Hi RD,
As your description, you cannot add items for the dropdownlist in the content page's load event. Is it right?
I have a test, it works fine, below is my test code in the content page codebehind.
public partial class TestDropDownList_Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
ListItem LI = new ListItem();
LI.Text = "Selected Item";
LI.Value = "select";
this.DropDownList1.Items.Add(LI);
}
}
How about your code?
Please remember to mark the replies as answers if they help and unmark them if they provide no help.
Yours sincerely,
