Hi Nando. I'm not very sure about your problem.
I'm working in a database application and I've got TableViews that show
perfectly more than 5.000 rows.
This is the code of the _Data event.
' EVENTS.
' ================================================
PUBLIC SUB Table_Data(Row AS Integer, Column AS Integer)
DIM objColumn AS DYGridColumn
objColumn = m_columns[Column]
SELECT CASE m_bytMode
CASE DYGridModesEnum.DYGridModeBound
m_rsData.MoveTo(Row)
m_table.Data.Text = m_rsData[objColumn.DataField]
CASE DYGridModesEnum.DYGridModeAddItem
m_table.Data.Text = Split(m_itemList[Row], m_strFieldSeparator)[Column]
END SELECT
' In Boolean Columns, An Icon is shown instead text values.
IF objColumn.DataType = DYDataTypes.DYBoolean THEN
IF CBool(CInt(m_table.Data.Text)) THEN
m_table.Data.Picture = UtilLib.IconOK()
ELSE
m_table.Data.Picture = UtilLib.IconCancel()
ENDIF
m_table.Data.Text = ""
ENDIF
END
It can be a bit confussing but it's very simple:
- FIRST SELECT: There are two working states: bounded to a database or AddItem
mode (an Array suplies the info to the TableView).
- Aditionally, For boolean values of the database, the TableView only
show icons
instead of -1 or 0.
That's all. Hope you find it useful.
Regards.
