>In one of my old VFP6 application, which uses GHL, I noticed the following: if I remove textbox from the grid's column for logical field in run-time, put checkbox instead and set sparse property for this column to .f. (GHL is added in design-time), all records in that column become highlighted. I am wondering, if you can reproduce this effect, and where is a problem.

Hi Nadya,

Did you try to call ghl.Init() after this manipulation?
