Try to Serialize the Object.[[^]]

I have sql query and I want to save every running the row that selected from each table. I found solution for that :D. I mark the dmbl as serializable with <Database... Serialization="Unidirectional"> and than use NetDataContractSerializer object to serialize\deserialize. Now, I have another problem, I want to save also the search criterions, every search I save the controls with the search criterions in hashtable, and I want to save it also at xml but the controls are not serializable(I use wpf and telerik controls). Is thare any way to do it? Thanks again.
