Camera extension to RadChart works the first time and not on setting the item source later

Hello there,

I have a rad chart which takes the definition as below :

<telerik:RadChart x:Name="rd3DChart" IsManipulationEnabled="True" Height="250" Margin="5,5,5,5" Grid.Row="4" Grid.Column="0" Grid.ColumnSpan="3">
<telerik:RadChart.DefaultView>
<telerik:ChartDefaultView>
</telerik:ChartDefaultView>
</telerik:RadChart.DefaultView>
<telerik:RadChart.SeriesMappings>
<telerik:SeriesMapping>
<telerik:SeriesMapping.SeriesDefinition>
<telerik:Pyramid3DSeriesDefinition ShowItemLabels="True" ItemLabelFormat="#YValue" ShowItemToolTips="True" ItemToolTipFormat="#XValue - #YValue">
</telerik:Pyramid3DSeriesDefinition>
</telerik:SeriesMapping.SeriesDefinition>
<telerik:SeriesMapping.ItemMappings>
<telerik:ItemMapping FieldName="YValue"
DataPointMember="YValue" />
<telerik:ItemMapping FieldName="XValue"
DataPointMember="Label" />
</telerik:SeriesMapping.ItemMappings>
</telerik:SeriesMapping>
</telerik:RadChart.SeriesMappings>
</telerik:RadChart>

I have a function which binds the values to the chart like :

private void PopulateAggregationChart()
{
rdAggregateExpanderGraph.Visibility = System.Windows.Visibility.Visible;

List<AggregateChartItem> charItems = new List<AggregateChartItem>();
AggregateChartItem temp = null;

rd3DChart.ItemsSource = null;

charItems = GetItemsToBindToChart();

CameraExtension cam = new CameraExtension();
cam.ZoomEnabled = true;
if (rd3DChart.DefaultView.ChartArea.Extensions.Count == 0)
rd3DChart.DefaultView.ChartArea.Extensions.Add(cam);

rd3DChart.ItemsSource = charItems;

}

I have added a check here on the extensions as clearing it and adding it again threw null reference exception. My Binding works the first time, but when I call this function to bind the graph with a different set of data, the graph is being painted as expected, but the camera extension is not applied to it.

Please help in how I can retain the camera extension throughout.

WeekViewDefinition Group Size Problem

Hi,

I have recently added filtering of resources on my WeekViewDefinition view.

When there are 8 resources the layout looks fine, each day of the week for each resource is a good size. See Good.jpg

If I filter one of the resources, each day of the week gets resized and becomes way too large. See Bad.jpg.

Any help would be appreciated as the view is unusable when the days become so large.

Thanks

Anthony

Can't bind foreground color of cell programatically

Hello,

I need to create columns of RadGridView dynamically, so I have to style the cell in code. Here is my code:

1.<telerik:RadGridView x:Name="ResultsGridView" Grid.Row="1" Grid.Column="0" Margin="10" ItemsSource="{Binding ResultsG}" AutoGenerateColumns="False" RowHeight="25" EnableColumnVirtualization="True" IsReadOnly="True"/>

01.foreach (vstupni_zdroj inputSource in inputSources)

02.{

03. GridViewDataColumn col = new GridViewDataColumn

04. {

05. Header = inputSource.name_short,

06. UniqueName = inputSource.name_short.ToLower()

07. };

08.

09. DataTemplate template = new DataTemplate();

10. var cell = new FrameworkElementFactory(typeof(Telerik.Windows.Controls.Label));

11.

12. Binding cellBindText = new Binding("InputSources[" + inputSource.id_vstupni_zdroj + "]");

13. cellBindText.Converter = new TextConverter();

14. cell.SetBinding(Telerik.Windows.Controls.Label.ContentProperty, cellBindText);

15.

16. Binding cellBindColor = new Binding("InputSources[" + inputSource.id_vstupni_zdroj + "]");

17. cellBindColor.Converter = new StringToBrushConverter();

18. cell.SetBinding(Telerik.Windows.Controls.Label.ForegroundProperty, cellBindColor);

19.

20. Binding cellBindColorB = new Binding("InputSources[" + inputSource.id_vstupni_zdroj + "]");

21. cellBindColor.Converter = new StringToBrushConverter();

22. cell.SetBinding(Telerik.Windows.Controls.Label.BackgroundProperty, cellBindColorB);

23.

24. template.VisualTree = cell;

25. template.Seal();

26.

27. col.CellTemplate = template;

28. ResultsGridView.Columns.Add(col);

29.}

The list named InputSources is Dictionary<uint, string> which contains ID and some color in string. StringToBrushConverter converts string to Brush using this code:

01.SolidBrush brush;

02.if (value is string)

03.{

04. switch (value as string)

05. {

06. case "red":

07. brush = new SolidBrush(System.Drawing.Color.Red);

08. break;

09. case "green":

10. brush = new SolidBrush(System.Drawing.Color.Green);

11. break;

12. default:

13. brush = new SolidBrush(System.Drawing.Color.Black);

14. break;

15. }

16. return brush;

17.}

18.return value;

My problem is that the foreground color of the label does not change, but background does, even if the approach is the same for both. So I'd like to know, what am I doing wrong.

Thank you for any help.
Kate

Is converter on ValueBinding possible?

Hello All,

I was just wondering if there is a way to support the following with the RadCartesianChart:

In my example, I am binding the vertical axis to an "Altitude" property on my underlying data. The data is in meters. Based on an application setting, I would like the ability to convert the value to feet when needed.

I do have access to the data contract and I can add another property for feet, however I was just wondering if I could avoid the multiple properties.

Thanks,
Chris

RadMap not loading Bing Tiles (Intermittently)

We have a solution that has been in production at multiple sites for about 11 months. It is using v2012.2.607.40 of the controls. A few weeks ago one of our sites started reporting and issue where the map tiles were not loading.

It seems to be intermittent at best. If the application loads tiles on startup it appears to function properly for the lifetime of the session. If the tiles do not load on startup it does not load them for the lifetime of the session.

We see the initial request go out the door to authenticate to Bing and the Tile Service addressed returned. We never see the Tile Request happen if the client is in the "failed" state.

Any information on where to look for a possible network issue would be greatly appreciated. We are not seeing any errors return by RadMap, just a gray screen signifying that no tiles have loaded.

Thanks,

Rick Adair
