Grid Summary Row Data Source

I have successfully tied a grid to data source backed by an Oracle table. I would now like to add grid summary line that captures the total rows associated with the last fetch operation.

I cloned the current data source definition file and gave it a new unique ID. I added the following operation binding to the bottom of it to capture the count.

<operationBinding operationType="fetch">
  <selectClause>select COUNT(ID)</selectClause>
</operationBinding>

On the client side, I have the following new logic:

mGrid.setShowGridSummary(true);
mGrid.setSummaryRowDataSource(sortSummaryDS);
ListGridSummaryField totalField = new ListGridSummaryField("COUNT(ID)", "Total");
totalField.setAlign(Alignment.RIGHT);
totalField.setShowGridSummary(true);

Finally, I make sure the totalField is added to the grid field list. The summary is not being loaded properly, so I appear to be doing something wrong.

Questions:

1 - Did I construct the DS operationBinding properly?
2 - I used the field name of "COUNT(ID)" for the ListGridSummaryField - is that correct?
3 - Does the summary row data source automatically fetch when the grid does or do I need to explicitly do that?

Thanks.

No need for any of that, the total number of rows is available via calling ListGrid.getTotalRows() as soon as the DataArrived event fires.

Much easier to implement and it works perfectly.

Thank you.
