    Hello all,

    I am trying to add tab pages with embedded spread controls on the fly with code like the following: 

    With Me.TabControl1
    ' Create new tab page with spread control on it.

    .TabPages.Add(New TabPage("MyText"))

    With .TabPages(index).Controls
    .Add(New FpSpread())

    ' Setup embedded spread control.

    With DirectCast(.Item(0), FpSpread)
    .Name = "FpSpread" & index.ToString
    .DataSource = table
    End With
    End With
    The problem is that the DataSource property is still Nothing after setting it.
    Thanks in advance for any ideas and/or suggestions!

    I know the fpSpread is being created correctly because the Name property changes based upon the above code. Sorry, I forgot to note that in the first posting.

    Hello all,

    For the benefit of others, I needed to add at least one SheetView to the FpSpread. Once I inserted the following line before I set the DataSource property, it worked perfectly. 

    .Sheets.Add(New FarPoint.Win.Spread.SheetView)
    .DataSource = table
