I'm using a memberclass in the grid def, so my custom col is loaded 
anyway...also with a custom header...
getting a custom text (or whatever) is tricky.

yup...  if you add a subclass of column it does.

so if you addobj()... the classs automatically adds it to the column collectoin

you can use addcolumn.
i choose to use addobject because i have a column class with when and valid 
events and keypress events, etc.
many ways to do this with the fox...

Got it, thanks. Somehow or other I didn't set the .RecordSource because I was 
afraid that the fox would start
autoloading column objects. I'm using .AddColumn() rather than .AddObject().... 
Am I a missing something else?

Lew,
I don't touch the bindcontrols property, its set to the default.

the table or cursor needs to be opened before you programmatically assign the 
objects to the grid.
i use this at the start of my class to setup the grid
grid1.RecordSource= alias1
grid1.ColumnCount=0    && insure that no columns
*i can also assign others if i want, or set the colors in the grid object.

i use a class:  grid1.AddObject(ccol,'GRID_COL')  to add a column to the grid, 
where ccol is the name of the
column
*heres an abstract of code that i use to build each column
    With grid1.&ccol
            .header1.Caption= Alltrim(GridS.Heading)
            .Width = GridS.Width

            If .edit_mode=0 And GridS.col_type<>'check'    &&cant do this for 
check boxes
                *for readonly fields except checkboxes
                    .ControlSource = "' '+ALLTRIM("+Alltrim(GridS.cs)+")"
                   *assigned the quote above as is -- is required for my 
concept to work. this also makes it
readonly
            Else
                .ControlSource = Alltrim(GridS.cs)
            Endif
    endwith

hopefully that will get you started.

Hi Jay:
 
Started playing with table driven grids. Things went ok until I started with 
multiple use's for the same
table, set filters, etc... until I discovered setting bindcontrols to .f. while 
loading the col definitions.
When the entire form is good to go, setting bindcontrols .t. seems to work.  
Any idea what up with this?
