    Disable ListItem in Drop Down List

    I am trying to disable a list item in a drop down list.

    The list looks something like

    "Item 1

    Other items that may interest you

    Item 2
    Item 3"

    So items with an index of 1, 2 and 3 should not be selectable as I do not
    want them to fire the onselectedindex change.

    I know that there is an enabled property but that this does not apply to
    dropdownlists.

    Does anyone know of another way I can disable these items?

    Thanks for your help.

      Just remove the unwanted items from the list, then users can't select them.

          Obviously that would be nice but I need to keep them in there!

              I'm not aware of any way to do this in the way that you want. The only way
              I can think of to do something like this is to handle it manually.

              For instance if you don't want to allow "Item 2" to be selected, you could
              use something like:
              Private Sub ComboBox1_Selec tedIndexChanged (ByVal sender As System.Object,
              ByVal e As System.EventArg s) Handles ComboBox1.Selec tedIndexChanged

              If ComboBox1.Selec tedItem.ToStrin g() = "Item 2" Then
              ComboBox1.Selec tedIndex += 1

              End Sub

              Of course, this has a couple of problems such as incrementing past the last
              item, etc. What you would have to do is keep track of the current value of
              ComboBox - then depending on whether you allow the change, update the
              manually tracked value and allow the change or manually set the combo box
              back to the value stored previously.

                  Possible use the Validation events, Causes Validation property?
