Is this data driven ? If it's not, why is it being set in code ? You add items to ListBox_Tag.Items in order to add them to the control. I am not sure if ListBox has a datasource/databind paradigm as well, that works best if you have a data based collection to add. Either way, read the documentation, use the intellisense to explore and try some things, it's really reasonably self documenting.

Solution 4

C#

ListBox_Tag.Items.Add("Item1");
ListBox_Tag.Items.Add("Item2");
ListBox_Tag.Items.Add("Item3");

And in ASP.NEt you have viewstate and postsbacks to worry about so to pupulate it even when buttons are pressed remember the

C#

if(!IsPostback){

}

to encode your adds
