SYMPTOMS

Changing the ActiveRow of a grid does not update the values of the object in every column.

CAUSE

Only the object that receives the focus will have an updated value.

WORKAROUND

  1. Create a new property of the form named oldrow and assign an initial value of -1.
  2. Place the following code in the grid's AfterRowColChange event: 
       ******* Begin AfterRowColChange *********
   IF This.ActiveRow<>Thisform.oldrow
      Thisform.oldrow=This.ActiveRow
      FOR lnI=1 TO This.ColumnCount
         lcsource=This.Columns(lnI).ControlSource
         IF TYPE(lcsource)<>"G" AND TYPE(lcsource)<>"M"
            This.Columns(lnI).SetAll("VALUE",&lcsource)
         ENDIF
      ENDFOR
   ENDIF
   ******** End AfterRowColChange *************

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a new form.
  2. Add Vfp\Samples\Data\Employee.dbf to the DataEnvironment of the form.
  3. Create a grid by dragging the table from the DataEnvironment to the form.
  4. Run the form.
  5. Open the Debug window, and type the following on the left side of the Debug window: 
       _Screen.Forms(1).Grid1.Column1.Text1.Value
   _Screen.Forms(1).Grid1.Column2.Text1.Value
   _Screen.Forms(1).Grid1.Column3.Text1.Value
   _Screen.Forms(1).Grid1.Column4.Text1.Value
  6. Select a cell inside the first column of the grid.
  7. Only Grid1.Column1.Text1.Value is updated in the debug window. None of the other values are updated.
