AnkitPal says:

protected void btnsave_Click(object sender, System.EventArgs e)

        {

            //connectionstrings

            cnn.Open();

             

            //insert command

            cmd.ExecuteNonQuery();

            {

                string script = @"<script language = ""javascript"">

                alert('Dear Student Your Query has been Sent to ECC.');

                </script>;";

                Page.ClientScript.RegisterStartupScript(this.GetType(), "myJScript1", script);

            }

        }

 Replace the above with the below code.

protected void btnsave_Click(object sender, System.EventArgs e)
        {
            //connectionstrings
            cnn.Open();

            //insert command
            cmd.ExecuteNonQuery();
            string script = @"<script language = ""javascript"">
            alert('Dear Student Your Query has been Sent to ECC.');
            </script>;";
            Page.ClientScript.RegisterStartupScript(this.GetType(), "myJScript1", script);
            Response.Redirect(Request.Url.AbsoluteUri);            
        }
