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
