如何在数据网格中禁用组列描述字段的排序？

Question

我的xaml代码中有一个数据网格。我在视图模型中通过处理排序列改变事件来应用排序。还有一个单独的组列描述字段。

当我用一列对网格进行排序时，无论我选择什么顺序，调试器都会显示正确的结果，但当它出现在屏幕上时，它又被分组的列排序了。

这是我的xaml代码。

这是我的视图模型代码，其中有Sort Columns Changed事件。

public DelegateCommand<GridSortColumnsChangedEventArgs> SortingChangedOnGrid { get; }
SortingChangedOnGrid = new DelegateCommand<GridSortColumnsChangedEventArgs(SortingOnSFDataGridChanged);

private void SortingOnSFDataGridChanged(GridSortColumnsChangedEventArgs sortingdata)
    {
        try
        {
            var newSearchtotalFullList = new List<UndeliveredReportModel>();
            var columnNameSelected = sortingdata.AddedItems.FirstOrDefault().ColumnName;

            List<UndeliveredReportModel> totalDataAsPerFilterr = new List<UndeliveredReportModel>();
            switch (columnNameSelected)
            {
                case "Recipient":
                    if (sortingdata.AddedItems.FirstOrDefault().SortDirection == Syncfusion.Data.ListSortDirection.Ascending)

我正在使用Syncfusion UWP工具来实现这个功能，因为它符合我们的要求。

先谢谢你。

你的要求可以通过在SfDataGrid的GroupColumnDescriptions中设置SortGroupRecords值为False来实现。请参考下面的代码片段，供您参考。

<syncfusion:SfDataGrid.GroupColumnDescriptions>
   <syncfusion:GroupColumnDescription ColumnName="OrderID" SortGroupRecords="False" /> 
</syncfusion:SfDataGrid.GroupColumnDescriptions>
