I have a .net 3.5 website in which I'm having several .aspx pages using a single master page. I'm facing an issue every time the pages are redirected.

I have a header in the master page where the title of website is displayed as image.

beneath that I have a content placeholder where all the content pages are displayed.

Now, I have a button in content page1 which redirects to content page2. When I click on the button it is redirecting to page 2 but the whole master page is posting back to the server. What I need is the content page only need to be posted back. posting back of master page should be avoided.

Please help me in this regard.
below is the markup of my master page.

Solution 1

If you mean you only want one part of the page updated (instead of the whole thing) you will need to use AJAX to provide partial page rendering.
This[^] is a microsoft tutorial on how to achieve it.
