Is there any simple way to affect columns in a DataGridView by using the ReadWriteAuthorization component the same way you would with simple controls? If not, what's the preferred way to call the CanReadProperty/CanWriteProperty methods to hard code this? It seems that these cannot be exposed as shared methods like CanEditObject.

Thanks in advance.

I am sure that it could be extended to include the DataGridView, but in the meantime, you may want to check to see if you can make cells editable or read-only as CanReadProperty/CanWriteProperty could change from row to row.

That's a good point. Probably the best way to handle this would be on an event that fires as each row is processed by the grid. Infragistics grid for example has RowInitialize.

I have a co-worker who used a delegate against the DataGridView.BackColor property, "pointing" it to a function that would return an integer value (corresponding to a color) if a particular criteria was met or not. If I'm not mistaken, this falls under .NET's complex binding feature.

I don't see why this approach wouldn't work using the DataGridView.ReadOnly property.
