    <p>I've run into the following problem:</p> <p>I've got a user control, on which I'v got a chart component developed by me. I'm trying to use the user control in the main application, and reach the chart component member from the main app's code something like this:</p> <pre><code>((VibraLysisUserControls.UC_SensorMonitor)(docContent.Content)).TimeDomainGraph </code></pre> <p>where TimeDomainGraph is the copmonent which resides in separate the dll in the project. The interesting point comes here: When I put the above line into the code behind I've got the following error message in compile time:</p> <blockquote> <p>'VibraLysisUserControls.UC_SensorMonitor' does not contain a definition for 'TimeDomainGraph' and no extension method 'TimeDomainGraph' accepting a first argument of type 'VibraLysisUserControls.UC_SensorMonitor' could be found (are you missing a using directive or an assembly reference?)</p> </blockquote> <p>If I comment out that line and go to debug the application, I can reach that member in the QuickWatch window when I stop the app at the point where I would like to use this. In fact, I just copied the code from the QuickWatch window, where it works perfectly.</p> <p>Anybody has some idea, what the hell is going on here? Why I can't reach a property in the code, which works just perfectly in the QuickWath window during debugging?</p> <p><strong>Update:</strong></p> <p>The problem is solved. I found out with some help. It was a visibility problem in XAML. Thanks for your help.</p> <p>Br, Csaba</p>

    1. COIt can be a matter of class hierarchy (TimeDomainGraph, for example, is defined in some class that inherits from uc_sensormonitor). Your code is not enough to tell, though

    2. COKindly check the access specifier for the Method "TimeDomainGraph" . Also check the definition once.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
