Example
The following code sample demonstrates how to use the column header properties of the UltraListViewDetailsSettings object (which is the data type of the UltraListView's ViewSettingsDetails property):

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinListView

    Private Sub ConfigureColumnHeaders()

        Dim detailsSettings As UltraListViewDetailsSettings = Me.ultraListView1.ViewSettingsDetails

        '	Set the ThemedElementAlpha property of the ColumnHeaderAppearance
        '	to 'Transparent' so that headers are not themed
        detailsSettings.ColumnHeaderAppearance.ThemedElementAlpha = Alpha.Transparent

        '	Set the borders for the column headers to 'RaisedSoft'
        detailsSettings.ColumnHeaderBorderStyle = UIElementBorderStyle.RaisedSoft

        '	Assign an ImageList to provide the images for the column headers
        detailsSettings.ColumnHeaderImageList = Me.columnHeaderImageList

        '	St the size for the column header images to (16 X 16)
        detailsSettings.ColumnHeaderImageSize = New Size(16, 16)

        '	Use the 'Standard' HeaderStyle
        detailsSettings.ColumnHeaderStyle = HeaderStyle.Standard

        '	Don't show the sort indicators
        detailsSettings.ColumnsShowSortIndicators = False

    End Sub

    Private Sub ultraListView1_ColumnSorted(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinListView.ColumnSortedEventArgs) Handles ultraListView1.ColumnSorted

        Dim listView As UltraListView = CType(sender, UltraListView)

        '   Assign an image to represent the sorted state
        If e.Column.Sorting = Sorting.Ascending Then
            e.Column.HeaderAppearance.Image = 0
        ElseIf e.Column.Sorting = Sorting.Descending Then
            e.Column.HeaderAppearance.Image = 1
        End If


        '   Clear the image from the other columns
        If Not e.Column Is listView.MainColumn Then listView.MainColumn.HeaderAppearance.Image = Nothing

        Dim column As UltraListViewSubItemColumn = Nothing
        For Each column In listView.SubItemColumns
            If Not column Is e.Column Then column.HeaderAppearance.Image = Nothing
        Next

    End Sub

		}
