How to sort checkbox items in the FilterPopup based on the DisplayValue?
By default, in WPF DataGrid(SfDataGrid) GridComboBoxColumn the checkbox elements in the FilterPopup will be sorted based on the edit value (SelectedValuePath) of the column. You can sort the checkbox elements in the FilterPopup based on the display value (DisplayMemberPath) of the column by using a custom sort comparer for the filter elements in the SfDataGrid.FilterItemsPopulated event.
private void DataGrid_FilterItemsPopulated(object sender, Syncfusion.UI.Xaml.Grid.GridFilterItemsPopulatedEventArgs e)
{
(e.ItemsSource as List<FilterElement>).Sort(new FilterElementComparer());
}
public class FilterElementComparer : IComparer<FilterElement>
{
public int Compare(FilterElement x, FilterElement y)
{
if (x == null)
{
if (y == null)
{
// If x is null and y is null, they're
// equal.
return 0;
}
else
{
// If x is null and y is not null, y
// is greater.
return -1;
}
}
else
{
// If x is not null...
//
if (y == null)
// ...and y is null, x is greater.
{
return 1;
}
else
{
return x.DisplayText.CompareTo(y.DisplayText);
}
}
}
}
