TCRDBGrid summary problem

Hi,

I have 2 CRDBGrids, one master, second details.
In the details grid I have a summary tab which shows a sum of one column.

The problem is, the sum doesn't change when I select the different record in the master grid. It always shows the sum of the first record in the grid.
I'm using ADO queries reading data from access database for these grids.

How would I fix this problem?

Thanks,
Dragan

Calculated Fields are only for display purposes only,
They are not Real (Persistent) Fields they only exist in Memory.
You CANNOT Search or Sort on Calculated Fields.
So, be aware that Calc. Fields are not real.

To use a Calculated Field, you have to do 2 things
        -Create a New field for a Table using the Fields Editor
                (Right Click on Table and select Fields Editor
        -Use the Table's OnCalcFields Event, to do the calculation and put the data in the Calc. Field
                e.g.
        n1:=T1.FieldByName('N1').AsInteger;         // N1 and N2 are Real Fields
        n2:=T1.FieldByName('N2').AsInteger;
        T1.FieldByName('CalcN3').AsInteger:=n1+n2; // CalcN3 is a Calculated Field (not real)

ARe you using a Calculated Field to show the Sum?

No, I'm not using calculated field.

I'm using CRDBGrid which has an option to show a sum of the column in the summary tab (dgeSummary).
The way you set it up is: set OptionEx property to ([dgeEnableSort,dgeLocalFilter,dgeSummary]).
Then edit the columns of the grid, and select the column and change the SummaryMode to smSum.

It works fine for the first record when I run the App, but when I select a different record, the sum still shows the sum for the first record in the master grid.
