How to know the Parent Row of the GridGroupingControl

[Ramana]

I'm using GridGroupingControl.I have two tables t1 and t2 which are related through the column "Description" .t1 is parent of t2.When I click on any DataGrid cell of child table, how can i know to which parent row it is related to?. The rows of parent table may contain the same child rows as other child row.

Thanks & Regards,
Ramana.

Hi Ramana,

Thanks for your interest in Syncfusion Products.

You can get the parent row details to which a particular child record belongs by accessing the DisplayElement. Please refer to the following code handled in TableControlCellClick event.

GridTableCellStyleInfo style = e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex);
if (style.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell || style.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell)
{
     if (style.TableCellIdentity.Table.TableDescriptor.Name == "ChildTable")
     {
          Element ele = style.TableCellIdentity.DisplayElement;
          Element el = ele.ParentTable.RelationParentTable.CurrentElement;
          Record r1 = el.GetRecord();
          if(r1 != null)
               MessageBox.Show(r1.Info);
     }
}

This code triggers the message box with parent record details when a child record is clicked.
