How to get the SelectedRecord when RowBased selection enabled in GridGroupingControl - From 180948


I need help with GGC and event SelectedRecordsChanged

My problem is, when I select range of cells, I want to sum value of those cells, like excel

- If I use

gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended;

gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.None;

=> event fired, but not what I desire, and value not sum

Hi Hieudt,

When you set the ListBoxSelectionMode property to a value other than None and the AllowSelection property to None in the GridGroupingControl, a record-based selection is used. The SelectedRecordsChanging and SelectedRecordsChanged events are triggered only when using the record-based selection. In this case, the selected records can be found in the Table.SelectedRecords collection.

So, your requirement to sum the values contained in the selected range of cells in the GridGroupingControl can be achieved by using the Table.SelectedRecords property. Refer to the below code snippet,

//Case 1: Record based selection

gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended;

gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.None;


//Case 1: Record based selection

foreach (var range in this.gridGroupingControl1.Table.SelectedRecords)


     Record rec = range.Record;



     if (column.FieldDescriptor.GetPropertyType() == typeof(decimal))


         value += decimal.Parse(rec.GetValue(style.TableCellIdentity.Column.Name).ToString());
