I have three dropdownlists in my master page, when the page is redirected selected item in dropdownlists are becoming empty.So the selected items are should not be change





将选定的索引或选定的DropDrownList值存储在会话对象中。

在页面的OnLoad事件中使用此会话对象值并设置下拉列表的选定索引。

Hi,

Store the selected index or selected value of the DropDrownList in a session object.
In the OnLoad event of the page use this session object value and set the selected index of the drop down.
