Step-by-Step Example
--------------------
1. Create a new form, and add a table to the data environment.
2. Drag the table from the data environment onto the form to create a new grid.
3. Place a command button on the form, and add the following code to its click
event:
ThisForm.Grid1.SetFocus
ThisForm.LockScreen = .T.
IF ThisForm.Grid1.RelativeRow = 1
=MESSAGEBOX("You cannot do this replacement from the top "+;
"of the Grid.",16,"")
*: If the active grid cell is in the top row of the grid, this
*: will display a message to the user.
ELSE
RepField = FIELD(ThisForm.Grid1.ActiveColumn)
ColumnNumber = "Column"+ALLTRIM(STR(ThisForm.Grid1.ActiveColumn))
ThisForm.GRID1.ACTIVATECELL(ThisForm.GRID1.RELATIVEROW-1,;
ThisForm.GRID1.RELATIVECOLUMN)
RepValue = ThisForm.Grid1.&ColumnNumber..Text1.Value
ThisForm.GRID1.ACTIVATECELL(ThisForm.GRID1.RELATIVEROW+1,;
ThisForm.GRID1.RELATIVECOLUMN)
yesno = MESSAGEBOX("Are you certain that you wish to replace "+;
CHR(13)+"Field "+UPPER(repField)+" current value?",36,"")
IF yesno = 6
REPLACE &RepField WITH RepValue
ThisForm.REFRESH
ELSE
WAIT WINDOW "Replacement Canceled" NOWAIT
ENDIF
ENDIF
ThisForm.LockScreen = .F.
4. Close, Save, and use the DO command to run the form. Place the insertion
point in any cell of the grid, and click the command button. If the pointer
has been placed in a cell that is in the top row of the grid, you should
observe the "You cannot do this replacement from the top of the grid"
message. Otherwise, you should see the "Are you certain..." message. If you
click Yes, the replacement should occur. If you click No, a wait window
indicating "Replacement Canceled" should appear.
