Table Builder...

[Gary L. Olivieri]

I am trying to create a set of functions so that I can dynamically and
programmaticall y create a table.

The table will be a calendar when it is displayed on the screen and has 5
types of cells.. Month header, Date, Info, Contents, and Filler.

This is the code that I am using:

Private Sub Page_Load(...

Build Calendar()

End Sub

Private Sub BuildCalender()

Table1.Rows.Add (BuildRow(1,Tod ay())

End Sub

Function BuildRow(byval type as integer, byval sDate as Date) as TableRow
BuildRow.Cells. Add(BuildCell(1 ,1))
End Function

Function BuildCell(byval type as integer, byval contents as integer) as
TableCell

Select Case Type
Case 1 ' Month
BuildCell.Borde rStyle = BorderStyle.Rid ge
BuildCell.BackC olor = BuildCell.Borde rColor
BuildCell.Text = "Test Month Text"
BuildCell.Heigh t.Pixel(24)
BuildCell.RowSp an = 14
End Select
End Function


When I try to run this I get an error "Object reference not set to an
instance of an object." on line 41 which is
BuildRow.Cells. Add(BuildCell(1 ,1))

Any help with this would be great!

Thanks in advance,

Within the BuildRow Function, you get a "free" variable, with the
same name as the function to use as its return value. But, in this case,
that return value is still an Object and you have to instantiate it before
you can call methods on it, something like

Function BuildRow( _
byval type as integer _
, byval sDate as Date _
) as TableRow
' Not sure what you do with "type" (dodgy name) and sDate, but

BuildRow = New TableRow()

BuildRow.Cells. Add(BuildCell(1 ,1))

Return BuildRow
End Function
