问题描述

我正在网格视图中使用下拉列表.

我在ddl中有预定义的数据.我正在使用分页.

我在第一页.我在ddl中有一些数据.我更改了ddl中的数据，然后转到第二页.如果我从第二页回到第一页，则它不会保留更改后的值.它正在获取默认值.

我想从第二页回到第一页后保留这些值.

Hi,

I am using drop down lists in grid view.

I have predefined data in ddl. I am using pagination.

I am in first page. I have some data in ddl. I changed data in ddl and going to second page. If I come back to first page from 2nd page, it is not retaining changed values. It is getting default values.

I want to retain the values after coming back to first page from second page.

It would be great if u can help me out in this regard.

Thank you so much in advance.

推荐答案

不要在设计器中预定义数据，在Page_Load期间填充数据并将填充内容包装在

Don''t predefine the data in the designer, fill it during Page_Load and wrap the filling in a

if(!IsPostBack)
{
<fill the ddl here>
}

确保ddl的EnableViewState为true.

那应该保持您在此会话期间所做的任何更改.

Make sure EnableViewState is true for the ddl.

That should maintain any changes you make (during this session).
