Saving DBGrid Column Width

[Richard Tully]

I am trying to save the column widths of a grid to the registry so that the
user will have the same column widths when they next open the form.
I seem to be able to get access to CustomDBGrid.Columns[i].Width
or CustomDBGrid.DataSource.DataSet.Fields[i].DisplayWidth
from within the form, but when using a component to do this the properties
are no longer visible
(DBGrid1 as TCustomDBGrid).Columns[i].Width)
Does anyone have any suggestions ?

I'd add a field to your component, something like

protected
FGrid: TDBGrid;

and set the grid:
published
Grid: TDBGrid read FGrid write FGrid;

Then, before saving the grid column widths, assign the
grid to the component:

MyComponent.Grid := DBGrid1;
with MyComponent.Grid do
begin
// Save the columns here
end;

HTH,

Ken

Well, yes. Do not cast to TCustomDBGrid, cast to TDBGrid, if you need to cast
at all. The TCustom classes you find in the VCL do not publish any properties
and have many things as protected that is than published by descendents.
