PRB: Values Are Not Updated in Each Column When Changing Rows

• Microsoft Visual FoxPro for Windows, versions 3.0 and 3.0b

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.
