Dynamically updating datagrid control results in cross-thread operation error

Hi all,

I am writing a piece of code which will simply receive the data in UART(serial port) and populate the same in the Datagrid control. whenever it receives the data, it has to add a new row in the DataGrid control.

But when i tried writing the code it throwed me a error which i couldn't resolve and when i googled everyone talks about threading concept for this issue, which i am not aware or could not understand.

Error: "An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll
Additional information: Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on."

code snippet is attached for reference

 
DALIComm - Instance of Serialport
DALIDataGrid - Instance of Datagrid

        private void DALIComm_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            // Process received data
            byte[] buffer = new byte[2];//DALIComm.BytesToRead];
            int bytesRead = DALIComm.Read(buffer, 0, buffer.Length);
            strNewRowData[4] = Convert.ToBase64String(buffer);
            bUpdateDataGrid = true;
            AddNewRow();
        }

        public void AddNewRow()
        {
            if(bUpdateDataGrid)
            {
                DateTime TempData;
                long DeltaTime;
                gu32SerialNumber++;
                strNewRowData[0] = gu32SerialNumber.ToString();
                strNewRowData[1] = System.DateTime.Now.ToShortDateString();
                TempData = System.DateTime.Now;
                TimeSpan span = TempData.Subtract(Convert.ToDateTime(strNewRowData[2]));
                DeltaTime = (long)span.TotalMilliseconds;
                strNewRowData[3] = Convert.ToString(DeltaTime);
                strNewRowData[2] = TempData.ToString("hh:mm:ss.fff tt");
                strNewRowData[5] = "1";
                DALIDataGrid.Rows.Add(strNewRowData);
                bUpdateDataGrid = false;
            }
        }


Error on the line which is highlighted in bold and size-4.

Is there a simply to fix this issue? Thank you very much in advance.
