BreadCrumbEdit.GoUp() Method

Navigates to the currently selected node’s parent node.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v23.2.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

public void GoUp()

VB.NET

Public Sub GoUp

Remarks

The GoUp method navigates to a BreadCrumbNode that contains the currently selected node in its BreadCrumbNode.ChildNodes collection.

You can use the built-in Breadcrumb Editor history to navigate back and forth through history items. To do this, use BreadCrumbEdit.GoBack and BreadCrumbEdit.GoForward methods.

Read the following topic for additional information: Breadcrumb Edit Control.

Example

The following example implements forward and backward navigation through history in the Breadcrumb editor:

C#

using System;

namespace DXApplication {
    public partial class Form1 : DevExpress.XtraEditors.XtraForm {
        public Form1() {
            InitializeComponent();
            UpdateButtonStates();
            breadCrumbEdit1.SelectedNodeChanged += BreadCrumbEdit1_SelectedNodeChanged;
        }

        void BreadCrumbEdit1_SelectedNodeChanged(object sender, DevExpress.XtraEditors.BreadCrumbSelectedNodeChangedEventArgs e) {
            UpdateButtonStates();
        }

        void buttonBack_Click(object sender, EventArgs e) {
            breadCrumbEdit1.GoBack();
        }

        void buttonForward_Click(object sender, EventArgs e) {
            breadCrumbEdit1.GoForward();
        }

        void buttonUp_Click(object sender, EventArgs e) {
            breadCrumbEdit1.GoUp();
        }
        void UpdateButtonStates() {
            buttonBack.Enabled = breadCrumbEdit1.CanGoBack;
            buttonForward.Enabled = breadCrumbEdit1.CanGoForward;
            buttonUp.Enabled = breadCrumbEdit1.CanGoUp;
        }
    }
}
