I m doing a project to export the data from Gridview to PDF. Everything was fine and a new pdf document has been opened whenever I click the PDF image but there was no records displayed in it.
I have 15 records in Gridview and those records have displayed using Table Adapter. I used the Sand and Sky Auto Formatting option in Gridview and color, tablecell width, 15 rows are displayed perfectly in PDF without the text. what am I missing.

I am running into a problem with the btnPdf.on pdfDoc.Close it gives me an IOException was unhandled by user code.. The detail is The document has no pages.. I have a populated grid.. The only changes I made were to change the filename to filename LotGrid.pdf and the grid name to the name of my gridview..
View 1 RepliesI'm trying to export my gridview to pdf but the html parsing of the iTextSharp control seems to be failing. I have to create an HtmlForm like below and add the gridview to it because the code is in a custom control, so I cant pass the gridview directly. I get an error saying "gridview must be in a form tag with runat=server"
If I don't insert the test header like i do below, I get an error saying "document has no pages"
At the moment the pdf is generated but it only has the text "testing".
The htmlform html doesn't get parsed i think. Here is a small portion of what the newHtml variable below contains when I create it.

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;"); gridview.HeaderRow.Style.Add("font-size","7.20px"); gridview.HeaderRow.Style.Add("color","#284775");
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");
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);

View 1 RepliesI 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 had to integrate the GridView to a form that is created at runtime because I said I should be in one, but even so when I export the file I get blank, really I do not know what I'm doing wrong and I have many controls that I have to export.
I am using ITextSharp to create a pdf. But when I am binding data to Gridview dynamically which was actually a result of ajax webmethod, its showing a blank PDF file.

View 1 RepliesIt is possible to create a PDF document in memory with iTextSharp that gives the user a choice to "open" or "save"?, and if it opens then it opens in a browser window.
At the moment the only I have save it to disk.
EDIT:
ok I've got it sussed. I did end up having to write the file to a folder, but it is only temporary as gets overwritten every time. Here is the solution for what it's worth:
private void GeneratePDF() {
var doc1 = new Document();
string path = Server.MapPath("~/pdfs/");
string filepath = path + "Doc1.pdf";
PdfWriter.GetInstance(doc1, new FileStream(filepath, FileMode.Create));

I'm working on dynamically filling in the fields on a pdf document using ITextSharp. I'd like to be able to determine the "export value" of the checkbox is from the codebehind in order to determine what value to send to this checkbox if it should be checked. Most of the documents I've worked with in the past had the same export value for every check box but the one I'm currently working with varies from checkbox to checkbox. I could go through all of the text boxes and make them consistent but it would save a lot of time in the future if I could just determine what the export value of these checkboxes are at runtime and set them accordingly.I tried to implement the solution below in C# and ended up with the following code:
public string GetCheckBoxExportValue(AcroFields pdfDocument, string checkBoxFieldName)
{
AcroFields.Item item = pdfDocument.GetFieldItem(checkBoxFieldName);

i am failing to get the Base64 string and show it as an image in the output pdf file.
I have a signautre canvas that saves the output directly into the sql database.
I need to be able to export PDF's that I am creating to JPEG, so that users can have a screenshot/thumbnail of the end product, which is faster than opening the whole PDF.
I am running this on an ASP.NET website running in Medium Trust in the Rackspace Mosso Cloud.
I have yet to find a library that will either work in Medium trust, or in the case of ABC PDF, which works great locally, wont load in Mosso. Maybe Mosso has a custom trust level?
I know that iTextSharp works on Mosso, but I haven't been able to figure how to "screenshot" a single page of a PDF, or export a page to JPEG.
How do i export multiple charts to pdf using iText library?
