Link Button in asp.net click event not firing

Question

<asp:LinkButton ID="lbDownloadFile" name = "lbDownloadFile" runat="server" CausesValidation="false" 
                            onclick="lbDownloadFile_Click" />

I have this link button. on click:

protected void lbDownloadFile_Click(object sender, EventArgs e)
{    //here is my debug pointer/breakpoint
    .........................
}

but this event is not firing. my Page_Load() event is firing. How to solve this problem?

protected void Page_Load(object sender, EventArgs e)
{
    if(!IsPostBack)
    {
        if (Session[Antrage_AnfrageSessionNames.AgntNr] == null)
        {
            Response.Redirect("../UserSessionError.aspx");
        }

        try
        {
            if (Request.QueryString["Kundennummer"].ToString() != null)
            {
                //If kundennummer exists in QueryString then stores it to further use 
                kundennummer = Request.QueryString["Kundennummer"].ToString();                    
            }
        }
        catch
        {
            kundennummer = string.Empty;
        }
    }
}

EDIT:

I am adding the code, what FireFox firebug shows me respective to the LinkButton.

I think the auto generated href is the main problem here.

Solution

I have created demo project and copy same code as you have written.It is working fine

  <asp:LinkButton ID="lbDownloadFile" name = "lbDownloadFile" Text="Click me" runat="server" CausesValidation="false" OnClientClick="lbDownloadFile_Click"
                            onclick="lbDownloadFile_Click" />

in code behind file

  protected void lbDownloadFile_Click(object sender, EventArgs e)
        {    //here is my debug pointer/breakpoint
        }

I have just added text on link button.

I think the OP have dynamically added the Text . This is not a problem, This problem coming from page-load event. But OP did't put that code. :)
