In this example:
- Enable the GridControl.UseEmbeddedNavigator property to display the Data Navigator within the Grid control.
- Use the GridControl.EmbeddedNavigator property and add two custom buttons (NextPage, PrevPage).
- Specify the Tag property for each button to distinguish custom buttons in code.
- Handle the GridControl.EmbeddedNavigator.ButtonClick event to increment/decrement the current page index, retrieve a new data source, and assign it to the GridControl.DataSource property.
private void EmbeddedNavigator_ButtonClick(object sender, NavigatorButtonClickEventArgs e) { if (e.Button.ButtonType != NavigatorButtonType.Custom) return; e.Handled = true; string tag = (string)e.Button.Tag; switch(tag) { case "NextPage": this.CurrentPageIndex = Math.Min(this.CurrentPageIndex + 1, this.MaxPageIndex); break; case "PrevPage": this.CurrentPageIndex = Math.Max(0, this.CurrentPageIndex - 1); break; } this.GridControl.DataSource = GetData(this.CurrentPageIndex); }Private Sub EmbeddedNavigator_ButtonClick(ByVal sender As Object, ByVal e As NavigatorButtonClickEventArgs) If e.Button.ButtonType <> NavigatorButtonType.Custom Then Return End If e.Handled = True Dim tag As String = CStr(e.Button.Tag) Select Case tag Case "NextPage" Me.CurrentPageIndex = Math.Min(Me.CurrentPageIndex + 1, Me.MaxPageIndex) Case "PrevPage" Me.CurrentPageIndex = Math.Max(0, Me.CurrentPageIndex - 1) End Select Me.GridControl.DataSource = GetData(Me.CurrentPageIndex) End Sub
