FeatureDataForm scrollviewer -- bug?

JudyTroutwine

The xaml below seems straightforward; however, the scrollviewer for the FeatureDataForm shows only the vertical bar. There are some wide fieds on the table records being partially displayed, and I tried various widths and heights for the form -- still no horizontal bar. Also, hiding the vertical bar has no effect -- it is still visible. Is this a bug?

<Border x:Name="FDFBorder" Visibility="Collapsed" Canvas.ZIndex="10" Grid.Row="2" IsHitTestVisible="True"
            Grid.Column="0" Grid.ColumnSpan="3" Background="Transparent" CornerRadius="10"
            HorizontalAlignment="Left" VerticalAlignment="Top" Margin="10,10,0,0" Width="300" Height="400"

<ScrollBar x:Name="HorizontalScrollBar" Grid.Column="0" Height="15" IsTabStop="False" Maximum="{TemplateBinding ScrollableWidth}" Margin="-1,0,-1,-1" Minimum="0" Orientation="Horizontal" Grid.Row="1" Visibility="Visible" Value="{TemplateBinding HorizontalOffset}" ViewportSize="{TemplateBinding ViewportWidth}"/>

There is not an "Auto" value allowed in this context.

You have to set HorizontalScrollBarVisibility="Auto" on the ScrollViewer (not on the ScrollBar)

<ScrollViewer Style="{StaticResource CustomScrollViewerStyle}" IsTabStop="False"          Background="{x:Null}" Padding="{TemplateBinding Padding}"          VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">     <ContentPresenter x:Name="ContentPresenter" Margin="12,12,6,12"/> </ScrollViewer>

The FeatureDataGrid Xaml is in the FeatureDataGrid.Theme.xaml file of the toolkit

JudyTroutwine

That said, I would like to customize the textboxes for other reasons. The provided toolkit code does not include the xaml for the FeatureDataGrid. Is it available somewhere?

JudyTroutwine

That solves it. Thanks.

Dominique,

I have a copy of the FeatureDataForm style resource. I used that and simply edited thus

<ScrollBar x:Name="HorizontalScrollBar" Grid.Column="0" Height="15" IsTabStop="False" Maximum="{TemplateBinding ScrollableWidth}" Margin="-1,0,-1,-1" Minimum="0" Orientation="Horizontal" Grid.Row="1" Visibility="Visible" Value="{TemplateBinding HorizontalOffset}" ViewportSize="{TemplateBinding ViewportWidth}"/>

There is not an "Auto" value allowed in this context. The bar is now visible though with no slider. It seems something must be done to activate the bar. Perhaps widening the textboxes in the FeatureDataForm would do the trick. Can that be added to the style?

DominiqueBroux

I don't know if it's a bug but by default the HorizontalScrollbarVisibility is not visible.

To change that you have to retemplate the FeatureDataForm.

You can use Expression Blend and right-click on your FeatureDataForm and select "Edit Template" --> "Edit a copy...", then you will get the default control template.
Look for the ScrollViewer and add HorizontalScrollBarVisibility="Auto"
