Hi,
I'm switching to VirtualMode for the ReportControl, and everything runs fine, but 1 problem I got:
With normal mode, I doubleclick on a row. In the Event 'RowDblClick' I got the value of a column, like:
Value = Row.Record.Item(8).Value
This doesn't seem to work in Virtual mode? (Value = empty)
How do I get the value of a column when double clicking on a row?
Additionally: Does the FilterText work with the VirtualMode?

| Problem is that with Virtual Mode you really only have 1 record that exists. Virtual mode is designed to be used with the data stored in some external data source like a database or some array. So in double click event you want to search for row and column that was clicked, then you can pull this data from your external data source. This is the same way you should be drawing the items in the BeforeDraw event, determine the row and column, then draw the appropriate caption. |

| No, filter text will not work for some of the same reasons I gave above. There is only 1 record object. But you can easily apply your own custom filter in BeforeDrawRow since you are manually drawing all rows anyway. |

That's a very good tip
 I almost abandoned the FilterText method ;-)

One more question:
I managed to add filter in the BeforeDrawRow Event, but despite that all items are always displayed.
How can I prevent displaying a row in the BeforeDrawRow event?

After giving this some more thought, about the only way to do this in virtual mode would be to externally create a subset of your data source and use this subset to place data in the report. |
