    QTitle.Text = "MyUserName";

}

You can store it in the class then access it with code behinds like <%= myVar %> in your front end.

if you want to modify the values of divs on the front end then you need to use asp tags like

<asp:label runat="server" name="Qtitle"> </asp:label>

First of all you really need to think about moving to newer versions of XHTML/HTML! (I suggest you that because of your markup code).

In the other hand, in order to get your "QTitle" text set from server, you'll need to set "runat" attribute to "server" in your input, but, if you're using standard (X)HTML elements, you won't have such property "Text".

I suggest you to use a server control like TextBox which has the whole "Text" property:

<asp:TextBox ID="QTitle" runat="server" CssClass="Violet" />

Some server code-behind:

QTitle.Text = "Hello world";

Another suggestion is you won't be setting any property after PreRender ASP.NET Page life-cycle event.

Is the mark-up at the top of your question the resulting html or the source code for the form you are working with? If this is in-fact your asp.net form, try replacing the input tag with the following...

<asp:TextBox id="QTitle" runat="server" />

If the form is properly linked to the C# codebehind file you are using, QTitle.Text should now be accessible.
