  • I'm not sure what you are looking for. Can you please explain in more detail what you are having trouble with? Where is your code failing? What is the expected result and how does it differ from the actual result?

  • hello, i want to be able to search through my SampleDataSource, this is the code i am using in my SearchResultsPage.cs and its not working.

    i have not modified the SampleDataSource that is generated automatically when you create a new SplitApp Project.

    all i want is to be able to search through this static data.

    any ideas how i can achieve that ?

  • What do you mean by searching through the datasource? Is your question about how to write a search routine?
