code behind:

C#

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ConnectionString);
        con.Open();
        SqlCommand cmd = new SqlCommand("select * from UserInformation where UserName =@username and Password=@password", con);
        cmd.Parameters.AddWithValue("@username", txtUserName.Text);
        cmd.Parameters.AddWithValue("@password", txtPWD.Text);

Did your designer page get altered some how? You may just need to recreate the controls.

Update your web form designer.aspx.cs file.

How can you update designer.aspx.cs:

1. Remove (Cut) control from page.
2. Paste it again on same position.
3. check designer.cs file where instance has been created like:

C#

/// <summary>
        /// txtPWD control.
        /// </summary>
        /// <remarks>
        /// Auto-generated field.
        /// To modify move field declaration from designer file to code-behind file.
        /// </remarks>
        protected global::System.Web.UI.WebControls.TextBox txtPWD;
