代码写好之后在主页面调用该用户控件：
在主页面中<Window>中加入 xmlns:local="clr-namespace:用户控件命名空间"
然后只需在页面代码中嵌入 <local:用户控件名></local:用户控件名>即可使用
主页面后台调用代码：
privatevoid Form_Loaded(object sender, RoutedEventArgs e) { pager.PageSize =12; pager.PageCurrent =1; BindData(); pager.NMax = total; } string strWhere ="IsPass=1"; int total =0; DataSet ds; privatevoid BindData() { ds = OrderRecords.instance.GetList(pager.PageSize, pager.PageCurrent, strWhere, "Status asc,CurTime Desc", out total); gvOrderList.ItemsSource = ds.Tables[0].DefaultView; gvOrderList.CanUserAddRows =false; } privateint pager_EventPaging(Comm.EventPagingArg e) { int pagd = pager.PageCurrent; BindData(); return total; }
