cyq.data自动绑定MActionUI.cs修改

cyq.data的自动赋值取值都是依据控件前三位后边的为字段依据，修改了一下。改成如果不使用SetAutoPrefix方法，则自动获取和字段一一对应的数据，使用SetAutoPrefix方法后才使用指定的前缀。

protected void Page_Load(object sender, EventArgs e)
{
    UserName.Text = "";
    UserPwd.Text = "";
    RealName.Text = "";
    Email.Text = "";
    Mobile.Text = "";
    MAction action = new MAction("Base_Admin");
    action.Fill("id=1");
    action.SetToAll(this);
    action.Close();
}
 
protected void Button1_Click(object sender, EventArgs e)
{
    MAction action = new MAction("Base_Admin");
    //action.Set("username", "123123");
    action.Insert(true);
    action.Close();
}

  上边这种是把数据直接绑定到页面，控件ID和数据库字段一一对应。再新增插入的时候也无须指定控件前缀，默认取数据库字段名。

protected void Page_Load(object sender, EventArgs e)
{
    UserName.Text = "";
    UserPwd.Text = "";
    RealName.Text = "";
    Email.Text = "";
    Mobile.Text = "";
    MAction action = new MAction("Base_Admin");
    action.Fill("id=1");
        action.SetAutoPrefix("txt","ddl");
    action.SetToAll(this);
    action.Close();
}
 
protected void Button1_Click(object sender, EventArgs e)
{
    MAction action = new MAction("Base_Admin");
    //action.Set("username", "123123");
        action.SetAutoPrefix("txt","ddl");
    action.Insert(true);
    action.Close();
}   

 这种是指定了控件前缀，把所有已txt、ddl开头连上数据库字段的控件绑定，插入的时候插入txt、ddl开头的和数据库字段对应的数据。

这样如果字段和控件直接对应的情况，就不用考虑SetAutoPrefix方法了。用了SetAutoPrefix方法，则和以前的cyq一样使用。
