Sorting is an important requirement when it comes to listing data alphabetically and arranging data in ascending or descending order. C1FlexSheet uses AllowSorting property to sort data in a worksheet.

In XAML

You can easily sort data using AllowSorting property in XAML View. The following code illustrates the use of AllowSorting property:

<c1:C1FlexSheet x:Name="flexsheet" AllowDragging="Columns" AllowSorting="True" Margin="0,25,0,0"/>

In Code

The following code illustrates the use of AllowSorting property in Code view:

flexsheet.AllowSorting = True

flexsheet.AllowSorting = true;

The C1FlexSheet control also provides range-based unbound sorting. Sorting in FlexSheet can be done by using SortDialog class. The following lines of code show the unbound sorting in C1FlexSheet control:

If flexsheet.Columns.Count > 0 Then
    Dim sortDialog = New SortDialog(flexsheet)
    sortDialog.Show()
End If

if (flexsheet.Columns.Count > 0)
{
    var sortDialog = new SortDialog(flexsheet);
    sortDialog.Show();
} 

The Sort dialog box provides options of adding, deleting, and copying levels. You can specify columns and their respective orders (ascending or descending) for sorting data in these levels.
