I have a custom server control (composite control having dynamically created dropdown boxes and textboxes). I have enabled AJAX in order to avoid page reload.The server control is used inside the ASP.NET webcontrol having few buttons which controls the visibility of the server control. Now I enter values in the dropdown box and texboxes and click on any other button. After this postback the last entered values are gone! The control is not remembering the values. Can anyone help me? How can I retain the values after post back?

推荐答案

确保控制是每次回发后给予完全相同的ID。你可能也想尝试Page_Init如果可能的话在初始化动态控制（的DropDownList和TextBox）。

Ensure that the controls are given the exact same ID after each postback. Also you might want to try initialising your dynamic controls (DropDownList and TextBox) during Page_Init if possible.
