What is the problem ?
Do you get any exceptions ?

A client script is uniquely identified by its key and its type. Scripts with the same key and type are considered duplicates. Only one script with a given type and key pair can be registered with the page. Attempting to register a script that is already registered does not create a duplicate of the script.

Please ensure that the key "ClientScript" is unique.

Another simple alternative is

C#

Response.Write("<script type="text/javascript">");
Response.Write("alert('"+ex.Message+"');");              
Response.Write("</script>");

Try this:

C#

Page.ClientScript.RegisterStartupScript(this.GetType(), "Error1", string.Format("<script type='text/javascript'>alert('{0}'); location.href='AddTender.aspx';</script>", ex.ToString().Replace("'", "\\'")));
