Solution 1

You create the LinkButton object in your Page Load event but you never add it to the Page itself, so there is nothing to click. You need to add

Page.Controls.Add( lbtnHomeTopicAddress )

for the instance of the button you created to appear on the page.

I think, every time your page has a server request, it create the LinkButton. I think it does not need & it may be the reason of this problem. You can try this.

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
        LinkButton lbtnHomeTopicAddress = new LinkButton();

        lbtnHomeTopicAddress.Text = "Click here";

        lbtnHomeTopicAddress.Click += new EventHandler(this.lbtnHomeSpecificTopic_Click);

        Page.Controls.Add(lbtnHomeTopicAddress);
       }
    }

    protected void lbtnHomeSpecificTopic_Click(object sender, EventArgs e)
    {
        Server.Transfer("~/SpecificTopic.aspx");
    }
