    When processing the SelectionChanged event for a RadComboBox, the Text property of the control is not yet set with the new text value. For example, we add a RadComboBox with the SelectionChanged event set to the following OnSelectionChanged.

    private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
        RadComboBox cb = sender as RadComboBox;
        Trace.TraceInformation("cb.Text = {0}", cb.Text);

    When we start typing in the Combo Box, the displayed text is always the Text value before the latest character. So,l when we type 1, cb.Text is null, when we type 2, the combo box displays "12", but cb.Text is 1.

    How can we see the current value of the text box when the selection is changed?

    Hi Richard,

    You could try getting the Text using a Dispatcher like this:

    Dispatcher.BeginInvoke(new Action(() =>
        Trace.TraceInformation("cb.Text = {0}", cb.Text);

    Let us know whether this will work for you.
