Combobox clears itself

What the!...

First of all I tried to detect in Private Sub Combo1_Change()
the difference between Combo1.listindex = -1 and higher (selected in the dropdownbox), but it didn't work in VB.NET.
(In VBA it works perfectly!)

So I tried it differently:
I've made parallel to the change sub an 'click sub' to detect
the clicking in the dropbox.
If I fill my combobox and click in de dropdownbox,
then the combobox.text clears itself!

Does anyone know how to code the detection of changing the combobox through writing and change by selecting something in the dropbox?

Please help, I'v tried to much...

UR problem is not corectly displayed
put ur code and ask ur problem

Have you tried the "SelectedIndexChanged" Event?
I used this when I was programming with C#. Every times when you select the combobox, it fires this event.

I don't know will it help....

I don't know will this help. I searched from http://www.msdn.com

You can change the showSelectedButton_Click event into Combo1_SelectedIndexChanged event and try the following

VB Code:

Private Sub showSelectedButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
    Dim selectedIndex As Integer
    selectedIndex = comboBox1.SelectedIndex
    Dim selectedItem As Object
    selectedItem = comboBox1.SelectedItem
 
    MessageBox.Show("Selected Item Text: " & selectedItem.ToString() & Microsoft.VisualBasic.Constants.vbCrLf & _
                        "Index: " & selectedIndex.ToString())
End Sub

Thanks, I'll try it!
(The code is to long to display. in short the problem occurs after the click function has ended. With F8 during the walkthrough everything looks normal en what's selected is displayed in de combobox, but with 'end sub' it's gone. But I will try SelectedIndexChanged)

You seem to be saying that this is a VB.Net problem so I've moved the thread to the VB.Net forum.
