  Hi,

  1] What is the quickest way to get an EntityFrameWork Entity from a c1TrueDBGrid1.DataSource while looping through each row in the Grid?
  
  You can use the CurrentDataBoundItem property or the GetDataBoundItem(int rowIndex) method.

  c1TrueDBGrid1.CurrentDataBoundItem;

  c1TrueDBGrid1.GetDataBoundItem(rowIndex);

  2] What is the quickest way to get an EntityFrameWork Collection from a c1TrueDBGrid1.DataSource?
  
  I recommend use methods of your data source for this case, because they will be more quickest.
  
  The GetItems method when you uses C1DataSource.

  c1DataSource1.ClientScope.GetItems();

  3] What is the quickest way to get an EntityFrameWork Entity from a c1DataSource1?
  
  4] What is the quickest way to get an EntityFrameWork Collection from a c1DataSource1?
  
  For 3-4, C1DataSource has the GetItems method:
  
  c1DataSource1.ClientScope.GetItems();
  
  When you need a filtered and ordered collection for display in the C1TrueDBGrid, then you can use the EntityViewSourceProperties, more details:
