Sorting Issue

[Itl]

Hi all,

I have very strange issue, can some one enlighten me what can be the reason?
Here is brief description of what going on:
  1. RadGrid binded to List<WorkstationInfo> where Workstation is simple class
  2. binding happen in NeedDataSource event
  3. In SortCommand, I perform custom sorting.

 var sortExpr = new GridSortExpression();
                switch (e.OldSortOrder)
                {
                    case GridSortOrder.None:
                        sortExpr.FieldName = e.SortExpression;
                        sortExpr.SortOrder = GridSortOrder.Descending;


                        e.Item.OwnerTableView.SortExpressions.AddSortExpression( sortExpr );
                        break;
                    case GridSortOrder.Ascending:
                        sortExpr.FieldName = e.SortExpression;
                        sortExpr.SortOrder = gridWorkstationStatus.MasterTableView.AllowNaturalSort ? GridSortOrder.None : GridSortOrder.Descending;
                        e.Item.OwnerTableView.SortExpressions.AddSortExpression( sortExpr );
                        break;
                    case GridSortOrder.Descending:
                        sortExpr.FieldName = e.SortExpression;
                        sortExpr.SortOrder = GridSortOrder.Ascending;


                        e.Item.OwnerTableView.SortExpressions.AddSortExpression( sortExpr );
                        break;
                }


                e.Canceled = true;
                gridWorkstationStatus.Rebind();

All works fine first to clicks on any columns, then it stop working. To continue sort, the mouse should be clicked on logo or on already existed sort image button, but when other column is clicked, nothing happen - the post-back event not fired and no events called on server.

It's work fine on chrome, but on IE 8,9 it is have this issue.

Here is aspx page code:

Hello George,

It would be hard to guess the problem by examining your code. This is why I created a simple demo based on your code-snippet. Please test it locally and let me know whether it works as expected.

Hi,

I still checking this issue, but it look like I understand the reason. When using IE 9 while IE running using Document Mode: IE8 standards this behaviour occurs, but when it setted up correctly, it works fine.

Thanks

Hello George,

Still, this seems strange to me. I would gladly help you sort that issue out if you can isolate it in a simple, runnable project.
