Hi Brijeshkhare, The unbound field’s value should be stored in a collection or in a datasource in the SaveValue event handler and the stored values should be retrieved in the QueryValue event handler. This was shown clearly in the sample (Checkbox_Unbound), in the previous forum thread. http://www.syncfusion.com/Support/forums/message.aspx?MessageID=43148 If you still get the issue please send a sample with the mentioned issue, so that we can get back soon with a solution.
