I asked a question before about a JavaScript code you can see it here : How can I scroll down to a multiline TextBox's bottom line, Javascript's scrollIntoView is not working for this. Well, it was solved and the accepted answer was working.
Afterwards I had to move the code part you can see in that question to a User Control which finally looked like this :
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="LiveChatPart.ascx.cs" Inherits="BeyzamComArayuz.LiveChatUserControl.LiveChatPart" %>
<%@ Register src="/LiveChatUserControl/GenelOdaFlashPart.ascx" tagname="GenelOdaFlash" tagprefix="gOF" %>
<script language="javascript" type="text/javascript">
function buttonClicked() {
// var el = document.getElementById("TxtBxOdaMesajlari");
var textBox = $get("TxtBxOdaMesajlari");
textBox.scrollTop = textBox.scrollHeight;
// $get("TxtBxOdaMesajlari").scrollIntoView("false");
}

EDIT: I tried to debug the webpage with IE9's built in debugger and put a breakpoint in the buttonClicked() function but it was never hit.Then I used the OnClientClick event of the button and added buttonClicked function to it it works for each click but then textbox just jumps back to where it was before buttonClicked() function.

Reset to default 3The issue is that ids for controls on a user control are somewhat mangled in that they include the user control's id plus the actual control's id. So your control's id probably looks something like: ucLiveChatPart_TxtBxOdaMesajlari.
The easy way to handle this is to change this line:
var textBox = $get("TxtBxOdaMesajlari");
to:
var textBox = document.getElementById('<%= TxtBxOdaMesajlari.ClientID %>');
Now, if you extract your javascript into a separate file or you want to use a different approach, you can emit the control id into a javascript variable from codebehind and use that instead.
In codebehind:
ScriptManager.RegisterStartupScript(this, this.GetType(), "TxtBxOdaMesajlariId", "var m_TxtBxOdaMesajlariId = '" + TxtBxOdaMesajlari.ClientID + "'";, true);
and in javascript:
var textBox = $get(m_TxtBxOdaMesajlariId);
