                                  • I have bind Chart (silverlight) with Dev X PivotGrid and Pivot Grid with SSAS Cube(Multi dimentional data).

                                    My Pivot grid has 18000 record with 6 columns.

                                    If i select few records in Pivot Grid , it works fine.

                                    If i select all record in Pivot Grid, I am getting following Error message.

                                    "
                                    System.OutOfMemoryException was unhandled
                                    Message: An unhandled exception of type 'System.OutOfMemoryException' occurred in Unknown Module."

                                    What could be solution of above issue ? You early reply will appreciated.

                                I regret to inform you that this issue is related to constraints of MS Silverlight framework. There is no built-in capability to place more then 30000 visual elements on the canvas. Each bar or point element is presented as a visual control group.
                                As an immediate solution, use Line Series to visualize large data sets. In this case, each line point will not be represented as a visual control group.

                                  It able to show in Pirvot grid. What could be wrong in Chart.
                                  Can you provide me some sample code ?

                                  You can use your code. Set the Diagram.SeriesTemplate property to LineSeries2D to display a Line chart. To improve performance, you can reduce the number of visual objects - axis and point labels, point markers, and so on.
                                  Additionally, please review our online ChartIntegration demo. This demo demonstrates how to change the type of series at runtime.

                                  Hi Chad,

                                  Please confirm that you have excluded axis labels, point labels and point marker elements from the chart diagram. Review the following sample code snippet:

                                  <dxc:ChartControl.Diagram>
                        <dxc:XYDiagram2D x:Name="diagram">
                            <dxc:XYDiagram2D.SeriesTemplate>
                                <dxc:LineSeries2D MarkerVisible="False" LabelsVisibility="False">
                                    <dxc:LineSeries2D.Label>
                                        <dxc:SeriesLabel />
                                    </dxc:LineSeries2D.Label>
                                </dxc:LineSeries2D>
                            </dxc:XYDiagram2D.SeriesTemplate>
..
