Web Forms :: Extracting GridView To PDF File?

I referenced this page, how to extract data from a gridview on a webpage. [URL] ....
I can extract to a Word, Excel and CSV but I can't to a pdf file. I get the following error:

Im writing a bit of code that will extract the contents of a gridview to excel. I have all the parts working except for one. In my page_load i fetch the data from the database and then have the user select some options which filters the data and then the gridview gets populated. The problem im having is that the Response call doesnt seem to get the data from the gridview if i enclose the database fetch command within if not page.ispostback in the page_load
I have some test pages where i just fetched the data from the database bound it in a gridview in the Page_load. then on a button click export the data in the gridview to excel. Works fine if i DONT enclose the fetch command within not page.ispostback but outputs an empty excel file if i do.
Now i have to use not page.ispostback in the actual webpages because the users have to make selections which will filter the original dataset. How do i get this to work?
The page is also implementing AJAX if that helps. Here's an example of what i have:

I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).

i'm currently doing a shopping website. The customer will have to selected the item they want to buy and it will appear in the detail view when they click add in the grid view. I need the info inside the detail view to be insert into a database call Orderlist.
i've try using INSERT INTO OrderList (ProductName, Price,) VALUES (@ProductName, @Price) but it don't seems to work.
Was it because i can't insert it like this as it is detailview? This method can work if is Textbox instead of detailview.

This may be something simple, but I am completely new to ASP.NET. I have been reading some tutorials based on W3Schools, and I have copied one of the files and tried to play with it by changing an element with a value to storing that same value in the attribute. Here is the edited XML (my.xml):
<?xml version="1.0" encoding="ISO-8859-1"?>
<countries>
<country>
<text value="N">Norway</text>
</country>
<country>
<text value="S">Sweden</text>
</country>
</countries>
I want to extract the N and S and use them as tooltips. Here is my aspx file:
<%@ Import Namespace="System.Data" %>
<script runat="server">
sub Page_Load
if Not Page.IsPostBack then
dim mycdcatalog=New DataSet
my.ReadXml(MapPath("my.xml"))
my.DataSource=my
my.DataBind()
end if
end sub
</script>
<html>
<body>
form runat="server">
<asp:Repeater id="my" runat="server">
HeaderTemplate>
table border="1" width="100%">
<tr>
<th>Name</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td title="<%#Container.DataItem.("text").Attributes["value"]%><%#Container.DataItem("text")%> </td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
</form>
</body>
</html>
What have I missed here?

Every morning we get a few hundred emails from our various customers servers that tell us how their backup went that previous night. Somebody has to go through these and fill out an excel spread sheet. I would like to automate this, we have our own server running a .NET application so i can schedule something every morning.
There are two main parts. The first is i want to know how to create a table that has customers down the left and dates accross the right, they are called pivot tables in access but not sure how to recreate them in MSSQL and to do it on the fly as i dont want to have to sit there entering 100's of days at a time.
The second is that differnt customers use differnt backup solutions, so i want to write some code that scans a particular mailbox in exchange, looks for emails that have come in in the past 12 hours, look at the from email address and match that to one in the database, then according to the subject line it will be able to identify what type of backup solution it is, e.g. if it says "Backup Exec Job completd Sucessfully" it knows its backup exec and will look for a particular text (completed successfully, completed with exceptions, no media etc) and can insert that, or if its a differnet backup solution then go and look at a specific place in that email for it.

I have a dataGrid with ButtonColumns in my asp page and I would like to do the following to:
When a row is clicked, I want to be able to:
1 - Hide all rows and display only the clicked row dynamically/on the fly.
trying to loop thru the datagrid and display only the Row index passed by the OnITemComman - but unsure of how to do it.
2 - Extract the row values (all cells in the row) to use as parameters in a query.
Used many ways of many examples but i always get a blank value. Managed to get the button text in the class but i need the full row values not just the cell clicked.

Is there a reliable way to extract text from PDF? The first thought that comes to mind is that PDF may have multiple columns and the extraction mechanism needs to know the logical structure somehow. I understand that some PDF docs are "tagged" but I'd need to support pretty much any PDF document.
Any third party components to the rescue here?

I found an application that interacts with one of googles APIs that sends requests to the API and returns results to the web page. The owner of this app has made it publicly available and even though it is hosted on his server, it acts directly with the api from anyones browser. The source code in page source is available but since I dont know javascript, it is meaningless to me.
I would like to create an app that calls this web app and have it send requests to the API, and have the results parsed to a database. Would this be possible?
I have very little ASP experience and since trying to work through accessing the API itself is complicated since it involves using oAuth protocol and I am having a hard time with this with not much sample code available.
If this is possible, how can I get access to the results from this web app?

I have an HTML string like
<A HREF="/files/1234/mybook.b1">mybook.b1</A><br>11/24/2010 1:02 AM 991
I want to fetch only the date element from this string. i.e 11/24/2010 1:02 AM
I know i can do that using the substring method of string class but i need to implement a standard solution for this problem. i.e. fetch date from any html content if it contains a date element.

I have a Portable Bridge Notation formatted-file that I have to work with. I have already a few simple examples working by using indexing and substrings extracting what I need and I suppose for this PBN business it would suite me well since it isn't run too often. If I one the other hand would run that code like all the time (thinking of working with vCards) then I am worried about memory usage under high workload because of the high amout of temporary string variables created from all substrings and splits.
There are two other options available that I know of. Regex and StringReader / TextReader and I wanted some general opinion on what to use.
Intended usage is to extract to objects and serialize to json so that I can more easily work with or persist this information. Hell if it's fast enough I might even do it on the fly.

The task is: given a web application that returns a table with pagination, do a software that "reads and parses it" since there is nothing like a webservice that provides the raw data. It's like a "spider" or a "crawler" application to steal data that is not meant to be accessed programmatically.
Now the thing: the application is made with standart aspx webform engine, so nothing like standard URLs or posts, but the dreadful postback engine crowded with javascript and non accessible html. The pagination links call the infamous javascript:__doPostBack(param, param) so I think it wouldn't even work if I try even to simulate clicks on those links.
There are also inputs to filter the results and they are also part of the postback mechanism, so I can't simulate a regular post to get the results.
I was forced to do something like this in the past, but it was on a standard-like website with parameters in the querystring like pagesize and pagenumber so I was able to sort it out.
Anyone has a vague idea if this is doable, or if I should tell to my boss to quit asking me to do this retarded stuff?
EDIT: maybe I was a bit unclear about what I have to achieve. I have to parse, extract and convert that data in another format - let's say excel - and not just read it. And this stuff must be automated without user input. I don't think Selenium would cut it.
EDIT: I just blogged about this situation. If anyone is interested can check my post at [URL] and comment about that.
