Dear All,
i followed the link http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/automatic-crud-operations/defaultcs.aspx and was able to see the data data in the RadGrid. But i was unable to edit or delete and when i tried to insert a row i wasn't able to see the text box where you can enter the data. i can only see a tick and a cross button . when i click on the tick button an empty row will be added to the table.

This behavior is pretty strange and based on the provided information will be hard to pinpoint the reason for that behavior. Nevertheless I noticed that you have AJAX enabled on your page. Could you please disable the AJAX and let me know whether a server side exception is not thrown?
