How can I insert an element to the bottom of a specific page in iText7?

I'm exploring different options for .NET PDF libraries. One of my requirements is to place a box at the bottom of the first page and if any of the content reaches the box, it should overflow onto the next page.
For example:
Shown above, paragraph 7 would normally take up some of the space that's occupied by the "reserved" area. Instead, the part that would have taken up that space is shifted to the next page.
That image was achieved using Gembox.Document by adding the box as a footer element that only renders on the first page. However, in iText7, the examples I've seen for adding a footer (such as this one), places the content as a floating element that renders over the existing content and does not affect the layout/flow of the rest of the document.
I also tried adding a paragraph on the PageEnd event handler without the canvas (snippet below), but instead of adding it to the specified page, it's added to the end of the entire document.
public void HandleEvent(Event evt)
{
var docEvent = (PdfDocumentEvent)evt;
var page = docEvent.GetPage();
int pageNum = docEvent.GetDocument().GetPageNumber(page);
if (pageNum == 1)
{
doc.Add(new Paragraph("Testing a thing"));
}
}
Is the type of effect I'm looking for something that I can replicate using iText7?

I believe you can combine the concepts of https://github.com/itext/i7ns-samples/blob/develop/itext/itext.samples/itext/samples/sandbox/acroforms/AddExtraTable.cs and https://github.com/itext/i7ns-samples/blob/develop/itext/itext.samples/itext/samples/sandbox/events/TextFooter.cs to achieve what you need.
The idea is as follows:
reserve place for your box by making iText give the document's renderer less space for the first page
fill this box with a help of iText's end page events
Another option was suggested in How can I insert an element to the bottom of a specific page in iText7? : you can temporary call Document#setBottomMargin , since elements added via Document#add will not be placed on margins. Then, once the first page is layouted, you can set the initial margins again. This option, however, requires understanding of you layout flow, since the margins should be set only after the content of the first page is layouted.
One more suggestion: althouth event functionality is rather flexible and useful, it seems like using a sledgehammer to crack a nut. You need to call Canvas#ShowTextAligned, which could be done without any event handling. So ideally I would prefer to do the following:
handle page's layout area via an extension of DocumentRenderer
Calling Canvas#ShowTextAligned to fill the reserved box.

As you said, you are exploring different .NET PDF libraries. So I would advise PDFFlow library, which does exactly what you need.
If you have a footer, main document flow will take the rest of page area and will be automatically continued at the next page without overlaying footer.
DocumentBuilder.New()
.AddSection()
.AddParagraph("long text")
.ToSection()
.AddFooterToBothPages(40)
.AddParagraph("this a footer set for each page of this section")
.ToDocument()
.Build("result.pdf");
Here is a tutorial with code examples of using headers, footers, left/right repeating areas: AddingRepeatingArea tutorial.
Hope, this will help you :)

C# Winforms Help Text Change font

I have a little help pop-up that displays some text when the user presses a "?" label next to a drop-down to explain the different selections.
I did it using the Help.ShowPopup command since that seemed the easiest.
I was hoping there was a way to add different font properties to parts of the text or at least to the whole thing without having to go the direction of a CHM/HTML help-file.
Here is what I am trying to do:
private void helpLbl_Click(object sender, EventArgs e)
{
// for some reason, it ignores the 'parent' parameter
// and lays it out on the screen's coordinates
Point helpLocation = helpLbl.PointToScreen(Point.Empty);
helpLocation.Y += helpLbl.Height; // have it display underneath the control
Help.ShowPopup(this, // hosting form
#"<b>Fixed:</b>
Removes a fixed amount from the sale
<b>Percent Value:</b>
Removes a set percentage of the selected package from the sale
...", helpLocation);
I was hoping since there's the option to use an HTML document to display the help, I could use HTML tags to format what was being displayed, but it doesn't appear so. Any ideas?
Is there a way to do something like displaying a RichTextBox in the help pop-up?
Another possibility is generating a HTML document on-the-fly, but it asks for a "url" if I'm not supplying the text directly and I think that might be a little over-kill for the small amount I'm trying to do here.

You have two options. One is to use a WebBrowser Control. This natively accepts HTML and displays it. The problem with it is its kind of bloated just to use as a simple label.
Your second option is to simply create a RichTextLabel, simply like this:
public class RichTextLabel : RichTextBox
{
public RichTextLabel()
{
BorderStyle = BorderStyle.None;
}
}
Add this to your form and set the Rtf property to your RTF code. You will have to convert your HTML to RTF, which is easy if you got a program such as Microsoft Word, for example.

Printing Grid Control with multiple elements

I am trying to print a grid control with multiple elements in it.
I am doing this,
PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == true)
{
printDialog.PrintVisual(gridReport, "Visit Report");
}
gridReport is my grid name.
As my grid contains a lot of child elements, only a part of it is getting printed and rest is getting chopped.
How should i solve this ?

I had the same problem a month ago. As far as i know .Net print dialog only prints one page and cuts everything beyond that page. If you want to print multi pages you have to write some logic yourself.
I created a bmp file and cut it to multiple pages, added the pages to a list and at the end printed the list of pages.
I found this article very helpful (it has a solution that cuts the bmpwhenever the height of one page is exceeded, so you will also have to implement a similar logic to cut your bmp when the width of a page is exceeded)

i hope this will help.

Android Webview equivalent in Windows Phone 8 app

I have text with some HTML tags in it.
Example : <I> I Play Football and Cricket </I>
Now when i try to display this text in Textblock it displays with Italics tag <I> as well.
The data is present in the XML file and i am working on Windows Phone 8 application.
In Android we use Webview, but what do i need to use here ?
EDIT
I have tried using TextBlock with inlines:
Italic itlText = new Italic();
itlText.Inlines.Add(new Run() { Text = "This is some example text in italics" });
Inilinetext.Inlines.Add(itlText);
It works good But issue here is suppose i have a text like below.
"This is text in <I>Italics</I> here"
Now it display entire text in italics.

This depends on how much content you want to display. If you will show large amount of HTML text, use WebBrowser control for that.
In case you only have a couple of tags i, em, b or strong, then you can actually use TextBlock, but you would have to do the parsing yourself then in order to convert the HTML to the suitable XAML components.
You also have to ask yourself how many such controls you need to display on a single page. If the answer is a few, use the WebBrowser then. If you need to display lots of them, say you have a chat or a feed, then the second route would be better.
EDIT:
Use the following code:
Inilinetext.Inlines.Add(new Run() { Text = "This is text in " });
Inilinetext.Inlines.Add(new Run() { Text = "Italics", FontStyle = FontStyle.Italic });
Inilinetext.Inlines.Add(new Run() { Text = " here" });
I told you you have to parse the original string to see which parts are italic and which are not.

ItextSharp fit text to a page

i'm italian and i'm sorry for my english.
I'm trying to use itextSharp to convert a txt file into pdf file.
this is my code:
String l = file.ReadLine() + "\r\n";
while (l != null)
{
iTextSharp.text.Font contentFont = iTextSharp.text.FontFactory.GetFont("Arial", 8, iTextSharp.text.Font.NORMAL);
//Chunk line = new Chunk(l, contentFont);
Paragraph p2 = new Paragraph(l,contentFont);
oDoc.Add(p2);
oDoc.Add(Chunk.NEWLINE);
l = file.ReadLine();
}
oDoc.Close();
The text page is a multi page file, so I would like to reproduce the same on the pdf file.
When i read "Page 2" on my txt file, I need to create a new page in the pdf file.
I would like to put all the text before page 2 in only one pdf page.
How can i fit all the text in only one pdf page?
Thank's so much and sorry for my english

Well, if you reach the end of a text page before the end of a PDF page, you can just call oDoc.newPage(). The alternative isn't so simple.
The only Easy Way To Do It would be to create a text field on each page, with the multiline flag set. You then set the font size to zero and the field will automatically pick a font size that will size the font to fit the available space (within some reasonable limits).
You could also use a ColumnText and call go(true). This will "simulate" layout allowing you to make adjustments to the actual font size prior to actually drawing the text to a content stream.
