Paging in WPF Olap Chart

6 May 20215 minutes to read

Paging in the OLAP chart supports you to load and render the large amount of data without any performance constraint.

A OLAP pager (user control) is included and bound with the OlapDataManager object of the OLAP chart. To enable paging, set the EnablePaging property to true.

When you process the large CellSet, it is split into several number of segments and each segment is assigned and rendered in a separate page. You can navigate back and forth in all possible ways by using the UI options in the OLAP pager. You can also change the page size and other pager settings at runtime by using the PageSetting window.

Include the following Syncfusion assembly from the installed location to add the OLAP pager (User Control) with OLAP chart.

• Syncfusion.OlapShared.Wpf

NOTE

You can also get the assemblies by browsing to the default assembly location: {System Drive}:\Program Files (x86)\Syncfusion\Essential Studio\<version number>\precompiledassemblies\<version number>\<framework version>\

Enable paging through XAML

            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <GroupBox  Header="OlapChart" Grid.Row="0">
            <syncfusion:OlapChart  Name="olapChart" Background="Transparent" SeriesStrokeThickness="0"></syncfusion:OlapChart>
            </GroupBox>
        <GroupBox Grid.Row="1" Header="OlapPager" Margin="5" >
            <pager:OlapPager x:Name="olapPager" ></pager:OlapPager>
        </GroupBox>
    </Grid>
</Window>

Enable paging through report

C#

using Syncfusion.Olap.Manager;
using Syncfusion.Olap.Reports;
namespace SampleApplication
{
	public partial class MainWindow : SampleWindow
	{
		private string _connectionString;
		private OlapDataManager _olapDataManager;
		public MainWindow()
		{  
			InitializeComponent();
			_connectionString = "Enter a valid connection string";
			//Created connection string is passed to OlapDataManager as argument
			_olapDataManager = new OlapDataManager(_connectionString);
			//Created OlapReport is set as a current report to OlapDataManager
			_olapDataManager.SetCurrentReport(SimpleDimensions());
			//Finally OlapChart control gets the data from the created OlapDataManager
			this.olapChart.OlapDataManager = _olapDataManager;
			this.olapChart.DataBind();
		}
		private OlapReport SimpleDimensions()
		{
			OlapReport olapReport = new OlapReport();
			olapReport.CurrentCubeName = "Adventure Works";
			olapReport.EnablePaging = true;
			olapReport.PagerOptions.CategorialPageSize = 10;
			olapReport.PagerOptions.SeriesPageSize = 10;
			DimensionElement dimensionElement = new DimensionElement() { Name = "Customer", HierarchyName = "Customer" };
			dimensionElement.AddLevel("Customer Geography", "Country");
			olapReport.CategoricalElements.Add(dimensionElement);
			MeasureElements measureElements = new MeasureElements();
			measureElements.Add(new MeasureElement { Name = "Internet Sales Amount" });
			olapReport.SeriesElements.Add(measureElements);
			dimensionElement = new DimensionElement() { Name = "Geography", HierarchyName = "Geography" };
			dimensionElement.AddLevel("Geography", "Country");
			olapReport.CategoricalElements.Add(dimensionElement);
			dimensionElement = new DimensionElement() { Name = "Date" };
			dimensionElement.AddLevel("Fiscal", "Fiscal Year");
			olapReport.SeriesElements.Add(dimensionElement);
			return olapReport;
		}
	}
}
