WPF DataGrid (SfDataGrid) allows you to perform the multiple sorting without pressing the Ctrl Key. You can achieve this by using the SortColumnsChanging event which will be raised while clicking on the column header. You should cancel the current sorting process and need to add the new sort column to SorColumnDescriptions using a Dispatcher. In WPF void SfdataGrid_SortColumnsChanging(object sender, GridSortColumnsChangingEventArgs e)
{
e.Cancel = true;
if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
{
this.SfdataGrid.Dispatcher.BeginInvoke(new Action(() =>
{
this.SfdataGrid.SortColumnDescriptions.Add(e.AddedItems[0]);
}), DispatcherPriority.ApplicationIdle);
}
else if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Replace)
{
this.SfdataGrid.Dispatcher.BeginInvoke(new Action(() =>
{
var sordesc = this.SfdataGrid.SortColumnDescriptions.FirstOrDefault(sd => sd.ColumnName == e.AddedItems[0].ColumnName);
this.SfdataGrid.SortColumnDescriptions.Remove(sordesc);
this.SfdataGrid.SortColumnDescriptions.Add(e.AddedItems[0]);
}), DispatcherPriority.ApplicationIdle);
}
}
In UWP private async void SfdataGrid_SortColumnsChanging(object sender, Syncfusion.UI.Xaml.Grid.GridSortColumnsChangingEventArgs e)
{
e.Cancel = true;
if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
{
await this.SfdataGrid.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
this.SfdataGrid.SortColumnDescriptions.Add(e.AddedItems[0]);
});
}
else if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Replace)
{
await this.SfdataGrid.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
var sordesc = this.SfdataGrid.SortColumnDescriptions.FirstOrDefault(sd => sd.ColumnName == e.AddedItems[0].ColumnName);
this.SfdataGrid.SortColumnDescriptions.Remove(sordesc);
this.SfdataGrid.SortColumnDescriptions.Add(e.AddedItems[0]);
});
}
}
