How to get Current row number of a DBGrid within a filtered Query?
«
on:
June 01, 2017, 01:56:56 pm »
I have found other solutions to obtaining the current selected row number of a DBGrid. But those seem to return the Record Number of the dataset.
If a Query is filtered, how do I obtain the current selected row number of the DBGrid?
Hope this makes sense.

you ask the dataset eg
Code:
[Select]
showmessage(inttostr(DBGrid1.DataSource.DataSet.RecNo));
oops to hasty didn't read the question through. sorry but this one I'll have to answer it after work.

@JSN
Ideally you should write a class helper or modify DBGrids.pas and publish a new property. Anyway I found a way, all you have to do is replace "Name" with the field you wish to see(I assume multiselect is off, and your form name is Form1):
Code: Pascal
[Select]
[+]
[-]
procedure
TfMain
.
DBGridDrawColumnCell
(
Sender
:
TObject
;
const
Rect
:
TRect
;
DataCol
:
Integer
;
Column
:
TColumn
;
State
:
TGridDrawState
)
;
var
Row
:
Integer
;
begin
if
gdSelected
in
State
then
begin
Row
:
=
Trunc
(
Rect
.
Bottom
/
(
Sender as TDBGrid
)
.
DefaultRowHeight
)
-
1
;
Form1
.
Caption
:
=
DBGrid
.
DataSource
.
DataSet
.
FieldByName
(
'NAME'
)
.
AsString
+
' '
+
IntToStr
(
Row
)
;
end
;
end
;
