hi anurag,

i predict ur requirement is that u have dropdown list in page 2 with all the month names and u just passing the month name from page1 in querry string and u need to highlight the same in the ddl

if so

here is the way

in page 2

string mon=Request.Querystring["mon"].ToString();

for (int i = 0; i < ddlfedMarital.Items.Count; i++)
{
if (ddlfedMarital.Items[i].Value == mon)
{
ddlfedMarital.SelectedIndex = ddlfedMarital.Items.IndexOf(ddlfedMarital.Items[i]);

}
}

this is how u can hightlight the passed value in ddl

hope it helps u

Anurag, what happens if someone tamper/change your query string value from url?

Also make sure that before setting the selected index, clear the dropdown selection by ddlfedMarital.clearselection() as dropdownlist in asp.net does not support multiple selections and it will lead to a runtime error. It is always a good programming practice to clear selection() before setting the selected index for a dropdown.

Its a bad idea to pass values in query strings..

refer different ways to pass data across forms:

access querystring on another page like

string _monthyear=Request.QueryString["QID"].ToString();

and then add in dropdownlist as

DropdownList.Items.Add(_monthyear);
