Calling a field and replace

[neo_xaml]

I am trying to call/isolate the field InspectionSummary.InspectionSummaryDate so I can do a Replace on it. Basically replace all "-" with "/".

I can't seem to be able to do a Replace from the SQL. I am wondering how in Section #1 or #2 I could
reformat the field value before it appears in the StackPanel.

#1

private void FillDataGrid()
        {
            ArrayList permitTypes = new ArrayList();
            permitTypes = control.GetSummaryTypes(currentJobID);
            if (permitTypes.Count > 0)
            {
                for (int i = 0; i < permitTypes.Count; i++)
                {
                    //Get the summaries for each type
                    DataView dv = control.GetSummary(currentJobID, permitTypes[i].ToString());
                    
                    //Check to see if there are rows and if so add the Panel
                    if (dv.Table.Rows.Count > 0)
                    {
                        Expander ex1 = new Expander();
                        ex1.Header = permitTypes[i].ToString();
                        DataGrid dgList = new DataGrid();

                        ex1.Content = dgList;
                        dgList.ItemsSource = dv;

                        b8Panel.Children.Add(ex1);
                        //Draw a line between each card dropdown expander panel
                        Line line = new Line();
                        line.X1 = 0;
                        line.X2 = ex1.ActualWidth - 1;
                        line.Y1 = 0;
                        line.Y2 = ex1.ActualHeight - 1;
                        line.Stroke = Brushes.Black ;
                        line.StrokeThickness = 2; 
                        b8Panel.Children.Add(line);
                        
                    }
                }
            }
            
        }

#2

public DataView GetSummary(int jobID, string permitType){
            //Set the DBCommand object
            DataSet jobDataSet = null;
            IDataParameter[] paramCollection = new IDataParameter[2];
            OleDbParameter p_JobID = new OleDbParameter("JobID", jobID);
            paramCollection[0] = p_JobID;

            OleDbParameter p_permitType = new OleDbParameter("PermitType", permitType);
            paramCollection[1] = p_permitType;

            jobDataSet = db.ExecuteDataSet(GET_SUMMARY_LIST, CommandType.Text, paramCollection);
            return jobDataSet.Tables[0].DefaultView;

		}

#3

  const string GET_SUMMARY_LIST = "SELECT InspectionSummary.InspectionType, InspectionSummary.Status,  " +
"InspectionSummary.Inspector,  left(InspectionSummary.InspectionSummaryDate,10) as  Dates " +  
"FROM InspectionType INNER JOIN InspectionSummary ON InspectionType.InspectionTypeName = InspectionSummary.InspectionType"  + 
"WHERE InspectionSummary.JobID=@JobID AND InspectionSummary.PermitType=@PermitType ORDER BY InspectionSummary.InspectionSummaryDate;";
