disable rows in datagrid silverlight 2.0

I have a datagrid and when user tries to edit a row then I want to have only that row editable and all other rows disabled. Is this possible ? I tried looking for datagrid.rows but there is none.开发者_开发问答

Please help

Thanks Sai

Take a look at the BeginEdit and EndEdit events here. If the default behavior isn't preventing you from editing the other rows while you are currently editing one you should be able to place some code in those events to disable selecting other rows while in edit mode.
