SFDataGrid is throwing an error intermitandly

[anooj baby]

Hi,

I have a datagrid having a list as datasource.

It binds data as shown below

private void LoadRecordingGrid(List<ProcedureDataHeader> recordingData)

        {

            if (recordingData == null) return;

            if (recordingData != null && recordingData.Count > 0)

            {

                List<ProcedureDataHeader> recordingList = new List<ProcedureDataHeader>(recordingData);

                using (ProcedureDataHeaderManager dataHeaderManager = new ProcedureDataHeaderManager())

                {

                    byte[] notificationIcon = dataHeaderManager.ImageToByteArray(Images.NotificationReportIcon.ToBitmap());

                    recordingList.Where(m => m.UseNotification).ToList().ForEach(m => m.RecordingIcon = notificationIcon);

                }

                dgvRecordings.DataSource = recordingList;

                dgvRecordings.SetCustomFilterIcons();

                this.dgvRecordings.RecordContextMenu = this.contextMenuStripEcg;

            }

            else

            {

                this.dgvRecordings.RecordContextMenu = null;

            }

            dgvRecordings.Columns[0].HeaderText = "";

            dgvRecordings.ClearSelection();

        }

Grid Settings are :

this.dgvRecordings.AccessibleName = "Table";

            this.dgvRecordings.AllowEditing = false;

            this.dgvRecordings.AllowGrouping = false;

            this.dgvRecordings.AutoGenerateColumns = false;

            this.dgvRecordings.AutoSizeColumnsMode = Syncfusion.WinForms.DataGrid.Enums.AutoSizeColumnsMode.AllCellsWithLastColumnFill;

this.dgvRecordings.Columns.Add(gridImageColumn1);

            this.dgvRecordings.Columns.Add(gridTextColumn1);

            this.dgvRecordings.Columns.Add(gridTextColumn2);

            this.dgvRecordings.Columns.Add(gridTextColumn3);

            this.dgvRecordings.Dock = System.Windows.Forms.DockStyle.Fill;

            this.dgvRecordings.Location = new System.Drawing.Point(0, 0);

            this.dgvRecordings.Name = "dgvRecordings";

            this.dgvRecordings.PreviewRowHeight = 35;

            this.dgvRecordings.RecordContextMenu = this.contextMenuStripEcg;

            this.dgvRecordings.SerializationController = null;

            this.dgvRecordings.Size = new System.Drawing.Size(230, 626);

            this.dgvRecordings.Style.CurrentCellStyle.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(166)))), ((int)(((byte)(216)))), ((int)(((byte)(255)))));

            this.dgvRecordings.Style.CurrentCellStyle.BorderThickness = Syncfusion.WinForms.DataGrid.Styles.GridBorderWeight.Thin;

            this.dgvRecordings.TabIndex = 0;

            this.dgvRecordings.Text = "dgvRecordings";

            this.dgvRecordings.QueryCellStyle += new Syncfusion.WinForms.DataGrid.Events.QueryCellStyleEventHandler(this.dgvRecordings_QueryCellStyle);

            this.dgvRecordings.SelectionChanged += new Syncfusion.WinForms.DataGrid.Events.SelectionChangedEventHandler(this.dgvRecordings_SelectionChanged);

It sometimes throw the error as follows

EventProcedureView: bwPatientData_RunWorkerCompleted(), "System.ArgumentNullException: Value cannot be null. Parameter name: source at System.Linq.Enumerable.Where[TSource](IEnumerable`1 source, Func`2 predicate) at Syncfusion.WinForms.DataGrid.SfDataGrid.RefreshViewAndContainer(Object oldValue, Object newValue) at Syncfusion.WinForms.DataGrid.SfDataGrid.<>c__DisplayClass79.<OnDataSourceChanged>b__78() at Syncfusion.WinForms.DataGrid.BusyIndicatorHelper.RunWork(SfDataGrid dataGrid, Action work, BusyIndicatorAction busyIndicatorAction, Boolean showBusyIndicator) at Syncfusion.WinForms.DataGrid.SfDataGrid.OnDataSourceChanged(Object oldValue, Object newValue) at Syncfusion.WinForms.DataGrid.SfDataGrid.set_DataSource(Object value) at BeaconEarrs.EventProcedureView.LoadRecordingGrid(List`1 recordingData) at BeaconEarrs.EventProcedureView.bwPatientData_RunWorkerCompleted(Object sender, RunWorkerCompletedEventArgs e)"

Since this error is not consistently happening, I don't have a trace of the issue.

Do you know why this is happening or any root cause of this issue ?

Can you please help ?

Thanks
