Hello

Until now, I used "Columns[0].DrawingOptions := doCustomOnly;" and the corresponding routine to make a whole column look fixed (ie. grey), but I was wondering if I could simplify the code by using the following code:

CODE

FixedCols := 1;
Columns[0].ColumnStyle := ???

Besides the appearance, since this column is 100% read-only, the column should be unselectable ,ie. the user shouldn't be able to navigate to this column through either the keyboard arrow keys or mouse clicks. Is it possible to forbid this through code?

Thank you.

Hello Fred,

Maybe Enabled property of Column can help?

Best regards

You can use the column's color property to set the fixed column colour.

CODE

FixedCols := 1;
Columns[0].Enabled := False;
Columns[0].Color := clSilver;

Thanks guys for the tip.

CODE

Columns.Add(TNxTextColumn,'Key');
Columns[0].Name := 'key';
Columns[0].Enabled := False;
//clSilver, clGray, clLtGray, clBackground
Columns[0].Color := clBtnFace;

Columns.Add(TNxTextColumn,'Value');
Columns[1].Name := 'value';

FixedCols := 1;

BTW, what is the purpose of FixedCols, really? When I change the above to "2", it makes no graphical difference, the "Value" column is still displayed as before and I can navigate up/down using the arrow keys.

FixedCols is only relavant if the number of columns in the grid exceeds the visible width of the grid (i.e. if the horizontal scrollbar is visible). When scrolling to the right to see the columns that don't fit, the FixedCols on the left of the grid will NOT scroll and will always be visible.

I see. Thanks.
