WPF分页控件

最近要写个程序要用到分页控件，找到了很多好高级的，代码拿到了也看不懂。最后找到了一个能看懂的，完善了一下。

调用页面代码
xmlns:MyNamespace="clr-namespace:WpfCustomControlLibrary;assembly=WpfCustomControlLibrary"
//先引用自定义控件项目
MyNamespace:PagerControl HorizontalAlignment="Right" x:Name="pager" Grid.Row="3">
MyNamespace:PagerControl>
调用页面后台代码
public MainForm()
{
InitializeComponent();
pager.PageSize = 30;//设置每页数据量
pager.Logs = AllLog;//设置数据源IList格式，DataTable尝试传DataTable.Rows,不行就把控件后台代码重写了吧
pager.dg = datagrid;//装载数据的DataGrid控件
}
有些问题没有处理，不知为何控件IsEnable属性设置为空时，无法改变按钮的颜色。
跳转没做，因为我的项目总共的数据量也不大，需要的自己加上，只要把Index传给 AddAndRemove(int Index,object sender, RoutedEventArgs e) 这个方法就好了，
因为这个方法我是嵌在事件里用的，实际只传Index就可以，其余两个属性照搬事件的属性就好。
