[SOLVED]DBGrid, the cursor won't move to the persistent field.
«

Hi every body!
I have a dbgrid with 5 fields+a persistent field.
Autoadvance is at aaRightDown.
I use RETURN to move between the columns .
But when the cursor is on the fifth column, it would not move to the persistent one.
is it a bug?

Isn't a persistent field a Read only? if so then what good would be the cursor there ?

Hi there
Of course the persistent field is a read only, but the cursor must cross it, in order to get
the next row.
for this I used the next code:
Code: Pascal
[Select]
[+]
[-]
procedure
TF_MAINFORM
.
DBGrid2KeyDown
(
Sender
:
TObject
;
var
Key
:
Word
;
Shift
:
TShiftState
)
;
begin
if
key
=
VK_RETURN
then
if
DBGrid2
.
SelectedColumn
.
Index
=
4
then
DBGrid2
.
SelectedIndex
:
=
5
;
end
;

maybe you should be cycling the columns each time you move up or down and always check for the field type and if not desirable then go to the next one until you fine one that is ..
if you come to the end before you find one then you just don't move …

Hi every one !
@jamie
In fact the only fields I can input the data are 1,2 and 3.
the code became:
Code: Pascal
[Select]
[+]
[-]
procedure
TF_MAINFORM
.
DBGrid2KeyDown
(
Sender
:
TObject
;
var
Key
:
Word
;
Shift
:
TShiftState
)
;
begin
if
key
=
VK_RETURN
then
if
DBGrid2
.
SelectedColumn
.
Index
<
3
then
DBGrid2
.
SelectedIndex
:
=
DBGrid2
.
SelectedIndex
+
1
else
begin
DBGrid2
.
SelectedIndex
:
=
1
;
if
not
MDT
.
T_NOTE
.
EOF
then
MDT
.
T_NOTE
.
Next
end
;
end
;
