update query from page_load executes again and again when button from update panel is cliked
<p>I have one Update Query on <code>page_load()</code>. I have a button on page.
I want to execute that query only once, but when I click on button, the page loads again.</p>

<p>I therefore put that button in update panel.
Now when I click on the button, the page doesn't seem to be reloading but that update query is executing.</p>

<p>what may be the problem?</p>
