WPF最简单的分页控件

背景：最近在写项目的时候需要写一个简单的分页功能，因项目需要，没有改为MVVM模式，只需要在后台实现

1、呈现效果如下：

接下来就来上代码，看看怎么实现的

1、界面代码

                 <StackPanel Orientation="Horizontal"
                             HorizontalAlignment="Right">
                     <TextBlock TextWrapping="WrapWithOverflow"
                                HorizontalAlignment="Right"
                                Margin="5,0,5,0"
                                VerticalAlignment="Center"
                                Text="{Binding OrderCount}">
                     </TextBlock>
                     <Button ToolTip="上一页"
                             Width=""
                             Height=""
                             FontSize=""
                             Name="BtnPreviousPage"
                             Background="#FFFFFF"
                             Click="BtnPreviousPage_Click"
                             Margin="5,0,5,0">
                     </Button>
                     <Border BorderBrush="#009639"
                             BorderThickness=""
                             Width=""
                             Height=""
                             Margin="5,0,5,0">
                         <TextBlock TextWrapping="WrapWithOverflow"
                                    Text="{Binding CurrentPage}"
                                    Foreground="#009639"
                                    VerticalAlignment="Center"
                                    HorizontalAlignment="Center"/>
                     </Border>
                     <Button ToolTip="下一页"
                             Width=""
                             Height=""
                             FontSize=""
                             Background="#FFFFFF"
                             Name="BtnNextPage"
                             Click="BtnNextPage_Click"
                             Margin="5,0,5,0">
                     </Button>
                 </StackPanel>

界面代码

2、后台代码

         private string _amountMoney;

         private string _orderCount;

         private int _currentPage = ;

         private int _pageSize = ;

         /// <summary>
         /// 未上传订单总数
         /// </summary>
         private int _count;

         List<OrderJMSStatus> mList = new List<OrderJMSStatus>();

         public int CurrentPage
         {
             get { return _currentPage; }
             set
             {
                 if (_currentPage != value)
                 {
                     _currentPage = value;
                     RaisePropertyChanged("CurrentPage");
                 }
             }
         }

         public string OrderCount
         {
             get { return _orderCount; }
             set
             {
                 if (_orderCount != value)
                 {
                     _orderCount = value;
                     RaisePropertyChanged("OrderCount");
                 }
             }
         }

         public string AmountMoney
         {
             get { return _amountMoney; }
             set
             {
                 if (_amountMoney != value)
                 {
                     _amountMoney = value;
                     RaisePropertyChanged("AmountMoney");
                 }
             }
         }
        public event PropertyChangedEventHandler PropertyChanged;
         public void RaisePropertyChanged(string propertyName)
         {
             if (PropertyChanged != null)
                 PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
         }
         private int GetPageNumber(int count, int rowNumber)
         {
             if (count ==  || rowNumber == )
             {
                 return ;
             }
             int pageNumber = count / rowNumber;
             if (count % rowNumber != )
             {
                 pageNumber++;
             }
             return pageNumber;
         }

         private void BtnNextPage_Click(object sender, RoutedEventArgs e)
         {

             if (CurrentPage == GetPageNumber(_count, _pageSize))
             {
                 return;
             }

             List<OrderJMSStatus> result = mList.Skip(CurrentPage * _pageSize).Take(_pageSize).ToList();

             MessageList.Clear();
             MessageList = result;
             CurrentPage++;
         }

         private void BtnPreviousPage_Click(object sender, RoutedEventArgs e)
         {
             if (CurrentPage == )
             {
                 return;
             }

             List<OrderJMSStatus> result = new List<OrderJMSStatus>();

             if (CurrentPage == )
             {
                 result = mList.Take(_pageSize).ToList();
             }
             else
             {
                 result = mList.Skip((CurrentPage - ) * _pageSize).Take(_pageSize).ToList();
             }

             MessageList.Clear();
             MessageList = result;

             CurrentPage--;
         }

后台代码

实现过程基本上就是这样，希望能对你有所帮助
