Title:Not able to retain the values in a session drop-down list

On logging-in the website, selecting input values from a drop-down list, a grid view appears. On selecting a link from the grid-view, control is rightly transferred to the next-page. But on clicking the back-button (designed on the page), the previous grid-view rightly appears but the input values in the drop-down list are gone, which I want to be displayed or selected.

Please suggest a solution.

我同意ankur的观点，如果不看代码就很难说.
但如果您将下拉列表值保留在会话或查询字符串中，则仍然可以使用.
并重定向到其他页面，然后当您按下后退"按钮时，请检查您从哪个页面重定向.如果您从选定的链接按钮重定向，则将下拉列表的选定值分配为会话值或查询字符串值，否则将其保留为默认值.最好将其保留在会话&当您将从链接按钮重定向到其他页面时将其删除

I am agree on ankur''s point it is difficult to say without seeing a code.
but still if you keep your dropdown value in session or in querystring.
and redirct to other and when you press a back button check from which page you are redirecting. if you redirect from the selected link button then assign the selected value of the dropdown as session value or querystring value otherwise keep it default.It is better if you keep it in session & removed it when you will redirecting to other page not from link button
