Hello,
I have upgraded RadControls version to RadControls for WPF-2010.3 1314 (Jan 14, 2011) in my WPF form and now the Texts in the Gridview header and rows are not wrapping properly. Please help to find out any property that can be used in design or code for the wrapping the text.

I found that the properties "TextAlignment" and "TextWrapping" is obselete in new Telerik version.

GridView.AlignmentContentPresenter is also obselete.

Thanks,
Sooraj

1 to N Series

I just started using the RadChart control and am attempting to create an XY scatter chart that displays matrix data that consists of row/column coordinates with a measurement value at each row/column location. Both the row and column are 1-to-n, so I don't know the upper bound size of each is until runtime. Here's the class representation of a single datapoint:

public class Measurement

{

public int Row { get; set; }

public int Column { get; set; }

public double Value { get; set; }

}

This is the method I'm using to create sample data that I am using to test this out with each row/series of data having multiple measurements:

private List<Measurement> CreateMeasurements()

{

// Create sample data

List<Measurement> measurements = new List<Measurement>();

measurements.Add(new Measurement() { Row = 2, Column = 1, Value = 130.5 });

measurements.Add(new Measurement() { Row = 2, Column = 2, Value = 135.0 });

measurements.Add(new Measurement() { Row = 2, Column = 3, Value = 133.0 });

measurements.Add(new Measurement() { Row = 2, Column = 4, Value = 127.0 });

measurements.Add(new Measurement() { Row = 2, Column = 5, Value = 120.0 });

measurements.Add(new Measurement() { Row = 3, Column = 1, Value = 140.5 });

measurements.Add(new Measurement() { Row = 3, Column = 2, Value = 150.5 });

measurements.Add(new Measurement() { Row = 3, Column = 5, Value = 135.0 });

measurements.Add(new Measurement() { Row = 3, Column = 6, Value = 133.2 });

measurements.Add(new Measurement() { Row = 4, Column = 2, Value = 145.5 });

measurements.Add(new Measurement() { Row = 4, Column = 3, Value = 155.5 });

measurements.Add(new Measurement() { Row = 4, Column = 5, Value = 160.5 });

measurements.Add(new Measurement() { Row = 4, Column = 6, Value = 165.8 });

return measurements;

}

What I am attempting to do is configure the chart declaratively in XAML, but I can't seem to figure out how to get a series for each row this way since it seems as though I need to know how many ItemMappings there will be beforehand. Here's the XAML I started with for the chart:

<telerik:RadChart HorizontalAlignment="Left" Margin="12,12,12,12" x:Name="XYScatterChart" VerticalAlignment="Top" >

<telerik:RadChart.SeriesMappings>

<telerik:SeriesMapping LegendLabel="Row">

<telerik:SeriesMapping.SeriesDefinition>

<telerik:LineSeriesDefinition/>

</telerik:SeriesMapping.SeriesDefinition>

<telerik:SeriesMapping.ItemMappings>

<telerik:ItemMapping DataPointMember="YValue" FieldName="Value"/>

<telerik:ItemMapping DataPointMember="XValue" FieldName="Column"/>

</telerik:SeriesMapping.ItemMappings>

</telerik:SeriesMapping>

</telerik:RadChart.SeriesMappings>

</telerik:RadChart>

This results in a single series for all of the data. Is there some way of doing this declaratively so it will know to create a SeriesMapping for each row of data that I have? Here's the solution I came up with using the code-behind, but I would much prefer to do it declaratively in XAML if it's possible.

public MainWindow()

{

InitializeComponent();

// Set chart source data

List<Measurement> measurements = CreateMeasurements();

XYScatterChart.ItemsSource = measurements;

// Get distinct row values

var rowValues = (from measurement in measurements

select measurement.Row).Distinct();

// Add series mappings

foreach (int rowValue in rowValues)

{

SeriesMappingCollection seriesMappings = XYScatterChart.SeriesMappings;

CreateSeriesMapping(XYScatterChart.SeriesMappings, rowValue);

}

private void CreateSeriesMapping(SeriesMappingCollection seriesMappings, int rowValue)

{

// Add a new mapping

SeriesMapping seriesMapping = new SeriesMapping();

seriesMappings.Add(seriesMapping);

// Set the legend label

seriesMapping.LegendLabel = String.Concat("Row ", rowValue.ToString());

// Set the series definition

seriesMapping.SeriesDefinition = new

LineSeriesDefinition();

// Add the filter descriptor

ChartFilterDescriptor filterDescriptor = new ChartFilterDescriptor();

filterDescriptor.Member = "Row";

filterDescriptor.Operator = FilterOperator.IsEqualTo;

filterDescriptor.Value = rowValue;

seriesMapping.FilterDescriptors.Add(filterDescriptor);

// Add the item mappings

ItemMappingCollection itemMappings = seriesMapping.ItemMappings;

itemMappings.Add(new ItemMapping("Column", DataPointMember.XValue));

itemMappings.Add(new ItemMapping("Value", DataPointMember.YValue));

}

I've included the image of what the graph looks like if it's of use. Thanks a lot for any suggestions.

Drag and drop between a Window and a Popup

I do not seem to be able to do it in WPF (in Silverlight it works fine).
Moreover, whenever I have an open popup (not for drag and drop), if I hover the mouse over it while doing a drag-and-drop operation the position of DragCue changes.
What do I do to get around these problems?
If I cannot use the WPF popup, are there any similar Rad controls that I can use instead?
Also I was trying to use RadWindow instead of a popup (even though popup is actually what we need) and it did not event allow me to drag the DragCue into it.
Please Help!!!!
Thanks
