How to expand all the members of a hierarchy in WPF OlapChart ?
1 min read
You can expand all the members of a hierarchy by setting the “DrillState” property of DimensionElement to “ExpandAll” as follows.
For example, a button has been created and in its click event, the dimension at the row, at first index, has been completely expanded and the control is refreshed.
C#
public MainWindow()
{
InitializeComponent();
this.olapGrid1.OlapDataManager = new
Syncfusion.Olap.Manager.OlapDataManager("Data
Source=http://bi.syncfusion.com/olap/msmdpump.dll;
Initial Catalog=Adventure Works DW 2008 SE;");
this.olapGrid1.OlapDataManager.SetCurrentReport(SampleReport());
}
private void btn_ExpandAll_Click(object sender, System.Windows.RoutedEventArgs e)
{ (this.olapGrid1.OlapDataManager.CurrentReport.SeriesElements[1].ElementValue as DimensionElement).DrillState = DrillState.ExpandAll;
this.olapGrid1.DataBind();
}
VB
Public Sub New()
InitializeComponent()
Me.olapGrid1.OlapDataManager = New
Syncfusion.Olap.Manager.OlapDataManager("Data
Source=http://bi.syncfusion.com/olap/msmdpump.dll; Initial Catalog=Adventure
Works DW 2008 SE;") Me.olapGrid1.OlapDataManager.SetCurrentReport(SampleReport())
End Sub
Private Sub btn_ExpandAll_Click(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs)
TryCast(Me.olapGrid1.OlapDataManager.CurrentReport.SeriesElements(1).
ElementValue, DimensionElement).DrillState = DrillState.ExpandAll
Me.olapGrid1.DataBind()
End Sub
