ASPxGridView - NewValues and OldValues are equal when the editor is disabled on the server

My problem is the same as this Q328185!
I wanted to add some information, hoping to help resolve.
In my case, two columns run regularly, when I change the value NewValues and OldValues are different and show the right values, but for one column NewValues and OldValues are always equals. For this column, even when I change the value in the NewValues I always see the old value.
I also tried to set the filedName property of the bad column on one of the other two, but the result is always the same.

Hello Francesco:
I am afraid we can't reproduce the issue described in Q328185.
Could you please illustrate it with a sample or modify the project attached to that report?
Thanks
Kate.

Hello Kate,
I identified the cause of my problem.
I'm using the event CellEditorInitialize to disable the edit on some rows, this is my code:
protected void grid_CellEditorInitialize(object sender, ASPxGridViewEditorEventArgs e)
{
    if (e.Column.Name == "value")
      if(gridTransactions.GetDataRow(e.VisibleIndex)["eventId"].ToString()=="999")
        e.Editor.Enabled = false;
}
With this code in the RowUpdating event for the column "value" NewValues and OldValues always equals.
This only after you have upgraded to version v2011 vol 1.4.
Regards
Francesco

Hello Francesco:
Please cast an editor to the corresponding type (ASPxTextBox, ASPxComboBox and so on) and use the ClientEnabled property instead of Enabled. For example:

C#
protected void grid_CellEditorInitialize(object sender, ASPxGridViewEditorEventArgs e)  
{  
    if (e.Column.Name == "value")  
      if(gridTransactions.GetDataRow(e.VisibleIndex)["eventId"].ToString()=="999")  
        (e.Editor as ASPxTextBox).ClientEnabled = false;  
}

Does it help?
Thanks
Kate.
