Reposition popup

[JustinTrody]

Hi, I am using the following wpf to create a popup when clicking on feature on map. The popup sometimes displays outside of the view window.

I would like to display the popup always in the centre of the map screen.  

Any ideas??

<esri:MapView.Overlays>

    <esri:OverlayItemsControl>

        <Grid x:Name="popup" Visibility="Visible"

          esri:MapView.ViewOverlayAnchor="{Binding Geometry}"

          IsHitTestVisible="False" HorizontalAlignment="Right" VerticalAlignment="Top" MaxWidth="200">

            <Grid.RowDefinitions>

                <RowDefinition Height="*" />

                <RowDefinition Height="20" />

            </Grid.RowDefinitions>

            <Grid.ColumnDefinitions>

                <ColumnDefinition Width="20" />

                <ColumnDefinition Width="*" />

            </Grid.ColumnDefinitions>

            <Border Background="#FFFFFF" BorderThickness="1,1,1,0" Margin="0,0,-33,19" BorderBrush="White" Grid.ColumnSpan="2" Grid.RowSpan="2">

                <StackPanel Margin="20" x:Name="MyStackPanel"/>

</Border>

        </Grid>

    </esri:OverlayItemsControl>

</esri:MapView.Overlays>

Have you considered using the ShowCalloutAt method instead? This will host your UI element and move it around to keep it on top of the map.

A more advanced method would be to create a custom control yourself to host your content, and have that implement IViewOverlay interface, which will give you the information needed to re-arrange the view yourself (this is also what the callout uses to do this).
