Handle Navigation Popup Events

Passing the argument “HierarchyNavigator item” in a method called ShowNavigationPopupItems can open the Navigation Popup for the corresponding item passed in the method.

  • C#
    • HierarchyNavigator hierarchyNavigator = new HierarchyNavigator();

hierarchyNavigator.ShowNavigationPopupItems(hierarchyitem);

    NavigationPopupOpening occurs when the navigation pop-up window is in the process of opening.

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

private void NavigationPopupOpening(object sender, EventArgs e)<br>
{
<br>
    //Occurs when Navigation Popup attempt to open
<br>
}

    NavigationPopupOpened occurs when the navigation pop-up window is open.

    <syncfusion:HierarchyNavigator NavigationPopupOpened="NavigationPopupOpened"/>

HierarchyNavigator hierarchyNavigator = new HierarchyNavigator();<br>hierarchyNavigator.NavigationPopupOpened += new EventHandler(NavigationPopupOpened);
    private void NavigationPopupOpened(object sender, EventArgs e)<br>
{
<br>
    //Occurs when Navigation Popup is opened
}

    NavigationPopupClosing occurs when the navigation pop-up window is closing.

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

private void NavigationPopupClosing(object sender, EventArgs e)<br>
{<br>    
//Occurs when Navigation Popup is Closing
}

    NavigationPopupClosed occurs when the navigation pop-up window is closed.

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

private void NavigationPopupClosing(object sender, EventArgs e)<br>
