am just wondering. How one earth can this be an "Object reference not set to an instance of an object"
The line that says "foreach (TableRow itemsTableRow in itemsTable.Rows)" is throwing that damn error. I think the TableRow is instantiated on every round of the foreach loop
try
{
if (null == Page.Session["ILSPrintJobObject"])
throw new ApplicationException(TextHelper.Get("IlsControls_PrintItemPrint_PrintButtonClick_InvalidPrintJobException"));
var printJob = (PrintJob)Page.Session["ILSPrintJobObject"];
// Printer or PrinterElux
var printer = new Printer((int)printJob.PartId);
//string fileName = ILSBase.Instruction.GetAttachedInstruction(printJob);
var fileName = InstructionImageLocation(printJob);
var hasInstructionFile = !string.IsNullOrEmpty(fileName);
mainPage = Parent.Parent;
itemsTable = (Table)mainPage.FindControl("printSelectPlaceHolder")
.Controls[0].FindControl("itemPlaceHolder")
.FindControl("itemsTable");
var itemIdsAndQuantitiesList = new List<ItemsQuantities>();
foreach (TableRow itemsTableRow in itemsTable.Rows)
{
if (itemsTable.Rows.GetRowIndex(itemsTableRow) == 0) continue;
string currentItemQty = null, currentItemId = null;
foreach (TableCell cell in itemsTableRow.Cells)
{
if (itemsTableRow.Cells.GetCellIndex(cell) == 0)
currentItemQty = ((TextBox)cell.Controls[0]).Text;
else if (itemsTableRow.Cells.GetCellIndex(cell) == 1)
currentItemId = cell.Text;
}
itemIdsAndQuantitiesList.Add(new ItemsQuantities
{
ItemID = currentItemId,
Qty = currentItemQty
});
}
printJob.ItemsAllQty = itemIdsAndQuantitiesList.Where(x => x.Qty.Trim().Equals("0")).ToList();
Page.Session["ILSPrintJobObject"] = printJob;
string sFile = string.Join(",", printer.GeneratePrintFile(printJob).ToArray());
string jsCommand = printer.GeneratePrintCommand(userName, sFile, printJob.Label, printJob.Workstation);
Page.ClientScript.RegisterStartupScript(GetType(), "PrintScript", jsCommand, false);
// Aplication instruction?
if (hasInstructionFile)
{
string url = "/" + ILSConfig.AppName + "/request/Instruction.aspx";
//string script = "DisplayApplicationInstruction('" + url + "', 500, 200);";
string script = "$('#overlay-image-location').attr('src', '" + fileName + "');";
if (hasInstructionFile) script += "\nshowPopup();\n";
Page.ClientScript.RegisterStartupScript(this.GetType(), "ApplicationScript", script, true);
}
}
catch (Exception exp)
{
Logger.RecordMessage(exp.Message, ILSBase.Log.LogLevels.Error);
OnError(exp);
}
