Hi Travis,
I'm not sure I understand your problem. Are you just trying to
maintain the selection after you databind again? You can do this by
grabbing the value *before* you bind the second time... OR you can use
EasyListBox and save yourself a whole lot of contortions.
Cheers,
Peter

Raft_IDList is a drop down control. I am selecting something and
rebuilding a bunch by re quering the database and binding. I want to
set the selected item in the drop down that I just selected but with the
rebind I don't. I tried this after I bind where items is the hashtable
of the items selected and jobid is the key.
Hashtable items = getMenuItems(sender, e); //items selected
dao.buildLogandDropDownView(items); // data access object
raft_IDList.DataSource = dao.getRaftIDView(); // gets the data view for
each drop down
raft_IDList.DataTextField = "RaftID";
raft_IDList.DataValueField = "RaftID";
raft_IDList.DataBind();
raft_IDList.Items.Insert(0, new ListItem("",""));
raft_IDList.Items.FindByValue(((String)items["jobid"])).Selected=true;
I get the following error:
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the

about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not

Any ideas how I can set the selected item in a dropdown based on a
value?
