C# - Extracting String Data - From The Right-hand Side?

Jan 8, 2010

In my code I will be presented with url strings to pages... All I want to do is to extract the page name, nothing else... (Example)

string page1 = "./default.aspx";
string page2 = "./subfolder/gallery.aspx";
string page3 = "./subfolder/anotherSubfolder/demo.aspx";

I've used the substring feature before, but I am struggling with this one since I only want the page names which are on the right hand side, I basically want to chop of everything else (folder paths).. all I want to end up with is default.aspx, gallery.aspx and demo.aspx

C# - Best Option For Extracting String Data?

Mar 6, 2010

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.

Extracting Data From Dynamic Array In C#?

Nov 18, 2009

I am having a little difficulty taking the values from a dynamic array into fixed variables. What I am doing is this:

text is pasted into a textbox on a web form, we don't know how many lines this text will consist of so a dynamic array is used to collect the data. I would like to take the array data and set them to fixed variables within the script but i would like the array loop to create the variables dependant on how many lines the textbox conatins. eg text1, text2, text3 and so on. Is there a way to create a loop that will create unique variables and set them to the position value of the array until it reaches the end of the array collection for use further on in the script?

C# - Extracting Data From An ASPX Page?

Sep 14, 2010

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.

Forms Data Controls :: Extracting Gridview To Excel Using Response Class?

Mar 31, 2011

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:

Forms Data Controls :: Extracting Edited Values From GridView, To Update/insert To Database?

Jul 28, 2010

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).

Forms Data Controls :: Display Divs Side By Side In A ListView?

Jan 23, 2010

I'm trying to customize a ListView control to display like a GridView so that I can enable users to see and update multiple database records at a time.

In the ItemTemplate I've encased all the fields in divs with a style class that would give each div a set-width and left & right borders so that all fields would lineup like a column, however the divs display underneath each other rather than side by side. I tried nesting all the "field divs" in a <p></p> but this doesn't work.

I've spent much time Googling my question and haven't been able to find a clear answer. I'm teaching myself ASP.Net on my own with books and online tutorials and these materials have not shed much light on this particular issue either as of yet.

Mvc2 Data Annotations Validation (Client Side Works, Server Side Doesnt?

Aug 12, 2010

I'm using an entity model with metadata annotations. My controller method looks like this...

if (!ModelState.IsValid)
return View(model);
return RedirectToAction("Index");

If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.

This is the top portion of my view....

<% using (Html.BeginForm())
<%: Html.ValidationSummary(true) %>

I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?

Forms Data Controls :: Client Side Code To Pass Values To Server Side Variable?

Mar 13, 2008

I have ListBox_SelectedTextChanged() method that creates another list box in the runtime as follows:

// Get Action Level List
lbxActionLevel = new
ListBox();lbxActionLevel.ID =
"ddlA" + i.ToString();
lbxActionLevel.Width = 100;
lbxActionLevel.Rows = 2;
SqlDataReader dr =

while (dr.Read())
ListItem lAction =
new ListItem();
lAction.Text = dr.GetString(1).Trim();
lAction.Value = Convert.ToString(dr.GetInt32(0));
lbxActionLevel.SelectedIndex = 0;

I guess because this lbxActionLevel object is generated on the fly, I can't get the selection values once I click the "Done" button. I don't want the lbxActionLevel to do autopostback bacause for some reason most of the user input gets wiped out. Is there a way to get the user selection collected on the client side (javascript) and pass it to the C# code?

Good Way To Split Data Into Two Side-by-side HTML Tables?

Jul 28, 2010

Basically, given data like this:

Col 1 | Col 2
1 7
2 8
3 9
4 10
5 11
6 12

I want to have the page display something like this:

Col 1 | Col 2 Col 1 | Col 2
1 7 4 10
2 8 5 11
3 9 6 12

The purpose of course is that I have extra horizontal space with less vertical space. Obviously it doesn't take a rocket scientist to pull this off, but I feel like I might be missing a cleaner/easier solution than my own, perhaps using CSS or clever use of an existing ASP.NET control. It seems like a common enough requirement, but I can't quite get the search terms right to find what I'm looking for.
