Paul,

Ok, column makes sense *g*

Put code like this in the grid.MouseDown:

LPARAMETERS nButton, nShift, nXCoord, nYCoord

this.height, sysmetric(8))

if ( ( nXCoord < this.Partition ) and ;
     ( nYCoord > ( this.Top + this.Height - sysmetric(8) ) ) )
   nodefault
endif

This prevents the grid from "seeing" the mouse down in the left partition horizontal scrollbar.

>Sorry, I must have mis-stated my problem. The *row* is fine. The problem is that I want to lock a *column* in the left partition, so that they cannot accidentally scroll that partition so that is doesn't show my key field.
