On button click load UserControl without refreshing whole page
<p>Explaining my problem: </p>

<p>In my ASP.NET solution i have 2 buttons:</p>

<p>Button 1 and Button 2 </p>

<p>I have two UserControls with totally different content</p>

<p>OnClick of each of those buttons i want to load different UserControl into ContentPlaceHolder, but without reload whole page. So actually it have to work like Ajax TabContainer (but without loading all tabs at once). </p>

<p>I have tried to solve this problem with Ajax TabContainers, but loading times was just awful.</p>

<p>Anyone had same problem? How do u solve this one guys? </p>
