WPF 自定义分页控件二

一:添加自定义分页控件,命名为KDataPagerTwo:

  1 public class KDataPagerTwo : Control, INotifyPropertyChanged
  2     {
  3         static KDataPagerTwo()
  4         {
  5             DefaultStyleKeyProperty.OverrideMetadata(typeof(KDataPagerTwo), new FrameworkPropertyMetadata(typeof(KDataPagerTwo)));

  8         public event PropertyChangedEventHandler PropertyChanged;
  9         protected void OnPropertyChanged(string propertyName)
 10         {
 11             PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
 12             if (propertyName == "PagerIndex")
 13             {
 14                 if (PagerIndex != 0)
 15                     ChosenNumber();
 16             }
 17             else if (propertyName == "PagerTotal" || propertyName == "PagerSize")
 18                 Refresh();

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

                            <TextBlock  x:Name="txt_One" Text="1" Style="{StaticResource Txt_Margin}"/>
                            <TextBlock  x:Name="txt_Two" Text="2" Style="{StaticResource Txt_Margin}"/>

                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>
View Code

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 - 1) * DataPager.PagerSize).Take(DataPager.PagerSize).ToList(); }
