Question

I have a popup in my application which is activated by a change in selected value of a combobox.
It works fine when I debug in VS 2010 but it doesn’t fire when I use the .exe on the same computer.

Is there an additional property of the popup I should use to make it stay on when using .exe?

 private void trigger_mode_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        MODE = trigger_mode.SelectedValue.ToString();
        switch (Convert.ToString(trigger_mode.SelectedValue))
        {
            case "triggerModeData":
                Popup_data.Placement = System.Windows.Controls.Primitives.PlacementMode.Mouse;
                Popup_data.StaysOpen = false;
                Popup_data.Height = 200;
                Popup_data.Width = 250;
                Popup_data.IsOpen = true;
                break;

            case "triggerModeRepeat":
                Popup_repeat.Placement = System.Windows.Controls.Primitives.PlacementMode.Mouse;
                Popup_repeat.StaysOpen = false;
                Popup_repeat.Height = 200;
                Popup_repeat.Width = 250;
                Popup_repeat.IsOpen = true;
                break;
        }
    }

XAML code

 <Popup x:Name="Popup_repeat" AllowsTransparency="True">
        <StackPanel Background="BurlyWood">
            <TextBlock TextWrapping="Wrap" Name ="T1" Text="Please enter the time interval between triggers in milliseconds"/>
            <TextBox Name="T2" Text="Enter value here" KeyDown="T2_KeyDown"/>
            <TextBlock TextWrapping="Wrap">

If you need the popup to remain open to receive input, you’ll need to set the StaysOpen property to True. Otherwise, the popup will close as soon as focus or activation leaves the popup.
