Setting dropdownlist selecteditem programmatically

Question

I want to set the selecteditem attribute for an ASP.Net dropdownlist control programmatically.

So I want to pass a value to the dropdownlist control to

Answer 1

var index = ctx.Items.FirstOrDefault(item => Equals(item.Value, Settings.Default.Format_Encoding));
ctx.SelectedIndex = ctx.Items.IndexOf(index);

OR

foreach (var listItem in ctx.Items)
  listItem.Selected = Equals(listItem.Value as Encoding, Settings.Default.Format_Encoding);

Should work.. especially when using extended RAD controls in which FindByText/Value doesn't even exist!
