  Hi,

  I took a look at your sample and have no idea why it does not work - it is up to the Mescuis support to comment on this.

  But as a workaround: instead of setting the footer during “InitializeComponent”, you could set it after filling the grid like this:

    Private Sub AddRows()
  
      grd.Redraw = False
      grd.Rows.Count = 1
  
      For n As Integer = 1 To 2000
        grd.AddItem("")
        grd(n, 0) = n
      Next
      grd.Redraw = True
  
      Dim FooterDescription1 As C1.Win.C1FlexGrid.FooterDescription = New C1.Win.C1FlexGrid.FooterDescription()
      Dim AggregateDefinition1 As C1.Win.C1FlexGrid.AggregateDefinition = New C1.Win.C1FlexGrid.AggregateDefinition()
      AggregateDefinition1.Aggregate = C1.Win.C1FlexGrid.AggregateEnum.Sum
      AggregateDefinition1.Column = 0
      FooterDescription1.Aggregates.Add(AggregateDefinition1)
      Me.grd.Footers.Descriptions.Add(FooterDescription1)
      Me.grd.Footers.Fixed = True
    End Sub

  After this change, the footer worked for me.

  Hope this helps

  Wolfgang

  Hi Peter,

  Since a footer row is already set in the designer, setting the row count to 1 does not seem logical. We recommend either commenting out the line of code that sets the row count in the designer or updating it to 2 (to account for both header and footer rows) for proper functionality. Please refer to the following code snippet for guidance:

  Private Sub AddRows()
    grd.Redraw = False
        'grd.Rows.Count = 2
        For n As Integer = 1 To 2000
            grd.AddItem("")
            grd(n, 0) = n
        Next
        grd.Redraw = True
    End Sub

  We have attached the updated sample for reference. Please check Test Flexgrid_Upd.zip

  As workaround, you can also follow the approach suggested by Wolfgang.

  PS: Thanks, Wolfgang, for looking into this issue.

  Kind Regards,
  
  Aastha
