    <p>One of our testers, managed to set a slider bound variable to 18888888888888888 which can only take values between 1-100 normally. (I can observe it in view model which is saved to a xaml file.) What's special about this number?</p> <p>Here are some details. The application has a slider, it is bound to an observable property in a view model. Normally, when application saves the workspace, this viewmodel is saved along using XamlServices.Save. My tester reported some awkward behaviour, the value of the slider showing -214 upon loading this project. I asked him to send me the file and the value in the saved xaml contains my mysterious number. </p> <p>I know this is the result of a bug in my code, or some other library code. I will hopefully nail it down. However, normal "garbage" values cannot be like this. When I google, I see some non-programming related pages, which shows somehow this number was generated in history of internet (so it's not my cat's doing). In short, I am trying to figure out, how this number can be created in the first place, like when you see INT_MAX + 1, if you are experienced enough you can recognize it (-2137483648 anyone?). </p>

    2. CO@KorayBalci: Can you repro? Closed because there's really no definitive answer, thus all that remains is speculation.

    3. CO@SLC and Will, I don't know if I am not clear enough, probably this is the result of a bug, an overflow most probably. I will try to repro and debug. However, you cannot tell me that this is just a random number at all, a 1 followed by 16 8s? It should be a side effect of a bug but I am curious how it can be produced. Just google the number only, there are some weird occurences, probably result of a similar bug (and their authors probably not even aware of the issue). Or, I am just trolling and posting an awkward number for fun, but this is no ordinary random number. Hope I am clear.

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.
