Event to capture that a new line is added to a GridGroupingControl

[José Manuel]

Hello,

I'm looking for an event in a GridGroupingControl to inform me about a new row added because it has turned up in the datasource, other than the CurrencyManager's ListChanged event, which doesn't work for me, because record collections in the grid are not committed at that stage and I have incorrect results.

I want then to call SetCurrent on a cell of that row, to make the triangled black arrow appear on it.

Thank you very much for your help.

Try the SourceListListChangedCompleted event and check for e.ListChangedType = ItemAdded.

//subscribe to the event
     this.grid.SourceListListChangedCompleted += new TableListChangedEventHandler(grid_SourceListListChangedCompleted);

//the handler code
        void grid_SourceListListChangedCompleted(object sender, TableListChangedEventArgs e)
        {
            if (e.ListChangedType == ListChangedType.ItemAdded)
            {

            }
        }

To actually easily track the new record and set it current, you can use the SourceListRecordChanged event in addition to the SourceListListChangedCompleted event.

        Record changedRecord = null;
        void gridGroupingControl1_SourceListRecordChanged(object sender, Syncfusion.Grouping.RecordChangedEventArgs e)
        {
            changedRecord = e.Record;
        }

        void gridGroupingControl1_SourceListListChangedCompleted(object sender, Syncfusion.Grouping.TableListChangedEventArgs e)
        {
            if (e.ListChangedType == ListChangedType.ItemAdded && changedRecord != null)
                changedRecord.SetCurrent();
        }
