HI,

Use the selectedIndexChanged method for your purpose. A sample code below for reference.

XML

protected void ddlCountry_SelectedIndexChanged(object sender, EventArgs e)
   {
       IList<State> states = GetStateList(GetCountryList()[((DropDownList)sender).SelectedIndex]);
       ddlStates.DataSource = states;
       ddlStates.DataBind();
   }
