Change appearance alternated columns in ultragrid
posted

Hi, i have this prob,

i want change the appearance at alternated columns in an ultragrid.

1 prob, i need to understand if the column in visible or not

2 prob i need to understand the visible order in the ultragrid

there is a columns collector of visibles columns (in the visible order)?

i start with:

For Each colonna In UltraGrid1.DisplayLayout.Bands(0).Columns
    If Not colonna.Hidden Then
        If scurisci Then
            colonna.CellAppearance.BackColor = Color.FromArgb(80, 80, 80)
            colonna.CellAppearance.ForeColor = Color.FromArgb(255, 255, 255)
        Else
            colonna.CellAppearance.BackColor = Color.FromArgb(255, 255, 255)
            colonna.CellAppearance.ForeColor = Color.FromArgb(80, 80, 80)
        End If
        scurisci = Not scurisci
    End If
Next

but where i have a different visible sort not work, well i can retrive the visible order but i try to find the best solution.

tks

    Hello,

    You can get the first visible column using the UltraGridBand.GetFirstVisibleCol(), and then each subsequent column using the UltraGridColumn.GetRelatedVisibleColumn() method. I was able to achieve a similar effect using the following code:


    Private Sub UltraGrid1_InitializeLayout(sender As Object, e As Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs)
        Dim layout = e.Layout
        Dim band = layout.Bands(0)
        Dim scrollRegion = layout.ColScrollRegions(0)

        Dim column = band.GetFirstVisibleCol(scrollRegion, True)
        Dim alternate As Boolean = False

        While column IsNot Nothing
            If alternate Then
                column.CellAppearance.BackColor = Color.Red
            End If
            column = column.GetRelatedVisibleColumn(Infragistics.Win.UltraWinGrid.VisibleRelation.[Next])
            alternate = Not alternate
        End While
    End Sub

    Please let me know if I can further assist you.
