I'm using sql query:

Select id, slapyvardis, lankomumas, zaidzia, sum(inesta), sum(atiduota), laikas, ivede, bonusai, (sum(inesta)* 0.02 + sum(atiduota)*0.01) as siulomi from esantys
where laikas > '2004.08.05' AND laikas < '2004.08.06' AND inesta >= 100 AND atiduota >= 0 group by id order by siulomi desc

and i can't edit any row in dbgrid...

because by this select the dataset is readonly

the readonyl is caused by
- aggregate functions
- order by clause (only bde relevant)

just tell me why you want to get it editable,
a workaround wold be to use a tstringgrid and fill there the dataset-content
or
to use cachedupdates with an updatesql-component as updateobject of your query
or
to use a memorydataset

siulomi is an aggregated field, so you can't edit it in any way.

Another alternative is show another modal dialog ( when double click or "modify" is pressed ) where to put the values ( without DBControls ) and modify them with a SQL Statment, and then refresh the dataset.

you can try to use, in the DBGrid, the Option "dgRowSelect" to select the entire row and, on the OnDblClick Event, show your edit form ( as modal ). If ModalResult is set to True ( you added/changed the record ), then try to refresh the dataset

curr_id := Dataset.FieldByName('id').value;
Dataset.DisableControls;
Dataset.close;
Dataset.Open;
Dataset.Locate('id', curr_id, [locaseinsensitive] );
Dataset.EnableControls;
