I have managed to update the records in the database using the following codes however after the click event of the update button regardless of what it does ,simply doesn't get refresh.Radgrid gets refreshed with the updated data if I click on end editing which is not what I want.
And whilst i try to insert records , it simply doesn't take,instead it scares me with an error message .i will very thankful to you if u can help me out.I use a liecensed version but can't open a ticket yet .

Can you please remove the AllowAutomaticUpdates="true", and let me know how it goes. If you are handling the inserts/updates manually, the automatic operations for the control should be disabled.
