How to enable a disabled dropdown,textbox from cs file C#

 public void fill_name_selectedindexchanged(object sender, EventArgs ex)
{
    //txt_name.Enabled = true;
    ddl_title.Attributes.Add("enabled", "enabled");
    txt_full_name.Attributes.Add("enabled", "enabled");
    txt_login_name.Attributes.Add("enabled", "enabled");
    txt_email.Attributes.Add("enabled", "enabled");
    txtDefaultCompany.Attributes.Add("enabled", "enabled");

    //txt_name.Text = "";
    ddl_title.Items.Clear();
    txt_full_name.Text = "";
    txt_login_name.Text = "";
    txt_password.Text = "";
    txt_email.Text = "";
    AutoCompleteExtender1.ContextKey = ddl_user_type.SelectedValue.Trim();
    string val = ddl_user_type.SelectedValue;
    if (val.Trim() == "N")
    {
        ddl_title.Attributes.Add("enabled", "enabled");
        txt_full_name.Attributes.Add("enabled", "enabled");
        txt_login_name.Attributes.Add("enabled", "enabled");
        txt_email.Attributes.Add("enabled", "enabled");
        txtDefaultCompany.Attributes.Add("enabled", "enabled");
        txt_full_name.Text = "";
        txt_login_name.Text = "";
        txt_email.Text = "";
        mm.getlookup(ddl_title, "title", "u");
    }
}

The dropdown and the textbox remains disabled,it doesn’t change to enable.

in addition to the ans given by Rody.
i wanna add that u can put an attribute disabled and its value to disabled to disable but
there is no attribute enabled. to enable an html input control you will have to remove the disabled attribute and not add an enabled attribute
