Can ComboBox be setted as readonly?

[blackiice]

I need a readonly ComboBox(user can select items,but can not edit or del the word),is it possible?

I was under the impression that the combobox is read-only?

Yes but it is a bit messy as you can type into the ComboBox and doing so resets SelectedIndex.

However (he said with an appropriate flourish!) with my ControlEvents library http://www.basic4ppc.com/forum/additional-libraries/934-controlevents-library.html and an undocumented Text property of the ComboBox

Sub Globals
    'Declare the global variables here.    
    CB1index = -1
End Sub

Sub App_Start
    Form1.Show
    CbEvents.New1("ComboBox1")
End Sub

Sub ComboBox1_SelectionChanged(I, v)
     CB1index = ComboBox1.SelectedIndex
End Sub

Sub CbEvents_TextChanged
     If CB1Index >= 0 Then ' AND ComboBox1.SelectedIndex = -1  Then
        ' the user has typed into a selection and so unset SelectedIndex so reset it
        ComboBox1.SelectedIndex = CB1index
        ComboBox1.Text = ComboBox1.Item(ComboBox1.SelectedIndex)
    Else    
        ' the useR is trying to type into the empty combobox - don't let him!
        ComboBox1.Text = ""
    End If
End Sub

Everyone should remember that the combobox has a different behaviour on the desktop and on the device.
- on the desktop, you are able to write free text into a combobox so that the selectedIndex returns -1
- on the device, it is not possible to "edit" the combobox

This seems to be a difference between .Net and .Net CF.

It's a good idea, Thanks a lot.
