推荐答案
你的开关盒没有被执行。因为条件不满意因为你的页面被刷新而导致
your switch case is not executed.Because the condition is not satisfy
due to your page is refreshed
已解决的代码为lstCinema选择索引chandged事件的浪费
The solved code Given billow for lstCinema selected index chandged event
protected void lstCinema_SelectedIndexChanged(object sender, EventArgs e)
{

if (lstCity.SelectedIndex == 1 || lstCity.SelectedIndex == 2)
{
ListItem[] items = new ListItem[3];
switch (lstCinema.SelectedItem.Text)
{
case "HI-Tech Cinema":
int ii = 0;
foreach (var item in hiTechCinema)
{
items[ii] = new ListItem(item.Text, item.Text);
ii++;
}
break;
case "Satyam Theater":
