Hi Hilary,
Thanks for your advice. With you advice I was able to achieve the results but with not complete success. Let me give you a brief introduction about my SQL server table and form.
Table:
Problem1: On the selection of date previous date selection is not getting cleared. Shown in Image below
I have applied this rule to clear my dropdown list box.
Problem2: While clicking on View Report, I get this pop up which is confusing for the users.
Problem 3: While closing the form which is deployed on SharePoint I get this message to save the .xml form. I don't want this pop up, since this is a SQL server based form and I am never going to save this form.

Any suggestion would be appreciated.
Thanks & Regards,
