WPF自定义分页控件

做了许久伸手党,终于有机会贡献一波,搜索一下WPF分页控件,还是多,但是不太通用,主要就是样式问题,这个WPF很好解决,还有一个就是分页控件嘛,只关心几个数字的变动就行了,把页码改变事件暴露出来,数据的加载在这里就做就行,所以这个分页控件很简单...

好像也没啥讲的,直接上代码了

分页控件基本样式

<Style TargetType="{x:Type local:Pager}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:Pager}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<StackPanel Orientation="Horizontal"
VerticalAlignment="Center">
<StackPanel.Resources>
<Style TargetType="TextBlock">
<Setter Property="VerticalAlignment"
Value="Center"></Setter>
</Style>
</StackPanel.Resources>
<TextBlock Text="共"></TextBlock>
<TextBlock x:Name="PART_TotalCount">
</TextBlock>
<TextBlock Text="行,"></TextBlock>
<TextBlock Text="每页"></TextBlock>
<TextBlock x:Name="PART_PageSize">
</TextBlock>
<TextBlock Text="行,"></TextBlock>
<TextBlock Text="第">
</TextBlock>
<TextBlock x:Name="PART_PageIndex"></TextBlock>
<TextBlock Text="/"></TextBlock>
<TextBlock x:Name="PART_TotalPage"></TextBlock>
<TextBlock Text="页"></TextBlock>
<Button Margin="10,0,0,0"
Content="首页"
x:Name="PART_FirstPage"></Button>
<Button Margin="10,0,0,0"
Content="上一页"
x:Name="PART_PrePage"></Button>
<Button Margin="10,0,0,0"
Content="下一页"
x:Name="PART_NextPage"></Button>
<Button Margin="10,0,10,0"
Content="尾页"
x:Name="PART_LastPage"></Button>
<TextBox Width="50"
x:Name="PART_PageNum"></TextBox>
<Button Margin="10,0,0,0"
Content="转到"
x:Name="PART_PageGo"></Button>
</StackPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
