Replace Multiple Different Images On One PDF Template Page With Itext (itextsharp)
Nov 29, 2010
We have an ASP.NET application that users use to generate certain reports. So far we had one PDF template that had one image on it, and we would just replace that image with our programatically generated one (graph). We have used code from this site for that: [URL] Problem now is that we have two different images on one PDF page, and the code from link above selects both images on one page and replaces them all at once with our generated image. how to replace multiple different images on one page with itext?

My website use master page as template. All my other pages spread in different level folder. Master page will get images (which use related path - related to master page) from style sheet file which located in App_themds's sub folder. When application run,The page will lost all images if the content page did not located in the same level as Master page.

Before converting a gridview to PDF I can modify the font size and color using:
gridview.HeaderRow.Style.Add("font-family","Arial, Helvetica, sans-serif;");Â gridview.HeaderRow.Style.Add("font-size","7.20px");Â gridview.HeaderRow.Style.Add("color","#284775");Â
gridview.Style.Add("font-family","Arial, Helvetica, sans-serif;");
gridview.Style.Add("font-size","6px");
The gridview has different column widths because of the information that is being displayed, those sizes are set .aspx file. But, the generated pdf file auto adjusts the width of each column to be the same size, therefore the information is shrinked and doesnt look good..
I tried the following:
gridview.Width =100;
or
gridview.Style.Add("width","100");Â
or
gridview.Columns[3].ItemStyle.Width =Unit.Pixel(10);
And many more but haven't been able to adjust the gridview to it's original columns width. How can I do that?
This is the code I use to generate the PDF file:
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);

I am using the iTextSharp library to export a gridview with images to pdf. Some of the image urls are not directly to an image, but rather direct you to a .aspx page which displays the image. (includes a parameter with the id, and when you view the url in a browser you can see the image.) When I run the below code, I get an error that the image url in not a recognized image format.
Code:
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);

I have a template where I want to replace certain regions. In my example below, I want to extract the regions between the. comments, manipulate it, then replace them back after the manipulation. I do not need the logic to merge the fields, but I need to extract the regions so I can use my logic and place it back into the template. Does anyone know of an elegant or simple way to extract these regions? I am also hoping to extract the url values in the process as well if it is easy to do along the way.

I want to change the way my blogs are displayed on my website. I currently use a seperate table in SQL to hold them and do a loop and replace.
All I really need to do is have a code that can be translated into real HTML in the blog code. I need to know the image name and the css class.
I was thinking is it possible to have somthing like this in a blog stored in the DB
<img L 1234.jpg> and use regex to match it and change it ton<img src="1234.jpg class="imgleft">
I know it looks like well why not just use the long code and not use regex, but I have a method that gets in the image path from the image name with padding. So in this case the image path would be 000/000/001/234/1234.jpg
I would have more then one occurance in the original string so would need to either somehow replace them all at once or use the regex to loop through untle they have all be matched
is something like this possible or do I need a different approach

1: I have a .html file that has some markup with some placeholder tags.
[code]...
4: PersonInfo.aspx is literally empty since I am injecting html from code-behind.
When the PersonInfo.aspx is called the html-template markup with appropriate values in the placeholder will be displayed. Also there are chances I would like to send the final markup in an html email (though that is not part of the question as I know how to email).
Is this the best way to fill values in my html-template or is the any other better alternative?
Note: This is a very simple sample example. My class is very complex involving objects as properties and also my html template have 40-50 placeholders.
So code in my step 3 will need 40-50 Replace statements.

i am creating a page that will display multiple images from the database. i can do it if i will only display one image, by using a page to be rendered as image. something like this...
using (SqlDataReader reader = comm.ExecuteReader())
{
Byte[] images = new Byte[]();
while (reader.Read())
{
Response.BinaryWrite(images);
}
}

I am relatively new to asp.net and program using VB. I have written the following code to try and replace ReadOnly CheckBoxes with an image as the CheckBoxes appear grayed out and difficult to see. The GridView is linked to a SQL DataSource to display information only.
The problem I am having is displaying the image for unchecked boxes where the data (PET) in the SQL table is set to 'false'. The code displays the checkbox image fine when the bit is set to 'true', but no image appears in the GridView rows where the bit is 'false'.

I'm using the iText library for .NET to generate a PDF. I need to output a PDF with an image, which has three text strings positions centered vertically, but absolute Y positions. Each string uses a different font. I've been struggling for hours to find a way to do this, I can get the first line on Ok using SetSimpleColumn(), but further attempts have been fruitless.

On my page I have textbox in which user enters value. When 3 values are entered the autocomplete panel shows.In the panel the names and surnames of all available people are shown bassed on the value user enters. Bellow each name and surname is picture of each "candidate". However images are stored on another server (using https "protection") and some people don't have picture.

I've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.
