It is up to the tour developer to ensure that the visual elements are available. There are use cases (e.g. moving to another tab during on entering step) where the element is not loaded for the current step, but it will be loaded before navigation to the next step will be executed.

Hi,
I have an issue with proper position of the tour popup when hosting window's size changes or when it's being moved to another position.

I tried demo app and everything works fine there, but when I prepared the most simplest test app of mine, nothing works as it should.

Check this - app on normal start looks good

but when I move window popup does not move with the attached element

It behaves the same when I resize the window.

Here's demo app
FeatureTourTest.zip

Can you help me please? What have I done wrong?

Edit: I have just noticed that when I use button placed directly into window element it works, but when I use button placed in usercontrol that is placed in the window it does not. Is there any way how to make Tour working from user controls?

Goal
Need to put a popup over Name header in DataGrid

Attempts
Tried to set ElementID through style or directly, in turn

<Style x:Key="TourNameHeaderStyle" TargetType="{x:Type DataGridColumnHeader}">
    <Setter Property="tour:TourHelper.ElementID" Value="Name"/>
</Style>

<DataGridTextColumn Binding="{Binding name}" HeaderStyle="{StaticResource TourNameHeaderStyle}">
    <DataGridTextColumn.Header>
        <TextBlock Text="Name" tour:TourHelper.ElementID="Name"/>
    </DataGridTextColumn.Header>
</DataGridTextColumn>

Result
Can not find Name in both cases

Could not find visual element with ElementID 'Name'.
Popup may not occur. Ensure that the visual element is available in the current view.

Reason?
Guess, it's because DataGridTextColumn is not in the same visual tree as rest elements.
VisualTreeHelper is used everywhere in ThinkSharp.FeatureTouring.Helper.WpfUtils.

Workaround
Fake Control over the header is not an option since columns can be resized, reordered, shrunk by main window, etc.

Question
Is it possible to overcome this?

• Remove licensing code
• Remove company related stuff

It is possible to execute custom code on step entering:

navigator.OnStepEntering("StepName").Execute(step => { /* action */ });

That work fine if the element, associated with the next step, is visible or invisible. However, the element has to be loaded! If the element was not loaded before, the action will not be executed. That may be a problem, because OnStepEntering may be used to prepare the application's state for the next step (e.g. ensure that the desired element is visible).

It should be possible to access the number of total steps and the current step number for realizing advanced navigation lables
