Question

I need to clear drpAddressTypes dropdown values except the first item and bind again that dropdownlist.

drpAddressTypes.Items.Clear();
var lstAddressTypes = repository.GetAddressTypes(userId);
if (lstAddressTypes != null)
{
  foreach (var item in lstAddressTypes)
   {
     var addressType = new ListItem(item, item);
     drpAddressType.Items.Add(addressType);
   }
}

When I am using drpAddressTypes.Items.Clear(); it is clearing all items.
How can I clear all items except the first item.

Thanks in advance. 🙂

Answer 1

You could retrive the firstitem and then clear the list and add the item again.

var firstitem = drpAddressType.Items[0];

drpAddressType.Items.Clear();
drpAddressType.Items.Add(firstitem);
