GridControl.EmbeddedNavigator Property

Allows to customize the embedded data navigator.

Namespace: DevExpress.XtraGrid

Assembly: DevExpress.XtraGrid.v23.2.dll

NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation

Declaration

C#

[DXCategory("Appearance")]
public virtual ControlNavigator EmbeddedNavigator { get; }

VB.NET

<DXCategory("Appearance")>
Public Overridable ReadOnly Property EmbeddedNavigator As ControlNavigator

Property Value

Type	Description
ControlNavigator	The data navigator.

Remarks

Set the GridControl.UseEmbeddedNavigator property to true to enable the data navigator. The grid control displays the data navigator at the bottom. Use the EmbeddedNavigator property to customize the data navigator’s settings. You can display or hide certain command buttons, customize their appearance settings and hints.

Run Demo

Enable, Disable Command Buttons

You can also use the Grid’s ColumnViewOptionsBehavior.AllowAddRows and ColumnViewOptionsBehavior.AllowDeleteRows options to enable or disable the “Append” and “Delete” buttons.

The enabled state of specific buttons (for example, End Edit, Cancel Edit) is controlled automatically and cannot be changed using the button’s Enabled property. For example, the Grid automatically enables the “End Edit” button (that posts the edit value to a data source) when a user activates a cell’s editor, and disables the button when the cell editor closes.

Handle Button Clicks

The following example demonstrates how to display a confirmation message after a user clicks the “Remove” command button and allow to cancel the action:

C#

using System.Windows.Forms;
using DevExpress.XtraEditors;

public Form1() {
    InitializeComponent();
    // Binds the Grid control to a data source.
    gridControl1.DataSource = GetData();
    // Handles clicks on data navigator buttons.
    gridControl1.EmbeddedNavigator.ButtonClick += EmbeddedNavigator_ButtonClick;
}
private void EmbeddedNavigator_ButtonClick(object sender, NavigatorButtonClickEventArgs e) {
    if(e.Button.ButtonType == NavigatorButtonType.Remove)
        e.Handled = XtraMessageBox.Show("Do you want to delete the record?", "Warning", MessageBoxButtons.YesNo) == DialogResult.No;
}

VB.NET

Imports System.Windows.Forms
Imports DevExpress.XtraEditors

Public Sub New()
    InitializeComponent()
    ' Binds the Grid control to a data source.
    gridControl1.DataSource = GetData()
    ' Handles clicks on data navigator buttons.
    AddHandler gridControl1.EmbeddedNavigator.ButtonClick, AddressOf EmbeddedNavigator_ButtonClick
End Sub
Private Sub EmbeddedNavigator_ButtonClick(ByVal sender As Object, ByVal e As NavigatorButtonClickEventArgs)
    If e.Button.ButtonType = NavigatorButtonType.Remove Then
        e.Handled = XtraMessageBox.Show("Do you want to delete the record?", "Warning", MessageBoxButtons.YesNo) = DialogResult.No
    End If
End Sub

Note

You can also link an external ControlNavigator to the Grid control. Place the ControlNavigator control onto a Form and bind it to the Grid (ControlNavigator.NavigatableControl).

Example

In this example we change the visibility of two buttons of the embedded navigator: Append and Remove.

C#

    ControlNavigator navigator = gridControl1.EmbeddedNavigator;
    navigator.Buttons.BeginUpdate();
    try {
        navigator.Buttons.Append.Visible = false;
        navigator.Buttons.Remove.Visible = false;
    }
    finally {
        navigator.Buttons.EndUpdate();
    }

VB.NET

    Dim navigator As ControlNavigator = GridControl1.EmbeddedNavigator
    navigator.Buttons.BeginUpdate()
    Try
        navigator.Buttons.Append.Visible = False
        navigator.Buttons.Remove.Visible = False
    Finally
        navigator.Buttons.EndUpdate()
    End Try
