How to: Hide Individual Rows and Columns

  • 3 minutes to read

The following example demonstrates how to hide particular rows and columns by handling the CustomFieldValueCells event.In this example, the event handler iterates through all row headers and removes rows that correspond to the "Employee B" field value, and that are not Total Rows.

Imports Microsoft.VisualBasic
Imports System.Globalization
Imports System.Windows
Imports DevExpress.Xpf.PivotGrid

Namespace DXPivotGrid_HidingColumnsAndRows
    Partial Public Class Window1
        Inherits Window
        Public Sub New()
            AddHandler pivotGrid.CustomFieldValueCells, AddressOf pivotGrid_CustomFieldValueCells
        End Sub
        Private Sub Window_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
            pivotGrid.DataSource = PivotHelper.GetDataTable()
        End Sub

        ' Handles the CustomFieldValueCells event to remove
        ' specific rows.
        Private Sub pivotGrid_CustomFieldValueCells(ByVal sender As Object, _
                                                    ByVal e As PivotCustomFieldValueCellsEventArgs)
            If pivotGrid.DataSource Is Nothing Then
            End If
            If rbDefault.IsChecked = True Then
            End If

            ' Iterates through all row headers.
            For i As Integer = e.GetCellCount(False) - 1 To 0 Step -1
                Dim cell As FieldValueCell = e.GetCell(False, i)
                If cell Is Nothing Then Continue For

                ' If the current header corresponds to the "Employee B"
                ' field value, and is not the Total Row header,
                ' it is removed with all corresponding rows.
                If Object.Equals(cell.Value, "Employee B") AndAlso _
                        cell.ValueType <> FieldValueType.Total Then
                End If
            Next i
        End Sub

                                                    ByVal e As PivotFieldDisplayTextEventArgs)
            If Object.Equals(e.Field, pivotGrid.Fields(PivotHelper.Month)) Then
                e.DisplayText = _
            End If
        End Sub
        Private Sub rbDefault_Checked(ByVal sender As Object, ByVal e As RoutedEventArgs)
