WPF 自定义分页控件二

一:添加自定义分页控件,命名为KDataPagerTwo:

 public class KDataPagerTwo : Control, INotifyPropertyChanged
{
static KDataPagerTwo()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(KDataPagerTwo), new FrameworkPropertyMetadata(typeof(KDataPagerTwo)));
} public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string propertyName)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
if (propertyName == "PagerIndex")
{
if (PagerIndex != )
ChosenNumber();
}
else if (propertyName == "PagerTotal" || propertyName == "PagerSize")
Refresh();
} #region 变量定义

public TextBlock txt_One;
public TextBlock txt_Two;
public TextBlock txt_Three;

} //使用一个依赖属性作为PagerCount的后备存储器。这支持动画、样式、绑定等。

二:定义资源字典文件,命名为DataPagerTwo:

说明:local:KImgButton,这个也是一个自定义控件,可以改成Button控件也没有问题

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:BaseControl"
>
<Style TargetType="Image" x:Key="Img_Size" >
<Setter Property="Width" Value="14"/>
<Setter Property="Height" Value="14"/>
</Style>
<Style TargetType="TextBlock" x:Key="Txt_Root">
<Setter Property="FontFamily" Value="新宋体"></Setter>
<Setter Property="FontSize" Value="14"></Setter>
<Setter Property="VerticalAlignment" Value="Center"></Setter>
<Setter Property="Foreground" Value="#193A57"></Setter>
</Style>
<Style TargetType="TextBlock" x:Key="Txt_Side" BasedOn="{StaticResource Txt_Root}">
<Setter Property="Foreground" Value="#193A57"></Setter>
<Setter Property="HorizontalAlignment" Value="Center"></Setter>
</Style>
<Style TargetType="TextBlock" x:Key="Txt_Margin" BasedOn="{StaticResource Txt_Root}">
<Setter Property="Margin" Value="4"/>
<Setter Property="Cursor" Value="Hand"></Setter>
</Style>
<Style TargetType="local:KImgButton">
<Setter Property="IsEnabled" Value="True"></Setter>
<Setter Property="CornerRadius" Value="2"></Setter>
<Setter Property="FIconSize" Value="0"></Setter>
</Style>
<Style TargetType="{x:Type local:KDataPagerTwo}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:KDataPagerTwo}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Orientation="Horizontal" Margin="10,0">
<TextBlock Style="{StaticResource Txt_Side}" Text="共"></TextBlock>
<TextBlock Style="{StaticResource Txt_Side}" Text="0" Margin="5,0" x:Name="txt_Total"></TextBlock>
<TextBlock Style="{StaticResource Txt_Side}" Text="条数据。"></TextBlock>
</StackPanel>
<StackPanel Orientation="Horizontal" Grid.Column="1" x:Name="Stack_Control" HorizontalAlignment="Right" Margin="10,0">
<Image x:Name="Img_HomePage" Source="/BaseControl;component/Images/DataPagerImages/First.png" Margin="5,0" Style="{ StaticResource Img_Size}" Cursor="Hand"/>
<Image x:Name="Img_PreviousPage" Source="/BaseControl;component/Images/DataPagerImages/prev.png" Style="{ StaticResource Img_Size}" Cursor="Hand"/> <TextBlock x:Name="txt_One" Text="1" Style="{StaticResource Txt_Margin}"/>
<TextBlock x:Name="txt_Two" Text="2" Style="{StaticResource Txt_Margin}"/>
<TextBlock x:Name="txt_Three" Text="3" Style="{StaticResource Txt_Margin}"/>
<TextBlock x:Name="txt_Four" Text="4" Style="{StaticResource Txt_Margin}"/>
<TextBlock x:Name="txt_Five" Text="●●●" Style="{StaticResource Txt_Margin}"/>
<TextBlock x:Name="txt_Six" Text="10" Style="{StaticResource Txt_Margin}"/> <Image x:Name="Img_NextPage" Source="/BaseControl;component/Images/DataPagerImages/Next.png" Style="{ StaticResource Img_Size}" Cursor="Hand"/>
<Image x:Name="Img_TailPage" Source="/BaseControl;component/Images/DataPagerImages/Last.png" Margin="5,0,20,0" Style="{ StaticResource Img_Size}" Cursor="Hand"/> <TextBlock Text="到第" Style="{StaticResource Txt_Root}" Margin="-5,5,5,5"></TextBlock> <Border Margin="0,5,5,5" Background="#4081D1" BorderBrush="#4081D1" Width="19" Height="19">
<TextBox x:Name="txt_Jump" FontFamily="微软雅黑" VerticalContentAlignment="Center" VerticalAlignment="Center" HorizontalContentAlignment="Center" HorizontalAlignment="Center" FontSize="12" Width="17" Height="17" BorderThickness="0"/>
</Border> <TextBlock Text="页" Style="{StaticResource Txt_Root}" Margin="0,0,20,0"></TextBlock> <local:KImgButton x:Name="btn_Ok" FontFamily="新宋体" FontSize="14" Content="跳转" Height="20" Width="50" Background="#4081D1" Margin="-10,0,0,0"/>
</StackPanel>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>

三:在Generic中引用资源字典文件:

    <ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/BaseControl;component/Themes/DataPagerTwo.xaml" />
</ResourceDictionary.MergedDictionaries>

四:将Generic中下面代码删除:

<Style TargetType="{x:Type local:KDataPagerTwo}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:KDataPagerTwo}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

五:现在就可以用了,用法:

先引用:WPF 自定义分页控件二

再添加:WPF 自定义分页控件二

六:后台PropertyChanged事件代码(当前页数发生变化,就可以根据DataPager.PagerIndex传入分页方法):

        /// <summary>
/// 当某一属性值发生改变事件
/// </summary>
private void DataPager_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
//分页方法(根据需要可以写成其他分页方法)
       //DataPager.PagerIndex--当前页,DataPager.PagerSize--每页记录数
datagrid1.ItemsSource = TL.ToList().Skip((DataPager.PagerIndex - ) * DataPager.PagerSize).Take(DataPager.PagerSize).ToList();
}
