Walter,

to change the backcolor of a header of a column, you first need to set the EnableHeadersVisualStyles property of the DGV to false.

You can try the code below:

Public Class Form1
    Private tList As New TestList
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim bdStyle As New DataGridViewCellStyle
        bdStyle.BackColor = Color.Red
        DataGridView1.Columns(0).HeaderCell.Style = bdStyle
    End Sub
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        DataGridView1.EnableHeadersVisualStyles = False
        tList.Add(New Test)
        DataGridView1.DataSource = tList
    End Sub
End Class
Public Class Test
    Private _test As String
    Public Property Caption() As String
        Get
            Return "test"
        End Get
        Set(ByVal value As String)
            _test = value
        End Set
    End Property
End Class
Public Class TestList
    Inherits List(Of Test)
End Class

Just create a new WinFor Project, add a Button and a DatagridView and paste this code inside the code editor.

If you have got questions about this, just ask.

In a perfect world,
users would never enter data in the wrong form,
files they choose to open would always exist
and code would never have bugs.

Answer 3

Thank you for your tip, Nico, but somehow it did not do it for me.

If I interpret your tip correctly, it would probably color the entire title header red, which is not what I want. I want to color the header of each column separately.

I just tried some of the commands of Hannes Heslacher's reply and they did what I wanted.

Thanks again - Walter

Thank you, Hannes, for your help: that did it for me!

Very important was the following, which I set in the DGV property.

DataGridView1.EnableHeadersVisualStyles = False

The next steps were:

        Dim bdStyle As New DataGridViewCellStyle
        bdStyle.BackColor = Color.Red
        DataGridView1.Columns(0).HeaderCell.Style = bdStyle

which will address each column header by changing its index.

Great, thanks again

Best regards - Walter
