Change button backcolor in custom listview item

[Simon]

I have a listview with custom listitems that include a radButtonElement. How do I change the backcolor of the button? I've tried

    Me.MatchButtonElement.ButtonFillElement.BackColor = Color.LightGreen
    Me.MatchButtonElement.ButtonFillElement.BackColor2 = Color.LightGreen
    Me.MatchButtonElement.ButtonFillElement.BackColor3 = Color.FromArgb(122, 223, 136)
    Me.MatchButtonElement.ButtonFillElement.BackColor4 = Color.FromArgb(142, 237, 143)

and various other approaches but nothing has worked so far.

Hello Simon,

Thank you for writing.  

Here is a sample code snippet demonstrating how to change the button element's color in a custom SimpleListViewVisualItem: 

Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Me.CustomersTableAdapter.Fill(Me.NwindDataSet.Customers)

    AddHandler Me.RadListView1.VisualItemCreating, AddressOf radListView1_VisualItemCreating
    Me.RadListView1.DataSource = Me.CustomersBindingSource
    Me.RadListView1.DisplayMember = "ContactName"
End Sub

Private Sub radListView1_VisualItemCreating(ByVal sender As Object, ByVal e As ListViewVisualItemCreatingEventArgs)
    If Me.RadListView1.ViewType = ListViewType.ListView Then
        e.VisualItem = New MyCustomVisualItem()
    End If
End Sub

Public Class MyCustomVisualItem
Inherits SimpleListViewVisualItem
    Private buttonElement1 As RadButtonElement
    Protected Overrides Sub CreateChildElements()
        MyBase.CreateChildElements()
        buttonElement1= New RadButtonElement()
        Me.Children.Add(Me.buttonElement1)
    End Sub
    Protected Overrides Sub SynchronizeProperties()
        MyBase.SynchronizeProperties()
        Me.buttonElement1.Text = Me.Text

        Me.buttonElement1.ButtonFillElement.BackColor = Color.LightGreen
        Me.buttonElement1.ButtonFillElement.BackColor2 = Color.LightGreen
        Me.buttonElement1.ButtonFillElement.BackColor3 = Color.FromArgb(122, 223, 136)
        Me.buttonElement1.ButtonFillElement.BackColor4 = Color.FromArgb(142, 237, 143)
    End Sub
    Protected Overrides ReadOnly Property ThemeEffectiveType() As Type
        Get
            Return GetType(SimpleListViewVisualItem)
        End Get
    End Property
End Class

The following help article is quite useful for creating custom items in the different views: http://docs.telerik.com/devtools/winforms/listview/custom-items

I hope this information helps. Should you have further questions I would be glad to help.
