Adding Item to DataBound Drop Down List
- by Stephen
Yes, I have read most of the topics here, but I can't find an answer that works.
I have Three drop-down lists. The first is databound to grab distinct experiment names. The user selects, page posts back, and the second drop-down menu displays distinct time points. This is where I need help. I need to add an item to THAT drop-down list whose ID, DataTextField, DataValueField are all TimePt.
Seems simple, but I can't get it to work.
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack)
{
TimePt.DataSource = TimePTDD;
TimePt.DataValueField = "TimePt";
TimePt.DataTextField = "TimePt";
TimePt.DataBind();
TimePt.Items.Insert(0, new ListItem("--Select---", "0"));
TimePt.SelectedIndex = 0;
}
}
I'm missing sometthing.
