Need to know the sequence of events and any code or markup that might be causing it. Sadly, my powers of telepathy have waned so I can't see inside your head and I'm not very good at guessing.

Maybe you have AutoPostBack set to true on the textbox? Edit your question to add some markup/code so we can see an a small example of exactly what you're talking about.

Hope that the AutoPostback Property of text box is set "true".
It should be set to false.

Basically, you are doing a server-request using a POST when you need to use jQuery to do a client-side call. Here is an explanation of how to do this:

It's not clear that the OP even wants anything to update, but if they are I'd probably recommend to them that they just use an UpdatePanel (unless they were using MVC).

Well, I assumed that was the case because the "display name automatically displays", which seemed to indicate an update was happening/needed. An UpdatePanel would work, although I haven't used one in a while, since jQuery is so easy to use and is so powerful. The jQuery ajax is so great.

Please use AJAX. If you use AJAX (ScriptManager, UpdatePanel, Contenttemplate) the Page cannot refresh.

Place your Controls here within ContentTemplate

XML

<asp:ScriptManager ID="SavedScriptManager" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="savedUpdatePanel" runat="server">
    <ContentTemplate>

If I am not wrong after entering Username in your txtUsername Textbox, you want to display the name of that User, for that you had put the AutoPostback=true. which is right. but In this scenario you want the username without refreshing the page.

For avoiding page refresh use updatepanel
