这篇博客主要介绍了如何在XAML界面中实现页码按钮的点击检测，包括XAML的界面代码和XAML.CS部分的逻辑处理。在XAML中，页码通过Label展示，并在XAML.CS中引入代码进行事件处理。示例中提供了3页的页码切换，若需扩展更多页面，只需调整if语句即可。

总结

一、界面XAML代码

1、这里关于跳转的页码显示使用Lable文本

代码如下（示例）：

<Button x:Name="shangyiye" Content="上一页" Foreground="Black" Grid.Column="1" Grid.Row="3"  VerticalContentAlignment="Center" FontSize="30" Background="{x:Null}" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="0,0,200,0" Click="Shangyiye_Click"/>
<Label x:Name="yema" Content="1" FontSize="30" Foreground="Black" Grid.Column="1" Grid.Row="3" HorizontalAlignment="Right" VerticalContentAlignment="Center" VerticalAlignment="Center" Margin="0,0,140,0" />
<Button x:Name="xiayiye" Content="下一页" Foreground="Black" Grid.Column="1" Grid.Row="3"  VerticalContentAlignment="Center" FontSize="30" Background="{x:Null}" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="0,0,20,0" Click="Xiayiye_Click"/>

二、关于XAML.CS部分代码

1.引入代码

1、本文提供的页码数仅为3页，如果需要多页修改if语句就行
代码如下（示例）：

int a1, a2;
int clickTimes1,clickTimes2,clickTimes3;
private void Shangyiye_Click(object sender, RoutedEventArgs e)
        {

            object tag = this.xiayiye.Tag;
            if (tag == null)
            {
                clickTimes1 = 1;
            }
            else
            {
                clickTimes1 = Convert.ToInt32(tag);
            }
            this.xiayiye.Tag = --clickTimes1;
            a1 = clickTimes1;                    
            if (a1 <= 1)
            {
                yema.Content = 1;
                this.xiayiye.Tag = 1;
            }
            else
            {
                yema.Content = a1;
            }
            if (a1 == 1)
            {
                DXLB1.Visibility = Visibility;
                DXLBtwo.Visibility = Visibility.Hidden;
                DXLB1three.Visibility = Visibility.Hidden;
            }
            if (a1 == 2)
            {
                DXLB1.Visibility = Visibility.Hidden;
                DXLBtwo.Visibility = Visibility;
                DXLB1three.Visibility = Visibility.Hidden;
            }
            if (a1 == 3)
            {
                DXLB1.Visibility = Visibility.Hidden;
                DXLBtwo.Visibility = Visibility.Hidden;
                DXLB1three.Visibility = Visibility;
            }
        }
        
        private void Xiayiye_Click(object sender, RoutedEventArgs e)
        {
            object tag = this.xiayiye.Tag;
            if (tag == null)
            {
                clickTimes2 = 1;
            }
            else
            {
                clickTimes2 = Convert.ToInt32(tag);
            }
            this.xiayiye.Tag = ++clickTimes2;
            a2 = clickTimes2;
            if (a2 >= 3)
            {
                yema.Content = 3;
                this.xiayiye.Tag = 3;
            }
            else
            {
                yema.Content = a2;
            }
            if (a2 == 1)
            {
                DXLB1.Visibility = Visibility;
                DXLBtwo.Visibility = Visibility.Hidden;
                DXLB1three.Visibility = Visibility.Hidden;
            }
            if (a2 == 2)
            {
                DXLB1.Visibility = Visibility.Hidden;
                DXLBtwo.Visibility = Visibility;
                DXLB1three.Visibility = Visibility.Hidden;
            }
            if (a2 == 3)
            {
                DXLB1.Visibility = Visibility.Hidden;
                DXLBtwo.Visibility = Visibility.Hidden;
                DXLB1three.Visibility = Visibility;
            }
        }
