Thanks for the reply Petar.

I'm still having a problem. The scrollbars appear and the vertical scrollbar is on the left, but neither scrollbar acttually scrolls the content area.

I have attached an example program (a VS2008 solution). It generates random data to display in the grid. BTW. We are using v9.2 of Infragistics for WPF.

Could you confirm that you see the symptom?

Let's try again. The attached file is a regular zip (no password). It contains a VS2008 solution. The project shows a XamDataGrid, with the suggested styling. The project is linked with the Infragistics 2010v3 libraries.

The Grid is populated with randomly generated data so it contains more rows and columns than can be shown without scrollbars. Both scrollbars are present. The vertical scrollbar is on the left.

The problem is the scrollbars do not scroll the content area.

Interestingly - the tooltip scroll position indicator (I forget the proper name right now) does show as the vertical scrollbar is moved. It doesn't change value, but its does show.

I hope you will be able to diagnose the problem from this, Petar.

Thanks,

-Nigel.

Hi Nigel,

I looked through your sample and see what you mean. The thing is that in mine the vertical scrollbar works as it should, unlike the horizontal which is acting as yours. I am going to give this a more thorough search and probably forward it to our developers team for their assessment.

Thanks for your patience. I’ll get back to you shortly.

Regards Petar.

Petar,

I thought this was resolved but I find there isa further problem:

When the scrollbar is on the left, with many data rows in the grid, the scroll handle is too tall, and it only scrolls across the first 60 or so rows of the data. Also the scroll tooltip does not update during scrolling.

I have taken your example and extended the data generator to create 500 rows of data. I also added a checkbox at the top to trigger the "scrollbar on left" style. It starts off with the scrollbar on the right.

Observe: the height of the RH scroll handle, the ability to scroll thru all 500 rows of the data, and the updating of the scroller tooltip.

Now, check the "Scrollbar on Left" CheckBox. Observe: the scrollbar is now on the left, the height of the scroll handle is much greater than on the right, you can only scroll to row 56 or thereabouts, and the scroller tooltip does not update.

The new example is attached. Please let me know if you see the problem.

Thanks!

-Nigel.

Petar,

I'd appreciate an update on this when you have a moment.

Are you guys looking at it, or should we abandon the idea of moving the scrollbar to the LHS?

Thanks!

-Nigel.

I appear to have figured this out. The major problem with the previous suggestions was that you have to set CanContentScroll="True" on the ScrollContentPresenter.

There were a couple of of other minor issues. Here's the final result, which I am now using succesfully in our app:

     <Window.Resources>

        <ControlTemplate TargetType="ScrollViewer" x:Key="LeftVerticalScrollbar">

            <Grid Background="{TemplateBinding Background}">

                <Grid.RowDefinitions>

                    <RowDefinition Height="*"/>

                    <RowDefinition Height="Auto"/>

                </Grid.RowDefinitions>

                <Grid.ColumnDefinitions>

                    <ColumnDefinition Width="Auto"/>

                    <ColumnDefinition Width="*"/>

                </Grid.ColumnDefinitions>

                <ScrollContentPresenter x:Name="PART_ScrollContentPresenter"

                                        Grid.Column="1"

                                        Cursor="{TemplateBinding Cursor}"

                                        Margin="{TemplateBinding Margin}"

                                        ContentTemplate="{TemplateBinding ContentTemplate}"

                                        CanContentScroll="True"

                                        />

                <Rectangle Grid.Column="0" Grid.Row="1" Fill="#FFE9EEF4"/>

                <ScrollBar x:Name="PART_VerticalScrollBar"

                           Width="{TemplateBinding Width}"

                        IsTabStop="False"

                        Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}"

                        Grid.Column="0" Grid.Row="0"

                        Orientation="Vertical"

                        ViewportSize="{TemplateBinding ViewportHeight}"

                        Maximum="{TemplateBinding ScrollableHeight}"

                        Minimum="0"

                        Value="{TemplateBinding VerticalOffset}"

                        Margin="0"/>

                <ScrollBar x:Name="PART_HorizontalScrollBar"

                           Height="{TemplateBinding Height}"

                        IsTabStop="False"

                        Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}"

                        Grid.Column="1" Grid.Row="1" Orientation="Horizontal"

                        ViewportSize="{TemplateBinding ViewportWidth}"

                        Maximum="{TemplateBinding ScrollableWidth}"

                        Minimum="0"

                        Value="{TemplateBinding HorizontalOffset}"

                        Margin="0"/>

            </Grid>

        </ControlTemplate>

        <Style TargetType="ScrollViewer" >

            <Style.Triggers>

                <DataTrigger Binding="{Binding IsChecked, ElementName=LRCheckBox}"

                             Value="True">

                    <Setter Property="Template"

                            Value="{StaticResource LeftVerticalScrollbar}" />

                </DataTrigger>

            </Style.Triggers>

        </Style>

    </Window.Resources>

    <Grid>

        <Grid.RowDefinitions>

            <RowDefinition Height="Auto" />

            <RowDefinition Height="*" />

        </Grid.RowDefinitions>

        <CheckBox x:Name="LRCheckBox" Margin="5">ScrollBar on Left</CheckBox>

        <igDP:XamDataGrid Name="xamDataGrid1" Grid.Row="1"

                      DataSource="{Binding MyDataRecords}" Grid.RowSpan="2">

            <igDP:XamDataGrid.Resources>

            </igDP:XamDataGrid.Resources>

        </igDP:XamDataGrid>

    </Grid>

 I attach a VS2010 solution that demonstrates how this works.
