i am developing a website using asp.net 3.5.i have created a cascading dropdownlist for country,state,and city.I am filling the state and city using jquery and web service.

But on page submit i am not able to get the selected value of state and city.it is returning blank.

on page load i am using this.

ListItem stateitem = new ListItem();
stateitem.Text = "Select";
stateitem.Value = "0";
dd_State.Items.Insert(0,stateitem);

I am using jquery and webservice to bind the state and city based on state.

on save button event i am getting the value as. 

obj.StateId = Convert.ToInt32(dd_State.SelectedItem.Value);

onj.CityId = Convert.ToInt32(dd_City.SelectedItem.Value);

thanks in advance.

    Since you are adding the values client-side, the page won’t know about those values because they were not generated from code-behind. This means that on each postback the dropdown will be restored from viewstate as empty so it has no item to mark as selected.
    You have at least two options:

    1. Lookup the selected value in the Form variables (the selected value is however sent to the server as a common POST behaviour)
    2. Use a hidden field in which you store the selected value via script in the onchange event of the dropdown
