I am trying to make CoilDetails bold and center alligned. How do I do that in the current context. Please help

Use p.SetTextAlignment(iText.Layout.Properties.TextAlignment.CENTER); for aligning it in center and for setting it to bold after add try using .SetBold() or .SetFont(bold)

I do a few scripts w/ itext7 using linqpad.net in c#
but I've no issues to convert to visual studio.
here's a line in C#
p = new Paragraph(targetText).SetFontSize(12).SetTextAlignment(TextAlignment.JUSTIFIED).SetFontColor(new DeviceRgb(0, 153, 0)).SetBold();

how to create dynamic Required field Validator

I have generated an array of required field validators using following code:
Panel[] divMain = new Panel[22];
DropDownList[] gender = new DropDownList[22];
TextBox[] txtFirstName = new TextBox[22];
TextBox[] txtMiddleName = new TextBox[22];
TextBox[] txtLastName = new TextBox[22];
TextBox[] txtAge = new TextBox[22];
RequiredFieldValidator[] req = new RequiredFieldValidator[30];
and i am creating some dynamic controls using following code:
for (int i = 0; i < noOfad - 1; i++)
{
HtmlGenericControl p = new HtmlGenericControl("p");
HtmlGenericControl strong = new HtmlGenericControl("strong");
strong.InnerText = "Adult" + Convert.ToString(i + 2);
p.Controls.Add(strong);
divAdultMoreForm.Controls.Add(p);
Panel div = new Panel();
HtmlGenericControl p1 = new HtmlGenericControl("p");
p1.InnerHtml = "<span><strong>Full Name (As per Valid Govt Id Proof valid )</strong></span> <span><strong style=' margin-left: 549px;'>Age(in Years 18 +) </strong></span>";
div.Controls.Add(p1);
HtmlGenericControl p2 = new HtmlGenericControl("p");
gender[i] = new DropDownList();
gender[i].Items.Add(new ListItem("Title", "0"));
gender[i].Items.Add(new ListItem("Mr.", "1"));
gender[i].Items.Add(new ListItem("Mrs.", "2"));
gender[i].Items.Add(new ListItem("Ms.", "3"));
gender[i].CssClass = "txt";
p2.Controls.Add(gender[i]);
txtFirstName[i] = new TextBox();
txtFirstName[i].Attributes.Add("placeholder", "First Name");
txtFirstName[i].CssClass = "txt input";
txtFirstName[i].ID = "txtFirstName" + Convert.ToString(i);
req[i].ControlToValidate = txtFirstName[i].ID;//Object refrence not set to an instance ofo an object
req[i].ForeColor = System.Drawing.Color.Red;
req[i].ErrorMessage = "*";
txtFirstName[i].CssClass = "input txt";
txtMiddleName[i] = new TextBox();
txtMiddleName[i].Attributes.Add("placeholder", "Middle Name");
txtMiddleName[i].CssClass = "txt input";
txtMiddleName[i].CssClass = "input txt";
txtMiddleName[i].ID = "txtMiddleName" + Convert.ToString(i);
txtLastName[i] = new TextBox();
txtLastName[i].Attributes.Add("placeholder", "Last Name");
txtLastName[i].CssClass = "txt input";
txtLastName[i].CssClass = "input txt";
txtLastName[i].ID = "txtLastName" + Convert.ToString(i);
txtAge[i] = new TextBox();
txtAge[i].Attributes.Add("placeholder", "Enter Age");
txtAge[i].CssClass = "txt";
p2.Controls.Add(txtFirstName[i]);
p2.Controls.Add(txtMiddleName[i]);
p2.Controls.Add(txtLastName[i]);
p2.Controls.Add(txtAge[i]);
div.Controls.Add(p2);
divAdultMoreForm.Controls.Add(div);
}
But when i am assigning the control to validate to the validator req[i] then there comes an error Object reference not set to an instance of an object.
Can not understand why this problem is occuring.
Any help to correct my code!
Thanks

This is due to the fact that you forgot to initialize the RequiredFieldValidator array object. This seems to be missing from your code :
req[i] = new RequiredFieldValidator();
After this you can play with its properties.
Hope this clears it.

How to apply a different text for each image?

I have this looping intruction (foreach) which reads every image from the "GalleryImages" folder. What I want is to apply a different text for each image. Do I do this with the foreach instruction as well? Do I create a folder where I plce more .txt files?
var files = Directory.GetFiles(#".\GalleryImages");
string text22 = System.IO.File.ReadAllText(#"C:\Users\Public\TestFolder\WriteText.txt");
foreach (var file in files)
{
foreach ()
{
FileInfo fileInfo = new FileInfo(file);
WineModel wineModel = new WineModel();
wineModel.Image = new Uri(file, UriKind.Relative);
wineModel.Description = text22 + "text text text text text text text text text text text" +
Environment.NewLine + "text text text text text text text text text text text";
wineModel.Price = new Random().NextDouble();
BitmapImage bi = new BitmapImage();
bi.BeginInit();
bi.UriSource = wineModel.Image;
bi.EndInit();
var button = new KinectTileButton
{
Label = System.IO.Path.GetFileNameWithoutExtension(file),
Background = new ImageBrush(bi),
Tag = wineModel
};
this.wrapPanel.Children.Add(button);
}
}
I've also posted the code for the click event :
private void KinectTileButtonClick(object sender, RoutedEventArgs e)
{
var button = (KinectTileButton)e.Source;
var wineModel = button.Tag as WineModel;
var selectionDisplay = new SelectionDisplay(wineModel);
this.kinectRegionGrid.Children.Add(selectionDisplay);
e.Handled = true;
}

Download multiple pdf documents using itextsharp

i have a tree view in which there are certain set of document list and another grid having patient details. what i need to do is when we select docs from treeview (select multiple..checkbox enabled) and patients from grid and click on a button should create all the documents using ITEXTSHARP.that is multiple documents are created. I tried it like this,
on button click
foreach( TreeNode node in TreeView1.Nodes)
{
if (node.ChildNodes.Count>0)
{
for(int i=0 ;i<(node.ChildNodes.Count);i++)
{
if (node.ChildNodes[i].Checked==true)
{
string nodevalue = node.ChildNodes[i].Value.ToString();
if (nodevalue=="3")
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chk = row.FindControl("CheckBox1") as CheckBox;
if (chk.Checked)
{
Label lbl_name = row.FindControl("Label1") as Label;
Label lbl_dob = row.FindControl("Label3") as Label;
pdf_abcd(lbl_name.Text.Trim(), lbl_dob.Text.Trim());
}
}
}
}
}
}

but the system only down loads one doc..can anyone helpme

If you step back and ignore PDFs for a bit and concentrate on just HTTP requests and responses you should have your answer. When a browser makes an HTTP request (your button click) the server is allowed to send one and only one response. You're code is trying (unsuccessfully) to send multiple responses to the browser. The first time that Response.End is called the pipeline gets terminated actually and the rest of your code doesn't run.
The solution is to just make one giant PDF in one pass, make individual PDFs and merge them or create a zip file containing all of the PDFs.

I guess you should create a zip file that combines your PDF files

If you want to Open the file in new tab you have different Methods:
Method 1:
Response.Clear();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=foo.pdf");
Response.TransmitFile(filePath);
Response.End();
Method 2:
Process process = new Process();
process.StartInfo.UseShellExecute = true;
process.StartInfo.FileName = outputPdfFile;
process.Start();
Hope this helps you!

How to get rid of my "After Spacing" on open xml

In open XML my word document defaults to having "Spacing After: 10 pt" How would I change it to 0, so there is no spacing.
Here is my code, which pretty much grabs the information from a database and places it onto a word document to be able to print out. But the spacing is making the document too big.
using (WordprocessingDocument wordDoc = WordprocessingDocument.Create(filepath, WordprocessingDocumentType.Document)) {
MainDocumentPart mainPart = wordDoc.AddMainDocumentPart();
mainPart.Document = new Document();
Body body = mainPart.Document.AppendChild(new Body());
Paragraph para_main = body.AppendChild(new Paragraph());
Run run_main = para_main.AppendChild(new Run());
// Goes through all of the forms
foreach (var form in forms) {
Table table = new Table();
// Initialize all of the table properties
TableProperties tblProp = new TableProperties(
new TableBorders(
new TopBorder() { Val = new EnumValue<BorderValues>(BorderValues.BasicBlackSquares), Size = 16 },
new LeftBorder() { Val = new EnumValue<BorderValues>(BorderValues.BasicBlackSquares), Size = 16 },
new RightBorder() { Val = new EnumValue<BorderValues>(BorderValues.BasicBlackSquares), Size = 16 },
new BottomBorder() { Val = new EnumValue<BorderValues>(BorderValues.BasicBlackSquares), Size = 16 },
new InsideHorizontalBorder() { Val = new EnumValue<BorderValues>(BorderValues.BasicBlackSquares), Size = 8 },
new InsideVerticalBorder() { Val = new EnumValue<BorderValues>(BorderValues.BasicBlackSquares), Size = 8 }
),
new SpacingBetweenLines() { Before = "20", After = "20" }
//new TableCellProperties(
// new
//new TableJustification() {Val = TableRowAlignmentValues.Center}
);
table.AppendChild<TableProperties>(tblProp);
Paragraph para_header = body.AppendChild(new Paragraph());
Run run_header = para_header.AppendChild(new Run());
RunProperties runProps = run_header.AppendChild(new RunProperties(new Bold()));
string username = form.Username;
string proces_header = form.HeaderTitle;
run_header.AppendChild(new Text(proces_header + " | " + username));
for (int i = 0; i < form.FieldList.Count; i++) {
if (!(form.FieldList[i].Token == "USR" || form.FieldList[i].Token == "SNT")) {
TableRow tr = new TableRow();
TableCell header_cell = new TableCell();
header_cell.Append(new Paragraph(new Run(new Text(form.FieldList[i].Label))));
TableCell value_cell = new TableCell();
value_cell.Append(new Paragraph(new Run(new Text(form.FieldList[i].Value))));
tr.Append(header_cell, value_cell);
table.Append(tr);
}
}
wordDoc.MainDocumentPart.Document.Body.Append(table);
}
mainPart.Document.Save();
wordDoc.Close();
return "Success";
}

The line spacing needs to be appended to the paragraph properties and of course that needs to be appended to the paragraph.
Here is the long way to do it. The SpacingBetweenLines can also set the line height and the "rules" control how the before and after values are used.
SpacingBetweenLines spacing = new SpacingBetweenLines() { Line = "240", LineRule = LineSpacingRuleValues.Auto, Before = "0", After = "0" };
ParagraphProperties paragraphProperties = new ParagraphProperties();
Paragraph paragraph = new Paragraph();
paragraphProperties.Append(spacing);
paragraph.Append(paragraphProperties);
It looks like you are trying to set the line spacing to the table. That will not work that way(believe me I tried). Text around the table is controlled by the text wrapping and the positioning of the table.
Also when working with multiple tables, if you want to keep them separated there needs to be a paragraph(or something other then a table) after the table, otherwise your tables we merge together.
If you need that space create a paragraph with the font set to .5 or something really small and just add it after each table.
