how to use DrawColumnCell to just draw active cell in different color?
must be really simple!!
This code paints the whole active Column but active Cell only?
Code: Pascal
[Select]
[+]
[-]
if
DBGrid
.
SelectedField
.
Index
=
DataCol
begin
TDBGrid
(
Sender
)
.
Canvas
.
Brush
.
Color
:
=
clblue
;
TDBGrid
(
Sender
)
.
Canvas
.
Font
.
Style
:
=
Font
.
Style
+
[
fsBold
]
;
TDBGrid
(
Sender
)
.
Canvas
.
Font
.
Color
:
=
clRed
;
end
;

Don't use OnDrawColumnCell, you'd have to draw everything by yourself. Application of the OnPrepareCell event is much simpler: it is called immediately before the cell is painted, all canvas properties already have been set, but in this event you can override them; a set of parameters comes with the event to decide which cell is painted.
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
DBGrid1PrepareCanvas
(
sender
:
TObject
;
DataCol
:
Integer
;
Column
:
TColumn
;
AState
:
TGridDrawState
)
;
begin
if
(
[
gdSelected
,
gdFocused
]
*
AState <>
[
]
)
and
(
DBGrid1
.
SelectedColumn
=
Column
)
then
begin
DBGrid1
.
Canvas
.
Brush
.
Color
:
=
clRed
;
DBGrid1
.
Canvas
.
Font
.
Color
:
=
clWhite
;
end
;
end
;
