Hi nauna,
Please take refernce to the below code and correct your code.
In order to scroll you will have to add some javascript to the page to do it for you.
Code
C#
protected void Page_Load(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "", "window.onload=function(){window.scrollTo(0,document.body.scrollHeight)};", true);
}
VB.Net
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
ClientScript.RegisterClientScriptBlock(Me.[GetType](), "", "window.onload=function(){window.scrollTo(0,document.body.scrollHeight)};", True)
End Sub
