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");
}
</script>

And in asp.cs file I have
protected void BttnGonder_click(object sender, EventArgs e)
{
string cariId = "";
if (KullaniciTuru == 1)
{
cariId = Session["ModelId"].ToString();
}
else
{
cariId = Session["UyeId"].ToString();
}
string uyeHesapAdi = BAL.Cari.Cari.GetCariHesapAdi(int.Parse(cariId));
string mesaj = uyeHesapAdi + " : " + TxtBxMesaj.Text;
TxtBxOdaMesajlari.Text = TxtBxOdaMesajlari.Text + Environment.NewLine + mesaj;
//TxtBxOdaMesajlari.Focus();
ScriptManager.RegisterStartupScript(this, this.GetType(), "txtbxmesajlarslide", "buttonClicked();", true);
TxtBxMesaj.Text = string.Empty;
}
My problem is that buttonClicked() function is not working anymore, I tried to use Page.ClientScriptManager.RegisterClientScriptInclude from ScottS's answer and also this Page.ClientScript.RegisterClientScriptBlock , neither of them worked.What can I do?
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.
