Composite C1: How to retrieve data from datatypes?

Question

I'm attempting to create more dynamic slider so I've created a custom datatype which one includes fields like Caption, Text, Link, Image, StartDate, EndDate, Active, etc... I hope I'm in the right path.

Now I need to retrieve active entries. How can I get the necessary entries?

You query data using LINQ through the Get method on the Composite.Data.DataConnection class - dataConnection.Get<T>() where T is your data type wield an IQueryable.

Below is code that will query a data type named Your.Data.Type, filtering on the Caption field and selecting Caption, Text, Image and StartDate.

using  (DataConnection connection = new DataConnection())
{
   var myData = 
      from d in connection.Get<Your.Data.Type>()
      where  d.Caption == "My Caption"
      select new { d.Caption, d.Text, d.Image, d.StartDate };
}

On the Composite C1 documentation website you can read more about accessing data with C#.

If you are not into C# you can use either Visual Functions or XSLT Functions.
