18 Nov 20182 minutes to read

You can open the navigation popup programmatically by passing a HierarchyNavigatorItem to the ShowNavigationPopupItems method.

  • C#
    • HierarchyNavigator hierarchyNavigator = new HierarchyNavigator();
hierarchyNavigator.ShowNavigationPopupItems(hierarchyItem);

    The NavigationPopupOpening event occurs when the navigation popup is about to open.

    <syncfusion:HierarchyNavigator
    NavigationPopupOpening="NavigationPopupOpening" />
    HierarchyNavigator hierarchyNavigator = new HierarchyNavigator();
hierarchyNavigator.NavigationPopupOpening += NavigationPopupOpening;

private void NavigationPopupOpening(object sender, EventArgs e)
{
    // Occurs when the navigation popup is about to open.
}

    The NavigationPopupOpened event occurs after the navigation popup has been opened.

    <syncfusion:HierarchyNavigator
    NavigationPopupOpened="NavigationPopupOpened" />
    HierarchyNavigator hierarchyNavigator = new HierarchyNavigator();
hierarchyNavigator.NavigationPopupOpened += NavigationPopupOpened;

private void NavigationPopupOpened(object sender, EventArgs e)
{
    // Occurs when the navigation popup is opened.
}

    The NavigationPopupClosing event occurs when the navigation popup is about to close.

    <syncfusion:HierarchyNavigator
    NavigationPopupClosing="NavigationPopupClosing" />
    HierarchyNavigator hierarchyNavigator = new HierarchyNavigator();
hierarchyNavigator.NavigationPopupClosing += NavigationPopupClosing;

private void NavigationPopupClosing(object sender, EventArgs e)
{
    // Occurs when the navigation popup is about to close.
}

    The NavigationPopupClosed event occurs after the navigation popup has been closed.

    <syncfusion:HierarchyNavigator
    NavigationPopupClosed="NavigationPopupClosed" />
    HierarchyNavigator hierarchyNavigator = new HierarchyNavigator();
hierarchyNavigator.NavigationPopupClosed += NavigationPopupClosed;

private void NavigationPopupClosed(object sender, EventArgs e)
{
    // Occurs when the navigation popup is closed.
}
