Sorting using generic classes + c#

[abcurl]

Language - c# Database - sql server 2008 DataGridview It is regarding the sorting in the datagridview using generic classes as a datasource of datagridview I need suggestion for my implementation that whether my approach is right or wrong Following are the function.

private void datagridview1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
SetSorting(e.ColumnIndex);
}

private void SetSorting(int ColumnIndex)
{
if (ColumnIndex == -1) return;
IList data = null;
try
{
data = (IList<classInfo>)dgvUploadCharts.DataSource;
SortOrder order = SortGlyphDirectionPublication(ColumnIndex);
dgvUploadCharts.DataSource = SortingDataPublication(data, order, ColumnIndex);
dgvUploadCharts.Columns[ColumnIndex].HeaderCell.SortGlyphDirection = order;
}
catch (Exception ex)
{
throw ex;
}
finally
{
data = null;
}
}

private IList<classInfo> SortingDataPublication(IList<classInfo> Obj, SortOrder SortOrder, int ColumnIndex)
{
IEnumerable<classInfo> sortedEnum = null;
try
{
if (datagridview1.Columns[ColumnIndex].Name.ToString() == Enumeration.Enum1.ToString())
{
if (SortOrder == SortOrder.Ascending || SortOrder == SortOrder.None)
sortedEnum = Obj.OrderBy(f => f.Enum1);
if (SortOrder == SortOrder.Descending)
sortedEnum = Obj.OrderByDescending(f => f.Enum1);
return sortedEnum.ToList();
}
}
}

private SortOrder SortGlyphDirectionPublication(int ColumnIndex)
{
SortOrder order = datagridview1.Columns[ColumnIndex].HeaderCell.SortGlyphDirection;
if (order == SortOrder.None)
return SortOrder.Ascending;
if (order == SortOrder.Ascending)
return SortOrder.Descending;
if (order == SortOrder.Descending)
return SortOrder.Ascending;
return SortOrder.Ascending;
}

The easiest way to determine whether your implementation is right, is by testing it. Well, does it work? Looks readable enough, why are you doubting?
