I am trying to create a listview (5'000 items +) that has a smooth scrolling. I found a solution in the inet, that "virtualizationmode=Recycling" could do the trick.
Well I totally am lost, since I used a gridview in my old app. Now to virtualize the list I can not use gridview anymore, as I read in another post.
How can I bring that to work? I want to bind the items using an observalcollection and I need a Header.
Here is my old listview with gridview:
<ListView x:Name="ListView_Main" Grid.Column="4" Grid.RowSpan="18" BorderBrush="#FFE87E00" Foreground="#FFE87E00" Background="Transparent" VirtualizingStackPanel.IsVirtualizing="true" VirtualizingStackPanel.VirtualizationMode="Recycling">
<ListView.View>
<GridView x:Name="GridView_ListHeader" AllowsColumnReorder="False">
<!--CheckBox-->
<GridViewColumn x:Name="GridViewColumn_Check" Width="25" Header=""><GridViewColumn.CellTemplate><DataTemplate><StackPanel>
<!---Tag = Index-->
<CheckBox IsChecked="{Binding Checked}" Tag="{Binding Index}"/></StackPanel></DataTemplate></GridViewColumn.CellTemplate>
</GridViewColumn>
<!--CheckImage-->
<GridViewColumn x:Name="GridViewColumn_CheckFake" Width="25" Header=""><GridViewColumn.CellTemplate><DataTemplate><StackPanel>
<Grid Height="17" Width="17" VerticalAlignment="Center" HorizontalAlignment="center">
<Canvas Background="{Binding Color}" Margin="3" Cursor="Hand" Tag="{Binding Index}" MouseLeftButtonDown="Canvas_ListIcon_MouseLeftButtonDown" MouseEnter="Canvas_ListIcon_MouseEnter" MouseLeave="Canvas_ListIcon_MouseLeave"><Canvas.OpacityMask>
<ImageBrush Stretch="UniformToFill" ImageSource="{Binding ImageCheckbox}" RenderOptions.BitmapScalingMode="NearestNeighbor" RenderOptions.EdgeMode="Aliased"/></Canvas.OpacityMask></Canvas></Grid></StackPanel></DataTemplate></GridViewColumn.CellTemplate>
</GridViewColumn>
<!--Source-->
<GridViewColumn x:Name="GridViewColumn_Icon" Header="" Width="25"><GridViewColumn.CellTemplate><DataTemplate><StackPanel>
<Grid Height="17" Width="17" VerticalAlignment="Center" HorizontalAlignment="center">
<Canvas Background="{Binding Color}" Tag="{Binding Index}" Margin="3" MouseEnter="Canvas_SourceIcon_MouseEnter" MouseLeave="Canvas_SourceIcon_MouseLeave"><Canvas.OpacityMask>
<ImageBrush ImageSource="{Binding ImageSource}" Stretch="UniformToFill" RenderOptions.BitmapScalingMode="NearestNeighbor" RenderOptions.EdgeMode="Aliased"/></Canvas.OpacityMask></Canvas></Grid></StackPanel></DataTemplate> </GridViewColumn.CellTemplate>
</GridViewColumn>
<!--Pos-->
<GridViewColumn DisplayMemberBinding="{Binding Position}" x:Name="GridViewColumn_Pos" Width="50" Header="Pos"/>
<!--Entry-->
<GridViewColumn DisplayMemberBinding="{Binding Id}" x:Name="GridViewColumn_Entry" Width="200" Header="Eingabe"/>
<!--Sap-->
<GridViewColumn DisplayMemberBinding="{Binding SaperionNr}" x:Name="GridViewColumn_Sap" Width="100" Header="Saperion"/>
<!--Sup-->
<GridViewColumn DisplayMemberBinding="{Binding SupisNr}" x:Name="GridViewColumn_Sup" Width="100" Header="Navision"/>
<!--Path-->
<GridViewColumn DisplayMemberBinding="{Binding Path}" x:Name="GridViewColumn_Path" Width="150" Header="Pfad"/>
<!--Format-->
<GridViewColumn DisplayMemberBinding="{Binding Format}" x:Name="GridViewColumn_Format" Width="50" Header="Format"/>
<!--Page-->
<GridViewColumn DisplayMemberBinding="{Binding Page}" x:Name="GridViewColumn_Page" Width="40" Header="Blatt"/>
<!--Stat-->
<GridViewColumn DisplayMemberBinding="{Binding Status}" x:Name="GridViewColumn_Stat" Width="175" Header="Status"/>
</GridView>
</ListView.View>
</ListView>
Thank you in advance!!!
