Context Menu

The context menu used by RadPivotGrid can be easily extended. It is a common requirement to add new items to the menu or modify the existing ones.

The PivotGridContextMenuBase.Context property provides information about the element triggering the Click event. The example below will evaluate the context so that we add an additional element whenever the menu opens after click on any of the pivot data cells.

Initialize and Set Custom Menu

public PivotGridConextMenuForm()
    MyPivotGridContextMenu menu = new MyPivotGridContextMenu(this.radPivotGrid1);
    this.radPivotGrid1.PivotGridElement.ContextMenu = menu;

Public Sub New()
    Dim menu As New MyPivotGridContextMenu(Me.radPivotGrid1)
    Me.radPivotGrid1.PivotGridElement.ContextMenu = menu
End Sub

Custom Context Menu Class

public class MyPivotGridContextMenu : PivotGridContextMenu
    public MyPivotGridContextMenu(RadPivotGrid pivotGrid)
        : base(pivotGrid.PivotGridElement)
    { }
    protected override void AdjustItemsForContext()
        if (this.Context is PivotCellElement)
            RadMenuItem customMenuItem = new RadMenuItem();
            customMenuItem.Text = "Export to Excel";
            RadMenuSeparatorItem separator = new RadMenuSeparatorItem();
            customMenuItem.Click += customMenuItem_Click;
    private void customMenuItem_Click(object sender, EventArgs e)
        RadMessageBox.Show("Export to Excel");

Public Class MyPivotGridContextMenu
    Inherits PivotGridContextMenu
    Public Sub New(pivotGrid As RadPivotGrid)
    End Sub
    Protected Overrides Sub AdjustItemsForContext()
        If TypeOf Me.Context Is PivotCellElement Then
            Dim customMenuItem As New RadMenuItem()
            customMenuItem.Text = "Export to Excel"
            Dim separator As New RadMenuSeparatorItem()
            AddHandler customMenuItem.Click, AddressOf customMenuItem_Click
        End If
    End Sub
    Private Sub customMenuItem_Click(sender As Object, e As EventArgs)
        RadMessageBox.Show("Export to Excel")
    End Sub
End Class
