I have designed a masterpage in asp.net.
There is a dropdown list in my asp.net form which select that masterpage.
But each time when I select an item from the dropdownlist the entire page gets refreshed. I want a javasript code to block the refresh of dropdownlist item selection and as well as how to intregrate the code in my form.

I am a beginner. Please somebody help me.
