Asp.net - Add blank item at top of dropdownlist

Question

Why is the dropdown not showing my blank item first? Here is what I have

drpList.Items.Add(New ListItem(\"\", \"\"))

With drpList
    .DataSource = myContro

I think a better way is to insert the blank item first, then bind the data just as you have been doing. However you need to set the AppendDataBoundItems property of the list control.

We use the following method to bind any data source to any list control...

public static void BindList(ListControl list, IEnumerable datasource, string valueName, string textName)
{
    list.Items.Clear();
    list.Items.Add("", "");
    list.AppendDataBoundItems = true;
    list.DataValueField = valueName;
    list.DataTextField = textName;
    list.DataSource = datasource;
    list.DataBind();
}
