I have a listbox containing a list of items coming from the database. When I select an item from the listbox, i want to display some attributes of the selected item. I am not able to trap the event which is getting fired when I select an item in the listbox. I have written code on listbox selected index change event which is firing only for the 0th index and not firing when I am changing the selection from 0th item to any other item.

Below is the code which I have written on selected Index change event:

int intSelectedFile = 0;
DataTable dtfileAttributes = new DataTable();
LegacyMaster objLgcy = new LegacyMaster();

DataRowView dRow = lstFiles.SelectedItem as DataRowView;

intSelectedFile = Convert.ToInt32(dRow[0]);

dtfileAttributes = objLgcy.GetFileAttributes(intSelectedFile);

DisplayFileAttributes(dtfileAttributes);

0	Very frequently people forget to specify AutoPostback=true property for the ListBox, see if you have written that. If this is already there then make sure that you are populating the ListBox in !IstPostback in the Page_Load method (in case of asp.net). Hope this will help.
