save and submit buttons

[Bhasker Pinninti]

Hi I am having a web application with some textboxes, dropdownlists and two buttons. one button is save and one button is submit. i need the following functionality for save button: suppose if you fill the fields with partially info(assume you don't have some info in that specific time) and click the save button. The save button will save the data but not update the database. In next time login, the data which you filled previously, should display the corresponding fields. Need answer or URL if you know...... Thanks, Bhasker P
