Event Data

The CustomChartDataSourceData event's data class is PivotCustomChartDataSourceDataEventArgs. The following properties provide information specific to this event:

Property Description
CellInfo Gets an object which contains information about a PivotGrid control’s cell, whose value should be displayed in a ChartControl.
FieldValueInfo Gets an object which contains information about a field value to be displayed in a ChartControl.
ItemDataMember Gets the type of a chart data member that will represent the current pivot grid item.
ItemType Gets the type of a PivotGrid control’s item to be represented in a ChartControl.
Value Gets or sets a value to be displayed in a ChartControl.


The following example demonstrates how to add custom text to data prepared by the PivotGridControl, to display it in a ChartControl.

For this, it is necessary to handle the PivotGridControl.CustomChartDataSourceData event. In this event handler, you can determine the item type via the PivotCustomChartDataSourceDataEventArgs.ItemType property and change the PivotCustomChartDataSourceDataEventArgs.Value according to your custom requirements.

View Example

Private Sub pivotGridControl1_CustomChartDataSourceData(ByVal sender As Object, _
                              ByVal e As PivotCustomChartDataSourceDataEventArgs) _
                          Handles pivotGridControl1.CustomChartDataSourceData
    If e.ItemType = PivotChartItemType.RowItem Then
        If e.FieldValueInfo.Field Is fieldCategoryName Then
            e.Value = CategoryEncodeTable(e.FieldValueInfo.Value.ToString())
        ElseIf e.FieldValueInfo.Field Is fieldProductName Then
            Dim product As String = ProductEncodeTable(e.FieldValueInfo.Value.ToString())
            Dim category As String = CategoryEncodeTable(e.FieldValueInfo.GetHigherLevelFieldValue(fieldCategoryName).ToString())
            e.Value = product & "["c & category & "]"c
        End If
    End If
    If e.ItemType = PivotChartItemType.ColumnItem Then
        If e.FieldValueInfo.ValueType = PivotGridValueType.GrandTotal Then
            e.Value = "Total Sales"
        End If
    End If
    If e.ItemType = PivotChartItemType.CellItem Then
        e.Value = Math.Round(Convert.ToDecimal(e.CellInfo.Value), 0)
    End If
End Sub
