Equivalent of TableDescriptor.ColIndexToField() but for Rows--> Records ?

Basically I want to handle a key event in a gridgrouping control and do some stuff with the current selection. However I cant see where I can translate these row/col indexes to actual record indexes. See the following for where I''m code going with this: private void TableControl_KeyDown(object sender, KeyEventArgs e) { if ( e.KeyCode == Keys.D && e.Modifiers == Keys.Control ) { if ( gridGroupingControl1.TableControl.Selections.Count == 1 ) { foreach ( GridRangeInfo info in gridGroupingControl1.TableControl.Selections.Ranges ) { for ( int j=info.Left; j <= info.Right; j++ ) { int fieldIndex = gridGroupingControl1.TableDescriptor.ColIndexToField(j); for ( int i=info.Top; i <= info.Bottom; i++ ) { //I''m looking for something like: //int recordIndex = gridGroupingControl1.TableDescriptor.RowIndexToRecord(i); //Record record = gridGroupingControl1.TableModel.Table.Records[recordIndex]; } } } } } }

Daniel, there is a one-to-one relation between rowindex and the Table.DisplayElements collection. If you have a rowIndex you can get the element that is displayed at that row with Element el = Table.DisplayElements[rowIndex]; The record the element belongs to will be Record r = el.ParentRecord; The record position in the table can then be determined with int index = Table.Records.IndexOf(r); or the record position in the underlying source list with int orginalIndex = Table.UnsortedRecords.IndexOf(r) BTW - if you have an element and want to know the rowindex it is displayed at you can do this: int rowIndex = Table.DisplayElements.IndexOf(el); Stefan
