如何将参数从通用处理程序文件传递到ASPX页面

Question

I want to show a specific persons identity on an aspx page on page load (data includes photo, name, .. etc) On aspx page loading, handler file runs in backhand i fetch data from database, inside this handler file. i used handler, for to convert image; otherwise i would just use aspx page load. But had to return also other columns too for the specific record).

And gotto return data to aspx page and show in aspx controls like; image control, label control.. etc.

Is it possible to access an aspx page's server control id, from a generic handler ashx file? For example, inside ashx file, can i assign a value to a label control which belongs to an aspx page?

Or, are there any other ways to pass parameters to an aspx page from an ashx file? Simply, I want my ashx file return an object record to aspx page, and Show the record in asp.net controls.

如果在页面“打开”时显示图像和其他数据，则应该只在页面加载事件中从数据库中读取数据，然后更新页面控件。
