WPF 分页控件
刚接触WPF，直接给公司做第一个WPF进销存小项目，分页实用四个button实现的，做完后突然感觉自己太傻了。。。为什么不用自定义用户控件。。于是就写了个简单分页控件
布局：
<UserControl x:Class="Com.FMS.View.UserControls.ZsmPager" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="50" d:DesignWidth="480" Loaded="UserControl_Loaded"> <Grid> <WrapPanel> <Button Name="btnFirstPage" Content="首页" Width="40" Margin="2" Click="btnFirstPage_Click"></Button> <Button Name="btnPageDown" Content="下一页" Width="50" Margin="2" Click="btnPageDown_Click"></Button> <Button Name="btnPageUp" Content="上一页" Width="50" Margin="2" Click="btnPageUp_Click"></Button> <Button Name="btnEndPage" Content="尾页" Width="40" Margin="2" Click="btnEndPage_Click"></Button> <TextBlock Name="txtPagerInfo" Text="当前第【{0}】页，共【{1}】页，共【{2}】条记录" Margin="5"></TextBlock> </WrapPanel> </Grid> </UserControl>
交互逻辑代码中主要就定义了一个委托事件，在页码改变的时候可以激发该事件

使用分页控件时的xaml
<my:ZsmPager x:Name="pagerUser" PagerIndexChanged="pagerUser_PagerIndexChanged" />
<Window>中添加xmlns:my="clr-namespace:命名空间"
在时实现控件PagerIndexChanged事件即可
/// <summary> /// 页码改变时激发该事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void pagerUser_PagerIndexChanged(object sender, EventArgs e) { //DataGrid数据绑定方法 DgUserDataBind(); }
样式简单，不漂亮，一般分页可以用，界面：
