Mike, thanks for the advise.

I downloaded and installed version 2012.2.

Now the problem is that after I ran the Toolbox utility I still do not have 2012.2 in the toolbox. It exists for the CSharp templates, but I am working with a VB project, and it is not there.

From the dos-prompt window I see that the utility did not report anything about VB templates (see below).

Do I have to do anything extra to get 2012.2 objects in my VB projects Toolbox?

Hi Georgi,

your sample works well as a sample.

To make it useful for me, I had to translate it to vb, and make the width of the scroll bar variable.

First, the original sample falls apart when I try to change the scroll bar width from hardcoded 50 to 100.

Second, my vb version does not work properly :-( .

Could you please take a look at the vb project I attached.

Thanks,

Helen

Hi Helen,

I think Georgi's sample code is a little overcomplicated. Here's a much simpler version of the CreationFilter in VB:

Public Class ScrollbarUIElementCreationFilter : Implements IUIElementCreationFilter

    Private _scrollBarWidth As Integer
    Public Sub New(ByVal scrollBarWidth As Integer)

        _scrollBarWidth = scrollBarWidth
    End Sub

    Public Sub AfterCreateChildElements(ByVal parent As Infragistics.Win.UIElement) Implements Infragistics.Win.IUIElementCreationFilter.AfterCreateChildElements

        If TypeOf parent Is ValueListDropDownUIElement Then
            For Each element As UIElement In parent.ChildElements
                If TypeOf element Is ValueListItemContainerUIElement Then
                    element.Rect = New Rectangle(element.Rect.X, element.Rect.Y, parent.Rect.Width - Me._scrollBarWidth, element.Rect.Height)
                ElseIf TypeOf element Is ScrollBarUIElement Then
                    element.Rect = New Rectangle(parent.Rect.Right - Me._scrollBarWidth, element.Rect.Y, Me._scrollBarWidth, element.Rect.Height)
                End If
            Next
        End If

    End Sub

    Public Function BeforeCreateChildElements(ByVal parent As Infragistics.Win.UIElement) As Boolean Implements Infragistics.Win.IUIElementCreationFilter.BeforeCreateChildElements
        Return False
    End Function
End Class

I also changed it so that the constructor takes in the width you want the scrollbars to be, not the width of the remaining area.

Hi Mike,

thank you for your help.

The reason Georgi's sample is so complicated is because I asked how to get up and down buttons to be taller - see his image above.

With the code you kindly provided, the up and down buttons are even shorter than normal - see the image I attached.

My users are used to poke at the up and down buttons, and it is hard to educate them as they work three shifts and mostly computer illiterate.

I would appretiate your help in this.

Thanks,

Helen.

here is a larger image of the combo box.

Okay, then you have to rearrange some other elements, too.

Public Sub AfterCreateChildElements(ByVal parent As Infragistics.Win.UIElement) Implements Infragistics.Win.IUIElementCreationFilter.AfterCreateChildElements

        If TypeOf parent Is ValueListDropDownUIElement Then
            For Each element As UIElement In parent.ChildElements
                If TypeOf element Is ValueListItemContainerUIElement Then
                    element.Rect = New Rectangle(element.Rect.X, element.Rect.Y, parent.Rect.Width - Me._scrollBarWidth, element.Rect.Height)
                ElseIf TypeOf element Is ScrollBarUIElement Then
                    element.Rect = New Rectangle(parent.Rect.Right - Me._scrollBarWidth, element.Rect.Y, Me._scrollBarWidth, element.Rect.Height)
                End If
            Next
        End If

        If TypeOf parent Is ScrollBarUIElement Then
            For Each element As UIElement In parent.ChildElements

                If TypeOf element Is ScrollButtonUIElement Then
                    Dim scrollButtonUIElement As ScrollButtonUIElement = DirectCast(element, ScrollButtonUIElement)
                    If scrollButtonUIElement.ScrollButtonType = ScrollButton.Up Then
                        element.Rect = New Rectangle(element.Rect.X, element.Rect.Y, element.Rect.Width, Me._buttonHeight)
                    ElseIf scrollButtonUIElement.ScrollButtonType = ScrollButton.Down Then
                        element.Rect = New Rectangle(element.Rect.X, parent.Rect.Bottom - Me._buttonHeight, element.Rect.Width, Me._buttonHeight)
                    End If
                ElseIf TypeOf element Is ScrollTrackUIElement Then
                    element.Rect = New Rectangle(element.Rect.X, parent.Rect.Top + Me._buttonHeight, element.Rect.Width, parent.Rect.Height - (Me._buttonHeight * 2))
                End If
            Next
        End If

    End Sub

Mike,

thank you very very much for your help!

Your code works beautifully!

In case anyone wants the complete code, I attached the solution.

Helen.
