Web Forms :: Export Panel With GridView DropDownList To PDF Using ITextSharp
May 11, 2012
I have a question on the subject to export the contents of a panel to pdf, can export the panel even if it has some controls such as GridView, DropDownList, etc.? I have the following code:
protected void btnExport_Click (object sender, EventArgs e) {
Response.ContentType = "application / pdf";
Response.AddHeader ("content-disposition", "attachment; Panel.pdf filename =");
HtmlForm HtmlForm form_nuevo = new ();
form_nuevo.Attributes.Add ("runat", "Server");
form_nuevo.Controls.Add (GridView1);
[Code] ....
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'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);

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'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 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.

I have implemented excellent code for saving Gridview to Excel, CSV, Word.
I also have a Dropdown control that filters rows by selected values in a specific column, and then only rows with the selected values are displayed in the Gridview.
However when saving to Excel and other formats, all rows are saved, not just the selected ones. Is there a method to filter the Gridview by dropdown selection and be able to save only selected rows?
