Freeze Header and column for dynamically generated RadGrid

[Lydia]

Hi,
I have used a dynamically generated RadGrid for my application.
I would like to use the following functions:
1) Freeze header
2) Freeze columns
3) Resize one of the column
I know there's an article saying that resizing the column does not work with freezing header, so if we are to only use the freeze header and columns there are still some issues

here's the issues and settings I used:
- Freeze header only, no freezing columns
The grid has some alignment issue when scroll to the end, the header and content line is not aligned.
Pls see freezeheaderalignment.jpg
- Freeze header and column (must use layout = auto to make it show)
The last column disappear when using both freeze header and column and somehow the header height become very big and is it because of my fixed height, now i have 3 vertical scroll bars :(
Pls see freezeheaderncolumn.jpg

Also I noticed that I have to specify the width of each column otherwise the column will shrink, is there any auto-size property to automatically resize the column width as per content?

Here's my code:

RadGrid1 = new RadGrid();
RadGrid1.ID = "RadGrid1";
RadGrid1.Height = Unit.Pixel(535);

int intDefaultPercentage = 99;
bool isFixed = false;
if (!ConfigHelper.OPDashboardLayout.Equals(""))
{
    if (ConfigHelper.OPDashboardLayout.ToUpper().Equals("Fixed"))
        isFixed = true;
    RadGrid1.MasterTableView.TableLayout = (GridTableLayout)Enum.Parse(typeof(GridTableLayout), ConfigHelper.OPDashboardLayout);
}

RadGrid1.AutoGenerateColumns = false;
RadGrid1.ClientSettings.Scrolling.AllowScroll = true;
RadGrid1.ItemDataBound += new GridItemEventHandler(RadGrid1_ItemDataBound);
RadGrid1.PreRender += new EventHandler(RadGrid1_PreRender);
RadGrid1.ColumnCreated += new GridColumnCreatedEventHandler(RadGrid1_ColumnCreated);
RadGrid1.DetailTableDataBind += new GridDetailTableDataBindEventHandler(RadGrid1_DetailTableDataBind);
RadGrid1.NeedDataSource += new GridNeedDataSourceEventHandler(RadGrid1_NeedDataSource);
RadGrid1.ExcelExportCellFormatting += new OnExcelExportCellFormattingEventHandler(RadGrid1_ExcelExportCellFormatting);

RadGrid1.MasterTableView.Name = "Master";
RadGrid1.MasterTableView.DataKeyNames = new string[] {"KIID"};
RadGrid1.MasterTableView.GroupLoadMode = GridGroupLoadMode.Client;

RadGrid1.MasterTableView.Width = Unit.Percentage(intDefaultPercentage);
RadGrid1.MasterTableView.HeaderStyle.Wrap = true;
if (isFixed)
{
    RadGrid1.CssClass = "AutoShrink";
    RadGrid1.MasterTableView.CssClass = "AutoShrink";
}
//RadGrid1.MasterTableView.HierarchyLoadMode = GridChildLoadMode.Client;
