WPF DataGrid下滑动态加载数据

Posted 2021-03-05 lulus

效果如图：

重点是判断滑动到DataGrid底端（VerticalOffset等于ScrollableHeight），则继续加载数据

private void DataGrid_ScrollChanged(object sender, ScrollChangedEventArgs e)
{
    var scrollViewer = e.OriginalSource as ScrollViewer;
    if (e.VerticalOffset!=0 && e.VerticalOffset == scrollViewer.ScrollableHeight)
    {
        GenerateData();
    }
}
