延迟加载与WPF数据网格 [英] Lazy loading with wpf Data Grid

问题描述

起初我在填充数据网格100行，当用户滚动网格行，我想填充另一个100行。我使用WPF数据网格，我还没有发现数据网格，我能赶上来完成这项任务的任何事件。然后我用滚动浏览器控制，并试图赶上变化的事件，我知道，在结束我的滚动观众达到，然后我将加载在数据网格中的另一个行。

Initially I am populating 100 rows in Data grid, when user scroll the grid rows, I want to populate another 100 rows. I am using wpf data grid, I have not found any event of data grid that I can catch to accomplish this task. Then I have used scroll viewer control and try to catch change event where I know that my scroll viewer reach at end, then I will load another rows in data grid.

 <ScrollViewer Name="svDataGrid" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" ScrollChanged="ScrollViewer_ScrollChanged" >
            <DataGrid VerticalScrollBarVisibility="Disabled"   Background="Transparent" Visibility="Collapsed" Name="dgList" Grid.Row="1" IsSynchronizedWithCurrentItem="True"
                 AutoGenerateColumns="False" AlternatingRowBackground="Azure"
                 CanUserAddRows="False" CanUserDeleteRows="False"
                 CanUserSortColumns="True" CanUserReorderColumns="False"
                 CanUserResizeColumns="True" CanUserResizeRows="False" IsReadOnly="True" MouseDoubleClick="dgList_MouseDoubleClick"  PreviewKeyDown="dgList_PreviewKeyDown">
            </DataGrid>
        </ScrollViewer>
