VB.net - SelectionChangeCommitted event problem

I've a problem with the SelectionChangeCommitted event

The event is triggered when user does change, but when checking the ComboBox.text after even, the text value is the same as previous - it doesn't change.

I'm using SelectionChangeCommitted so event is only triggered when user does change to combo box, and not when any code changes the combo

Came across this http://weblogs.asp.net/grobinson/archive/2005/09/21/425711.aspx but not really sure what its saying to do

Thanks

Hello rwallacej,
What's in the event code now?
I'm using this currently in a project I'm working on and don't see that behavior...

   Private Sub ComboBox_MP_SelectionChangeCommitted(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox_MP.SelectionChangeCommitted
        MessageBox.Show("THE NEW VALUE IS: " & ComboBox_MP.Text)
    End Sub

displays
1) THE NEW VALUE IS: [the original value]

2) the combo box the changes

the messagebox appears before the combobox changes

You'll want to use:

 MessageBox.Show("THE NEW VALUE IS: " & ComboBox_MP.SelectedValue)

(or .SelectedText)

Did you try selectedValue?

Or you might try
MessageBox.Show(ComboBox_MP.Items.Item(ComboBox_MP.SelectedIndex))
