Convert A Gridview Templatefield To Pdf ITextSharp
Jun 22, 2012
I have a GridView which is programatically filled from the DB (not a SqlDataSource or such). There are 4 columns which are TemplateFields as I format their text. They are Dates and Times and this is the one of their TemplateField:[code]'ve been using the method in this Post which was converted to VB code from this to convert the GridView to a PDF using iTextSharp.My issue is that I'm getting a Null Reference exception here when adding the GridView data to the PDF(inside the For Loops):[code]These Date/Time columns show up as empty on the PDF while all other columns show up with no issues.

I have a gridview which I'm converting to a PDF with iTextSharp. I've been following along with the method in this post.Since I'm using VB.net I've changed all the C# code over but I've been having problems with one line.if (gvReport.Columns[columnNo] is TemplateField)I don't know how to write this line in VB.net and as I have a few templatefields in my gridview (for formatting) they show up as blank in the PDF

I am creating a web application in ASP.net/VB.NET and I have an issue with the gridview.Currently, I have the gridview populated with data from the DB and I've also coded the update button to allow the user edit any necessary information through a form that pops up.[URL]...
What I'd like to do, if possible, is add a button to the two right columns(I already put one in the Dock Out Time column) which will be invisible if the column is set or will set the current time to the column. Setting the time for those two columns is already handled through the update form, but my supervisor asked me to try and see if this was possible.
Those two Time columns are Templatefields(since I format the display time from what is actually in the DB) and I added an asp button in the ItemTemplate for that Set Button in the picture.Is this even possible to do and if so, how would I access this button in the code behind so I can add functionality(setting the time and hiding it if the column is not null)If it's not really possible to have two items like this in a templatefield I can just make 2 extra columns for these buttons but I think this would look much cleaner.

I am trying to export gridview (HTML Based) to a pdf in asp.net+vb.net (backend). When I click on the Export to PDF button the download window shows, but when you click on open Adobe reader will open but displays the message
" Adobe Reader Could not open 'test[1].pdf' because it is either not a supported file type or because the file has been damaged ( for example, it was sent as an email attachment and wasn't correctly decoded) ".
The coding for export to pdf is same for 5 different reports of which 4 are working fine, as well as export to Excel is also working fine for all 5 reports. Does it have any relation with the itextsharp dll version? (I am using itextsharp version 3.1.1.0)

I need to convert fdf files to pdf in asp.net using vb. I found some code that I'm trying to learn from. What I would like to do is upload the fdf file and then output a pdf to a directory and email it out. The fdf files are coming from a shared linux/php host (using the php fdf functions is all I can do here on this host) that are emailed to a central inbox. I'm going to pick up the files from the inbox and upload them to a win/asp.net box to convert to pdf.The code i found is below.
* Dim pdfFlat As New MemoryStream() * Dim pdfReader As New PdfReader(context.Request.MapPath(pdfFormFileName)) * Dim pdfStamper As New PdfStamper(pdfReader, pdfFlat) * ' bind fields from fdf... * Dim fdfReader As New FdfReader(context.Request.InputStream) * Dim pdfForm As AcroFields = pdfStamper.AcroFields *

I want to convert a string to a Gridview.
So I tried this[code]...
But the strGridView had a blue underline that says string cannot be converted to GridView so I tried this[code]...
But now it is giving the error gvwName cannot be converted to Integer.
Is it really being converted into an integer when I cast it like this?
How should I convert string into a gridview or another objects like checkbox?

I have a bunch of PDFs that I'm just trying to open, resize the page, and then save. I'm also hoping that the file sizes will shrink significantly doing so. I am using iTextSharp and the resizing works just fine, but the file size is nearly identical, ever so slightly larger in fact. Here's the function I have now:

I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?

I have an instance where I have a logo image as part of some artwork..If a user uploads a new logo I have a form field which is larger than the default logo.I then use that form field to position the new image.
The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo..
what I have done is:foreach (var imageField in imageReplacements)
{
fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null);
fields.RegenerateField(imageField.Key);
PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber);
float[] logoArea = fields.GetFieldPositions(imageField.Key);
[Code]...
The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.is there a way to set a stacking order on layers?

Dim datatable As PdfPTable = New PdfPTable(4)
Dim page As Rectangle = document.PageSize

even though im decrementing last_pos by the height of the previous table, they still lap over in a weird way like this:
