  Hi.
  
  I have a large system we are developing constantly which displays around 100 lists throughout the system. We have set up a configuration system for the lists, and 1 user control to handle them all.
  
  All our datasources are custom classes.
  
  When I need to combine two different properties of the class into 1 column, things get a bit tricky.
  
  Example of a custom class:
  

  public class Master {

  public int ID { get; set; }

  public string Name { get; set; }

  public Child FirstChild { get; set; }

  }

  public class Child {

  public int ID { get; set; }

  public string Name { get; set; }

  }

  
  Using reflection I can access the values of the Master class easily. This is the databind event of the custom ItemTemplate class:
  

  void control_DataBinding(object sender, EventArgs e) {

  LiteralControl control = (LiteralControl)sender;

  GridDataItem container = (GridDataItem)control.NamingContainer;

  control.Text = dataItem.GetType().GetProperty("Name").GetValue(dataItem, null).ToString();

  }

  
  
  
  
  But when I need values from the Child class, things get tricky. I have tried all methods thinkable to me, and am stuck with this.
  
  Can anyone show me how I can access the values from the Child class?

  Did you try using DataBinder.Eval? Here is an example:
  
  

  var container = (GridDataItem) control.NamingContainer;

  var value = (string)DataBinder.Eval(container.DataItem, "FirstChild.Name");
