Examples

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.

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
