Hi,
this doesn't work since you declare the LinkButton "lbtnTopicAddress" only locally.
Try:
LinkButton lbtnTopicAddress = new LinkButton();
protected void Page_Load(object sender, EventArgs e)
{
lbtnTopicAddress.Click += new System.EventHandler(this.lbtnSpecificTopic1_Click);
}
If you declare the LinkLabel only locally and then don't add it to the parent control it shouldn't be displayed anyway.
