Sorry, should have been clearer in my original post; the thing I want to hot track is the text in the combo when it is rolled up and not in edit mode.  All the rest of the editors (text boxes, ultracomboeditors etc.) can change colour when I hover the mouse over their text areas, but not the ultracombo?  It's very obviously not consistent when you are moving the mouse around in the UI?

Hi Tom,

It looks like AppStylist doesn't have a HotTracked state for UltraCombo. If you would like to have behavior like this in your application, you can do it in code. Try handling the following methods in your application.

private void ultraCombo1_MouseEnterElement(object sender, Infragistics.Win.UIElementEventArgs e)
{
    if (e.Element is UltraComboUIElement)
    {
        UltraCombo combo = sender as UltraCombo;
        if (sender != null)
        {
            // originalColor will need to be defined outside the scope of this method
            originalColor = combo.Appearance.BackColor;
            combo.Appearance.BackColor = Color.Red;
        }
    }
}
private void ultraCombo1_MouseLeaveElement(object sender, Infragistics.Win.UIElementEventArgs e)
{
    if (e.Element is UltraComboUIElement)
    {
        UltraCombo combo = sender as UltraCombo;
        if (sender != null)
        {
            // originalColor will need to be defined outside the scope of this method
            combo.Appearance.BackColor = originalColor;
        }
    }
}

Hi Mike

Thanks very much for that.  I didn't use the solution exactly as you have it because I already had some other code that set the text colour depending on some other factors, but the events were just what I needed to trigger all of that.

I think there should be an app stylist setting for that though, every other control has it and doing the above for every combo in a big system would be a real nuisance.

Cheers, Tom
