Filemaker record reorder popup

Hi,

I have a list of projects in a single table each of which has a UID serial number field and separate numerical sort order field.

Wondering if there is a way to display the list in a layout or portal and allow user to select any item in the list,  and move it up or down the list order,  updating the 'sort order'  field with its new position.  

The purpose is to be able to create custom sort order for report layout.

Any pointers much appreciated..

I'm sure there are a number of ways this could be done so I'll just suggest one that I used here recently. In the portal row, I have two arrow buttons, one pointing up and one pointing down. Each button is attached to the same script called simply "Move Row Up/Down". The "Up" arrow button has "Up" as a script parameter, the "Down" arrow button has "Down" as the parameter.

The script looks like this:

If [ Get(ScriptParameter) = "Up" ]
#
#Already First Row
   If [ Get ( ActivePortalRowNumber ) = 1 ]
      Beep
      Exit Script [ ]
   End If
   #
   #Move Up One
   Set Field[ SetItem::Order ; SetItem::Order - 1 ]
   Go to Portal Row [ Previous ]
   Set Field[ SetItem::Order ; SetItem::Order + 1 ]
   #
Else
   #
   #Already Last Row
   If [ Get ( ActivePortalRowNumber ) = Count( SetItem::zk_SetItem_ID )
      Beep
      Exit Script [ ]
   End If
   #
   #Move Down One
   Set Field[ SetItem::Order ; SetItem::Order + 1 ]
  Go to Portal Row [ Next ]
  Set Field[ SetItem::Order ; SetItem::Order - 1 ]
   #
End If

My actual script includes an additional option if the ALT/Option key is held down that moves the row to the top or bottom of the list. The one for moving to the top is:

If [ Get ( ActiveModifierKeys ) = 8 ]
   Set Field [ SetItem::Order ; 0 ]
   Commit Records/Requests [ Skip data entry validation ; No dialog]
   Refresh Window [ ]
   Perform Script [ "Renumber Set" ]
End If

The sub-script at the end resets the Order field back to the actual number of the Portal row.
