map zoom error since Q3

[Tamas]

Hi,

I was drawing charts on a RadMap like in your City demographics example. That was working fine until I've upgraded to the latest Q3 version. Now I have an issue when zooming: the small charts are enlarged when zooming in and when the zoom is finished they are resized again. This was not like this with the version before, when the radcharts had a constant size.

Here is my code:

        private void InitializeChart(RadChart chart, List<LabeledCell> cells, Telerik.Windows.Controls.Map.Location location)

        {

            this.SetChartDimension(chart);

 

            chart.BorderThickness = new Thickness(0);

            chart.DefaultView.ChartArea.Background = new SolidColorBrush(Colors.Transparent);

            chart.DefaultView.ChartArea.Padding = new Thickness(0);

            chart.Background = new SolidColorBrush(Colors.Transparent);

            chart.DefaultView.ChartLegend.Visibility = Visibility.Collapsed;

            chart.DefaultView.ChartTitle.Visibility = Visibility.Collapsed;

            chart.DefaultSeriesDefinition = new PieSeriesDefinition() { ShowItemLabels = false };

            chart.Margin = new Thickness(-1 * (chart.Width / 2), -1 * (chart.Height / 2), 0, 0);

             

            List<double> chartdata = new List<double>();

            foreach (LabeledCell cell in cells)

            {

                chartdata.Add(Double.Parse(cell.Value.ToString()));

            }

 

            chart.ItemsSource = chartdata;

            chart.SetValue(MapLayer.LocationProperty, location);

            this.InformationLayer.Items.Add(chart);

        }

      

private void SetChartDimension(RadChart chart)
{
    if (this.RadMap1.ZoomLevel < 0)
        return;

    chart.Height = 30 * this.RadMap1.ZoomLevel;
    chart.Width  = 30 * this.RadMap1.ZoomLevel;
}

And the XAML:

<telerik:RadMap x:Name="RadMap1" ZoomLevel="2">
    <telerik:InformationLayer x:Name="InformationLayer" Visibility="Visible">
        <telerik:InformationLayer.MapControl>
            <telerik:RadMap Background="Transparent" Foreground="Transparent" />
        </telerik:InformationLayer.MapControl>
    </telerik:InformationLayer>
</telerik:RadMap>

Is it possible to achieve the original behavior?

Many thanks and best regards,
