DevExpress.XtraEditors.DataNavigator用法

作者：jiankunking ​​​​

1、DevExpress.XtraEditors.DataNavigator刚拖到winform窗体上的样子：

设置DataNavigator控件属性Dock=Bottom;TextLocation=End;TextStringFormat=第 {0}页 ,共 {1}页;

如果想显示ToolTip，需把ShowToolTips设置为True. 设置Button的Hint为自己想要显示的内容即可。

比如：

在运行时会有下面效果：

上图中的首页、前一页、后一页、尾页的图片是自定义的，那么怎么使用自定义图片呢？

拖拽一个imageList控件，然后在imageList中选择要使用的自定义图片

然后在Buttons选项卡下将ImageList设置为刚才选择过图片的imageList1控件，然后在DataNavigator控件 buttons下选择荼盘即可，比如下图的First

按钮事件处理：

private void dataNavigator1_ButtonClick(object sender, DevExpress.XtraEditors.NavigatorButtonClickEventArgs e)
        {         
                //下一页
                if ((e.Button).ButtonType == DevExpress.XtraEditors.NavigatorButtonType.NextPage)
                {
                }
                //上一页
                if ((e.Button).ButtonType == DevExpress.XtraEditors.NavigatorButtonType.PrevPage)
                {
                }
                //首页
                if ((e.Button).ButtonType == DevExpress.XtraEditors.NavigatorButtonType.First)
                {   
                }
                //尾页
                if ((e.Button).ButtonType == DevExpress.XtraEditors.NavigatorButtonType.Last)
                {
                }
        }

dev官方文档：

DataNavigator Class

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

Namespace: ​​DevExpress.XtraEditors​​

Assembly:

DevExpress.XtraEditors.v14.2.dll

 Syntax

public class DataNavigator : NavigatorBase, IDataNavigatorOwner

C#

VB

 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.

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 ​​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 ​​DataSource​​​ and ​​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.
