Since the columns are "User Defined" this is how I do this..

Note that we use an Inherited class of the RadGridView

1. clear the columns, group, and SortDescription
            this.Columns.Clear();
            this.Items.GroupDescriptions.Clear();
            this.Items.SortDescriptions.Clear();

2.I Iterate throw the columns to add.. (see code below...)

3.I Set the items source that is a ICollectionView (our implementation ...)

var itemColumn = pair.ColumnDefinition;
 
string path = DataBindingHelper.GetBindingPath(itemColumn.ColumnName, collectionType);  // ex: CustomerId
 
bool isImage = (pair.ColumnDefinition.BusinessEntityInfo == null ?
                                itemColumn.ColumnType == typeof(byte[]) :
                                pair.ColumnDefinition.BusinessEntityInfo.DynamicControlCaptureMode == DynamicControlCaptureMode.Image);
bool isNum = false;
GridViewBoundColumnBase col;
if (isImage)
{
    col = new Telerik.Windows.Controls.GridViewImageColumn();
    col.IsGroupable = false;
    col.IsSortable = false;
    col.IsFilterable = false;
}
else
{
    isNum = TypeUtility.IsNumericType(itemColumn.ColumnType);
    col = new GridViewDataColumn();
    col.IsGroupable = true;
    col.IsSortable = true;
    col.IsFilterable = true;
    col.ShowFieldFilters = false;
 
    // For traduction..
    var fil = new MaxFilteringControl(itemColumn, pair.Process == null ? ApplicationBase.CurrentUser : pair.Process.User);
    col.FilteringControl = fil;
 
}
// For design perpose...
MaxDataGridHelper.SetColumnDefinition(col, itemColumn);
col.DataMemberBinding = new Binding(path) { Mode = BindingMode.OneWay };
col.Header = itemColumn.Label;
 
if (itemColumn.Width > 0)
    col.Width = itemColumn.Width;
 
col.IsVisible = itemColumn.ShowInList;
var coldef = pair.ColumnDefinition;

/... some code removed for clarity.../
 
if (!isImage && col.IsVisible && itemColumn.ColumnType != null && itemColumn.ColumnType.IsEnum)
{
    col.DataMemberBinding.Converter = MaxDataGridHelper.ObjectCaptionConverter;
    col.DataMemberBinding.ConverterParameter = itemColumn.ColumnType;
}
 
else if (!isImage && col.IsVisible && (!string.IsNullOrEmpty(itemColumn.DisplayFormat) || isNum || itemColumn.ColumnType == typeof(DateTime)))
{
    if (isNum)
        col.TextAlignment = TextAlignment.Right;
 
    if (!string.IsNullOrEmpty(itemColumn.DisplayFormat))
        col.DataFormatString = itemColumn.DisplayFormat;
 
    else if (itemColumn.ColumnType == typeof(DateTime))
        col.DataFormatString = "d";
}

// "this" is the inherited class definition
this.Columns.Add(col);

yes. the sort description is added

see screen shot..

I did try a test, create my own column, override your CanSort() to see the real value (see sort1.png)
Also attach to the "Sorted Event" to try "grid.Items.Refresh()..." and check properties values (see sort2.png)

Note that the same code work with the version 2010.3.1110.35 but not with the lastest (2011.1.0315.40) neither the previous..

I did try several thing, using or not the dispatcher, setting back the items source..
...
Also note that everything is done by code (not xaml) since this is user defined...
Also, with this version, if I create the column and set the items source (it display the columns ok) but if I do the Itemssource and columns after, wrong display (see columns1 and 2.png) I Can send you a video (more explicite..)

Thank
