New Post: DataGridControl Speed Improvement Suggestions?

Hi BoucherS,

I'm pretty sure we are trying to use the DataGrid in a way it wasn't meant to be used, unfortunately. We're trying to adapt the DataGrid to replace a simple, generic ListView control, with plans to expand the functionality afterward.

The majority of the logic that controls this grid is still in the C++ application which consumes the grid. But, if it helps, here is my XAML file:

<UserControl x:Class="WPFControls.DataTable"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"
             mc:Ignorable="d" 
             d:DesignHeight="400" d:DesignWidth="400">
    <Grid>
        <Grid.Resources>
            <DataTemplate x:Key="datatablecelltemplate">
                <Border Background="{Binding Background, UpdateSourceTrigger=PropertyChanged}">
                    <TextBlock TextTrimming="None" Text="{Binding Text, UpdateSourceTrigger=PropertyChanged}" Foreground="{Binding Foreground, UpdateSourceTrigger=PropertyChanged}">
                    </TextBlock>
                </Border>
            </DataTemplate>
<Style TargetType="{x:Type xcdg:ColumnManagerCell}">
                <Setter Property="HorizontalContentAlignment" Value="Center" />
                <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ColumnManagerCellPreviewMouseLeftButtonDownHandler"/>
            </Style>

            <Style TargetType="{x:Type xcdg:DataCell}">
                <Setter Property="ContentTemplate" Value="{StaticResource datatablecelltemplate}" />
                <EventSetter Event="MouseRightButtonDown" Handler="DataCellMouseRightButtonDownHandler"/>
                <EventSetter Event="MouseLeftButtonUp" Handler="DataCellMouseLeftButtonUpHandler"/>
                <EventSetter Event="MouseDoubleClick" Handler="DataCellMouseDoubleClickHandler"/>
                <Setter Property="Padding" Value="0"/>
            </Style>

            <Style TargetType="{x:Type xcdg:TableViewScrollViewer}">
                <Setter Property="CanContentScroll" Value="false" />
            </Style>
        </Grid.Resources>

        <xcdg:DataGridControl x:Name="dg" AutoCreateColumns="True" SelectionUnit="Cell" SelectionMode="Extended" ReadOnly="True" ItemsSource="{Binding dataGridCollectionView}"  ScrollViewer.ScrollChanged="myGrid_ScrollChanged" ScrollViewer.IsDeferredScrollingEnabled ="false">
