Remarks

This event is triggered under several circumstances:

· When the grid is first displayed.

· When the user scrolls through the grid with the horizontal scroll bar or navigation keys.

· When the LeftCol property is changed in code to a different value.

· When the C1DisplayColumn.Visible property of the current left column is set to False.

· When the C1DisplayColumn.Width property of the current left column is set to 0.

· When the user resizes the current left column so that it is no longer visible.

· When the user moves the current left column or moves another column into its place.

When multiple cell change events are sent, the order will be C1TrueDBGrid.SplitChange, FirstRowChange, LeftColChange, and C1TrueDBGrid.RowColChange.
