Ajax can store the data that was loaded from database??

Thanks Suthish Nair. My question is i want to use ajax to contain the data and throw it into gridview .I mean i don't want to load all of element of the page.Like this: http://www.c-sharpcorner.com/1/224/Asp-Net-web-forms.aspx .I think "admin" use the gridview to display Articles's topic.When i press "2" number in it,I don't see it load page again.I want my website like that.Can you tell me the way or Article to do it?Thanks so much!!
