Hi Joe, try this:
1)

SELE ("TmpMatList")
WITH This.MyGrid1
	.GridLines    = 3
	.RecordSource = "TmpMatList"
ENDWITH

>I am having a problem getting a checkbox to work in a grid. I've got a cursor (TmpMatList) that is the result of a query that I created by saying, "...INTO CURSOR TmpMatList NOFILTER READWRITE" (VFP8), then I create the grid, like below...I SEE the checkbox just fine, but no matter what I do, I cannot click it! It looks like it's disabled, but I clearly enable it AND make sure it's not read only. What am I missing???
