Hi,

 I have a DataGrid and I apply a style to the selector row which is defined below. This sets the border colour depending on the status of the data in the row.

          <Style x:Key="rowSelectorStyle" TargetType="{x:Type xcdg:RowSelector}">

            <Style.Setters>

                <EventSetter Event="MouseEnter" Handler="OnRowSelectorMouseEnter"/>

                <EventSetter Event="PreviewMouseLeftButtonDown" Handler="OnRowSelectorPreviewMouseLeftButtonDown"/>

                <Setter Property="BorderThickness" Value="1"/>

                <Setter Property="Margin" Value="1"/>

                <Setter Property="Padding" Value="2"/>

                <Setter Property="BorderBrush" >

                    <Setter.Value>

                        <MultiBinding Converter="{StaticResource fieldStatusToBrushConverter}">

                            <Binding Mode="OneWay" RelativeSource="{RelativeSource Self}" />

                            <Binding Mode="OneWay" RelativeSource="{RelativeSource Self}" Path="DataContext" />

                        </MultiBinding>

                    </Setter.Value>

                </Setter>

            </Style.Setters>

         </Style>

 This works fine until I sort the rows using the built in sort by clicking on a column. The causes the rows to be re-ordered but the style for each row does not seem to update to match the new position of the data.

If I force row recycling by scrolling the grid then it seems the style gets applied correctly i.e. the row selector border is applied to the correct rows.

 Is it possible to ensure the style gets refreshed when sorting rows? I have tried reapplying the style for each row on ItemsSourceChangeCompleted event but this does not resolve the issue.

 Many Thanks

 Pete 

Hi Pete,

Are you able to send me a small self-contained sample application that shows this behavior? With your code, I will be able to answer your question based off of your exact scenario. 

Hi,

Please find attached a simple test application that demonstrates the issue with the row selector style getting detached from the correct DataRow. The red border should be displayed  if the first column is empty – the first row  on startup.

 Sorting works at first but keep sorting and it’ll soon go wrong.

Thanks

 Pete
