How can I retrieve the current cell value in GridGroupingControl

Hi, I try to get the current cell value in a GridGroupingControl. How can I do this? GridGroupingControl is a little bit different from GridControl and GridDataBoundControl, right?

You can get the current record with Record r = groupingGrid.Table.CurrentRecord the record object provides methods to get values, e.g. r.GetValue("CustomerID"). You can also get the underlying DataRow when you call r.GetData(). That will return the DataRowView element for the record. You can get at the currentcell using gridGroupingControl1.TableControl.CurrentCell.

Here is code to get the value in a flat grouping grid. Record r = gridGroupingControl1.Table.CurrentRecord; int col = this.gridGroupingControl1.TableControl.CurrentCell.ColIndex; int field = this.gridGroupingControl1.TableDescriptor.ColIndexToField(col); object o = r.GetValue(this.gridGroupingControl1.TableDescriptor.Fields[field]); Console.WriteLine(o);

But if current cell belongs to nested table?... This way works for parent table only.

You have to walk down the parent-child table chain to find the proper parent table.
private void button1_Click(object sender, System.EventArgs e)
{
	Element el = this.gridGroupingControl1.TableControl.Table.CurrentElement;
	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;
			}
			DataRowView drv = gnt.ChildTable.ParentTable.CurrentElement.GetData() as DataRowView;
			if(drv != null)
				Console.WriteLine(drv[1].ToString()); //show column 2
		}
	}
}

Console.WriteLine(drv[1].ToString()); //show column 2 And how to access to CURRENT CELL here ?

Once you have the nested table, you can use it to get the associated TableControl. From the tableControl, you can use the same code as above to access the currentcell in that TableControl.
private void button1_Click(object sender, System.EventArgs e)
{
	Element el = this.gridGroupingControl1.TableControl.Table.CurrentElement;
	if(el != null)
	{
		if(el is GridRecord)
		{
			Record r = el as Record;
			int col = this.gridGroupingControl1.TableControl.CurrentCell.ColIndex;
			int field = this.gridGroupingControl1.TableDescriptor.ColIndexToField(col);
			object o = r.GetValue(this.gridGroupingControl1.TableDescriptor.Fields[field]);
			Console.WriteLine(o);
		}
		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;
			}
			Record r = gnt.ChildTable.ParentTable.CurrentRecord;
			string name = gnt.ChildTable.ParentTable.TableDescriptor.Name;
			GridTableControl tableControl = this.gridGroupingControl1.GetTableControl(name);
			int col = tableControl.CurrentCell.ColIndex;
			int field = gnt.ChildTable.ParentTable.TableDescriptor.ColIndexToField(col);
			object o = r.GetValue(gnt.ChildTable.ParentTable.TableDescriptor.Fields[field]);
			Console.WriteLine(o);
		}
	}
}
