The Property expects text values, but this rule produces incompatible Record values."

Any help is greatly appreciated!

Hi @jtillinghast

You get the error because RosterNames.Selected is a whole record containing all information about a particular student and not just the name.

To make it work you have to set the Default to:

RosterNames.Selected.DisplayName
In your case it might not be DisplayName it depends under what column name the student name is.

Thanks, Martynas-- I changed the Default to RosterNames.Selected.StudentName, where "StudentName" is the name of the appropriate column in the original table. Now I get an "invalid name" error over the box.

Wonderful! One clarification - I had to set it to DisplayRoster.Selected.StudentName, using the name of the table, not the name of the control. That fixed it, though. Thanks.
