This is because you are using the DetailGridTemplates collection, which is, as its name mentions, a template. This does not give you access to the actual instances of the DetailGrids. To gain access to a specific instance of a DetailGrid, you need to first get an instance of the DataRow to which the DetailGrid is attached, and then loop through the collection of DetailGrids on that row, and then the row.Cells(0).Value will return valid values.

//So first loop through the rows
For Each row as Xceed.Grid.DataRow In Me.grdTTHC.DataRows

//Then do as you did, but on the main row
For Each detail as DetailGrid In row.DetailGrids

If detail.Tag = DetailTree Then

For Each row As Xceed.Grid.DataRow In detail.DataRows
msgbox(row.cells(0).value)

Next
End If
Next
Next

I’m not sure if I understand what you are trying to do, but if you want to retrieve the rows of a DetailGrid that is attached to a master grid row, you need to do something like this :

//first, fine the master grid row you want to use, for example
Xceed.Grid.DataRow row = gridControl1.DataRows[ 0 ];
//or
//Xceed.Grid.DataRow row = ( Xceed.Grid.DataRow )gridControl1.CurrentRow;

//get the detail grid (if you have more then one detail grid, you can loop through the DetailGrids collection)
DetailGrid grid = row.DetailGrids[ 0 ];

//then retrieve the rows attached to this master grid row
foreach( Xceed.Grid.DataRow detailRow in grid.DataRows )
{
System.Diagnostics.Debug.WriteLine( .Cells[ 0 ].Value.ToString() );
}
