DataNavigator Class

The control that enables navigation through records in a data source and provides common record operations.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v24.2.dll

Declaration

C#

public class DataNavigator :
    NavigatorBase,
    IDataNavigatorOwner

VB.NET

Public Class DataNavigator
    Inherits NavigatorBase
    Implements IDataNavigatorOwner

Remarks

The DataNavigator control is used to navigate through records in a data source and perform operations against the data. It is derived from the NavigatorBase class, and so it inherits properties and methods common to all data navigation controls.

View Example: How to Bind Data Navigator to a Shared Source

The data navigator displays built-in buttons that enable a user to scroll forward or backward through records one at a time, go to the first record, go to the last record, insert a new record, post data changes, cancel data changes and delete a record. You can also add custom buttons, when required. To access built-in and custom buttons, use the DataNavigator.Buttons property. To perform custom actions on button clicks, handle the NavigatorBase.ButtonClick event.

The DataNavigator control needs to be associated with a data source in order to receive and manipulate data. Use the DataNavigator.DataSource and DataNavigator.DataMember properties for binding.

The DataNavigator can display a text string that specifies the current record and the total record count in the associated data source. Use the NavigatorBase.TextLocation and NavigatorBase.TextStringFormat to customize the display of this text.

Example

The following code shows how to create a new DataNavigator control, bind it to a data source and specify custom images for the control’s buttons at runtime. The custom images are stored in an ImageCollection object.

C#

using DevExpress.XtraEditors;

private void CreateDataNavigator() {
    // Create a new DataNavigator control
    DataNavigator dataNavigator = new DataNavigator();
    Controls.Add(dataNavigator);
    dataNavigator.Height = 40;
    dataNavigator.Dock = DockStyle.Bottom;
    // Bind to a data source
    dataNavigator.DataSource = productsBindingSource;
    // Specify the ImageCollection that stores custom images for the DataNavigator's buttons
    dataNavigator.Buttons.ImageList = imageCollection1;
    for (int i = 0; i < dataNavigator.Buttons.ButtonCollection.Count; i++) {
        dataNavigator.Buttons.ButtonCollection[i].ImageIndex = i;
    }
    dataNavigator.ShowToolTips = true;
}

VB.NET

Imports DevExpress.XtraEditors

Private Sub CreateDataNavigator()
   ' Create a new DataNavigator control
   Dim DataNavigator As New DataNavigator()
   Controls.Add(DataNavigator)
   DataNavigator.Dock = DockStyle.Bottom
   dataNavigator.Height = 40
   ' Bind to a data source
   DataNavigator.DataSource = productsBindingSource
   ' Specify the ImageCollection that stores custom images for the DataNavigator's buttons
   DataNavigator.Buttons.ImageList = imageCollection1
   Dim i As Integer
   For i = 0 To DataNavigator.Buttons.ButtonCollection.Count - 1
      DataNavigator.Buttons.ButtonCollection(i).ImageIndex = i
   Next i
   DataNavigator.ShowToolTips = True
End Sub
