Hi Jack,

I have a similar problem when re-defining a grid from a method of the form. The code (part only) for the grid redefinition is...

	.Column1.FONTSIZE = 8
	.Column1.CONTROLSOURCE = "vInventory.itemno"
	.Column1.DynamicBackColor = IIF(parent_itm = 'Y',13565902,16777215)
	.Column1.WIDTH = 125

...the dynamicbackcolor value works OK only for the original grid definition.

If you get an answer I would appreciate a post here.

Regards
Doug Johnston
