I have this code that allows users to lookup batch IDs. If the user enters HM and clicks the lookup button, it goes to the first record that begins with HM. However, if the user enters only H and clicks the lookup button it does not go to the first record beginning with H. I do not see why. Batch ID is the first column in the SQL query and is the search column.

        public frmLookupBatch(string BatchID)
            StartPosition = FormStartPosition.Manual;
            Location = new Point(500, 40);
            batchID = BatchID;

                ActiveControl = dgvBatches;

                //Make sure no cells are selected

                if (!string.IsNullOrEmpty(BatchID))
                    //Search data grid for batch ID (contains)
                    rowIndex = dgvBatches.Rows.Cast<DataGridViewRow>().Where(r => r.Cells["Batch ID"].Value.ToString().Contains(BatchID)).First().Index;

                    if (rowIndex >= 0)
                        //Select cell in the selected row
                        dgvBatches.CurrentCell = dgvBatches[0, rowIndex];

                        //Scroll to row of selected cell
                        dgvBatches.FirstDisplayedScrollingRowIndex = rowIndex;
                        //Batch ID contains match not found
                        MessageBox.Show("No such batch ID found : " + batchID);
                    //Batch ID not supplied
                    MessageBox.Show("No batch ID specified");
            catch (Exception ex)
                string eMsg = "Lookup Transfer-001A: ERROR: " + ex.Message;
                if (Model.StackTraceWanted) eMsg += "\n" + ex.StackTrace;
                if (Model.StackTraceWanted) MessageBox.Show(eMsg);
