Cannot replace the whole Ribbon Application Menu button image
posted

Do you know what I did wrong why I can't replace the whole button image (white circle around)? See the attached snapshot. I have tried many different image sizes with same result.

    I tried 37x37 and 43x43 images of a circle, but had the same problems as dtjoa.

    I fixed the problem by using a custom draw filter class.  Set the UltratoolbarsManager.Ribbon.DrawFilter to an instance of this AppButtonFilter, and add the desired image for your logo in the Resources (or supply it some other way)

    <code lang="vb.net">

        Public Class AppButtonFilter
            Implements Infragistics.Win.IUIElementDrawFilter

            Public Function GetPhasesToFilter(ByRef drawParams As Infragistics.Win.UIElementDrawParams) _
            As Infragistics.Win.DrawPhase _
                Implements(Infragistics.Win.IUIElementDrawFilter.GetPhasesToFilter)
                If (TypeOf (drawParams.Element) Is ApplicationMenuButtonUIElement) Then
                    Return Infragistics.Win.DrawPhase.BeforeDrawImage
                Else
                    Return Infragistics.Win.DrawPhase.None
                End If
            End Function

            Public Function DrawElement(ByVal drawPhase As Infragistics.Win.DrawPhase, _
                                        ByRef drawParams As Infragistics.Win.UIElementDrawParams) As Boolean _
                                        Implements Infragistics.Win.IUIElementDrawFilter.DrawElement
                Dim elementRect As Rectangle = drawParams.Element.Rect
                elementRect.Inflate(-1, -1)
                drawParams.DrawImage(Resources.RedCircleImage, elementRect, True, Nothing)
            End Function
        End Class

    </code>

     

    Here are the results:
