Hi, in my current program i am looping all elements searching for GridNestedTables with the following code: foreach (Element em in m_syncGrid.Table.Elements) { if (em is GridNestedTable) { ... this works fine. After looping all elements i am looping all gridgroupingControl1.Table.Records. Now i''m wondering if i could get a reference to each record when looping the elements ?? I want to avoid looping the grid twice. If you could tell me what i would have to cast the element to would be great. I already tried record and others but either i don''t get any hit or the element cannot be casted in a usable manner. Thanks

If you want to get at the recrods in a GriNestedTable, you need to drill down until there is no longer a gridnestedtable as the element being looked at.
int i = 0;
foreach(Element el in this.gridGroupingControl1.Table.Elements)
{
	Console.WriteLine("{0}-{1}", i, el.GetType());
	i += 1;

	if(el != null)
	{
		if(el is GridRecord)
		{
			DataRowView drv = (el as Record).GetData() as DataRowView;
			Console.WriteLine(drv[1].ToString()); //show column 2
		}
		else if(el is GridNestedTable)
		{
			GridNestedTable gnt = el as GridNestedTable;
			GridNestedTable gnt1 = gnt;
			while(gnt1 != null && gnt1.ChildTable != null)
			{
				gnt = gnt1;
				gnt1 = gnt.ChildTable.ParentTable.CurrentElement as GridNestedTable;
			}
			foreach(GridRecord r in gnt.ChildTable.ParentTable.Records)
			{
				DataRowView drv = r.GetData() as DataRowView;
				if(drv != null)
					Console.WriteLine(drv[1].ToString()); //show column 2
			}
		}
	}
}
