How to know when the order of the columns are changed in WinForms GridGroupingControl?

Change the column order
The order of particular column changes has been identified by using the TableDescriptor.Columns.Changing and TableDescriptor.Columns.Changed event.
C#
void Columns_Changed(object sender, Syncfusion.Collections.ListPropertyChangedEventArgs e)
{
if (e.Action == Syncfusion.Collections.ListPropertyChangedType.Move)
{
string columnName = this.gridGroupingControl1.TableDescriptor.Columns[e.Index].MappingName;
Console.WriteLine("Moved index", e.Index);
}
}
void Columns_Changing(object sender, Syncfusion.Collections.ListPropertyChangedEventArgs e)
{
if (e.Action == Syncfusion.Collections.ListPropertyChangedType.Move)
{
string columnName = this.gridGroupingControl1.TableDescriptor.Columns[e.Index].MappingName;
Console.WriteLine("Moving index", e.Index);
}
}
VB
Private Sub Columns_Changed(ByVal sender As Object, ByVal e As Syncfusion.Collections.ListPropertyChangedEventArgs)
If e.Action = Syncfusion.Collections.ListPropertyChangedType.Move Then
Dim columnName As String = Me.gridGroupingControl1.TableDescriptor.Columns(e.Index).MappingName
Console.WriteLine("Moved index", e.Index)
End If
End Sub
Private Sub Columns_Changing(ByVal sender As Object, ByVal e As Syncfusion.Collections.ListPropertyChangedEventArgs)
If e.Action = Syncfusion.Collections.ListPropertyChangedType.Move Then
Dim columnName As String = Me.gridGroupingControl1.TableDescriptor.Columns(e.Index).MappingName
Console.WriteLine("Moving index", e.Index)
End If
End Sub
