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
View 1 RepliesI 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.
View 1 RepliesI 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 downloaded iTextSharp because it seems to be the most popular free one. But aftersearching the internet I am not really finding the information I need to get me started. The few tutorials I've found so far are too confusing. I know there's a book out there but I'm a student and don't want to spend the money. I just need really basic step-by-stepinformation, preferably with code in VB. The most basic tutorial I've found so far isTextSharp, but it's not working for me. I tried to follow it and came up with this code:
using System;
using System.Collections.Generic;
using System.Linq;

I'm wondering how can I put a header into my PDF file, cause I've tried the tutorials from here:And it has not worked.I've done this:

document.Header = head

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.

EDIT: forgot to mention, so better state this before anything else... I'm running VS 2005 with Framework 2.0.I have a GridView (gdvN) with 7 columns (N1, N2, N3, N4, Edit command e um Delete command). In the same aspx, 4 textbox (that would be a new line with new N1, N2, N3 and N4 values.).
After filling the textboxes and pressing a button, it was supposed to insert a Row in the gdvN.
[Code]...
Unfortunately that didn't solved, as it edits an existing row instead of adding one. As I can see, that may be two paths for this to be solved:Is there a way to make _newitem be created with the same structure as the gdvN rows. I didn't found how.Or there's another logic (or a mistake in the coding) I'm not looking?

how can i get the dataset from a gridview i have populated?
i tried this:
Dim importedDS As DataSet = gwResults.DataSource
but it's coming out blank all the time. is there another way?
I have a gridview in which I have set datasource as a datatable. Whatever update I make to the gridview, it should reflect only in the datatable and not to the database. When I click update, I have to get the row number of a particular row which I want to update. How can I get the row number in rowupdating event of gridview in order to update the datatable? Suppose I have a datakey and if I get that unique id, how can I update the datatable which is the datasource?
