Hi, Is there any way to determine when a column gets added or removed from the report control from the field chooser. I know _ColumnOrderChanged captures this, however I only want to know if something gets added not if other things happen such as column location changes or group by box changes which are also covered in this event.

Hi,
There is no special event for add/remove columns.
But you may store names of visible columns in some collection and check is this changed in ColumnOrderChanged.
As I see this easy to implement.
Also you may use Column.Tag property to identify column. ------------- Regards, Andrei Melnik |

Thanks for the advice, I already use the tag for something else, but a collection would work just fine. If its possible to have it be an enhancement to the control that would be great for future.

Andrei,
Add the event and a few thousand users won't have to add code to do it themselves
 . As I said in my post: Managing columns, also support members are welcome with ideas and maybe you have already implemented some. You're welcome to add them or share with us, Andrei  Thanks in advance ------------- Product: Xtreme SuitePro (ActiveX) version 15.0.2 Platform: Windows XP (32bit) - SP 2 Language: Visual Basic 6.0 Zero replies is not an option.... |

Hi Andrei, The Tag property is useful, but very limited. I use the ComponentOne VSFlexGrid control a lot, and it has some very useful properties: RowData, ColData and CellData. The great thing about these properties is that they accept Variants instead of just strings, so you can create a class with a bunch of your own properties that you want to track for Rows, Columns and individual Cells, and then attach the class to the appropriate property. Similar properties in the ReportControl would be very useful and much more powerful that using Tag. ------------- Product: Xtreme SuitePro (ActiveX) version 16.2.6 Platform: Windows XP - SP3 Language: Visual Basic 6.0 SP6 |

Our Tag property is Variant too :).
Folowing objects have Tag property:
- ReportColumn
- ReportRecord
- ReportRecordItem
EXAMPLE:
'' Store
Set Column.Tag = New Collection
Column.Tag.Add "Column.Tag = Collection" '' Using
wndReportControl.Columns(3).Tag.Item(1)

That's good to know Andrei! I just saw a Tag property, and figured it was the same as the standard VB Tag property. I'll revisit the documentation along with Aaron ;) ------------- Product: Xtreme SuitePro (ActiveX) version 16.2.6 Platform: Windows XP - SP3 Language: Visual Basic 6.0 SP6 |
