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();
         }

                            <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：

再添加：

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();
        }
