Strange problem 3

In a grid (subclassed),

grid.recordsource="table1"
grid.columns[1].contorl="field1"

The grid becomes read-only.

After I changed it to:

grid.recordsource="table1"
grid.columns[1].contorl="table1.field1"

the grid can allow changes.

What could cause this?

I don'ät understand "grid.columns[1].contorl"
If one assigns an expression othere than "Table.field" to the ControlSource
properrty of a column , for example
grid.columns(1).ControlSource=Week(table.datefield))
it becomes readonly. This may be similar. Just 'field' is not specific
enough to work properly as a ControlSource

No. I didn't use an expression. it took me an hour poking around
.readonly and .enabled everywhere in the grid before I decided to try
qualifying the field names with an alias in the controlsource, and fixed
the problem. What the....

The lesson: ALWAYS qualify your fields in grid.columns[].controlsource.

"field" might be seen as an expression from VFP's POV when the
controlSources are set up.

Strictly speaking, even "table.field" is an expression. <g> The difference
is that it is a fully SCOPED expression.
