Hi,

In my application i am using two pages,

In the first page having "Drop down list items" and "submit button"

if we click on this button it goes to second page

In the second page having only one button i.e "Cancel button"

if we click on this button it come back to first page.

What i want is in the first page,if we select any of the "drop down list item" then we click on submit button it's goes to second page.

here in second page if we click on "Cancel button" it come back to previous page and maintain the whatever the previous selected value in the drop down list using only "POSTBACKURL".

Please guide me..

You have (minimum) 2 options:

1) If you do not need any server side processing after clicking 'Cancel Button', you can use JavaScript and write history.go(-1) onclick of the button. That will take you to the previous page and drop-down-list will show the last selected value.

2) Store the selected value of the drop-down-list in a Session Object and assign the same when you come back to the 1st page after some server side processing on 2nd page. Something like:

C#

Session["DropDownSelVal"] = ddlSomething.SelectedValue;

And on retrival,

C#

ddlSomething.SelectedValue = Session["DropDownSelVal"];

Hope this helps!

Just enable viewstate property of Dropdownlist
like:

DropDownList1.EnableViewState = true;

Hi Brijesh,

Already i gave EnableViewState="false" for the drop down list .

Still it's not working...

Thanks

Yes you are true
actually DropDownList1.EnableViewState = true; works to retain value, but your requirement is little bit different.

For this you have to save your DropDownList selected to a variable and then as the page reloaded, make the text property of dropDownList from that variable.

Why are you misguiding OP? The way you suggested in your comment is absolutely wrong.
Get your basics clear.

And I know you down-voted my answer. But that won't change the truth.

Give a correct way or just don't give it.
Everyone does mistakes. Accepting it and rectifying it is what makes them different.

The alternate suggested by the Brijesh Kr below is also wrong. Please see my answer or the answer given by the third responder.

And why do you think that will do the job? Http is a stateless protocol and every postback will cause the page to be created once again.

hi,

try history.go-1 funtion of javascript but it browser dependent
or other option is store that value in session in the first Page
check session if it not null
then

ddl.selectedvalue = session["name"]
session["name"] = null
session.clear();
