Asp.net - Refactoring: Gridview Export To CSV File

Sep 15, 2009

These routines (vb.net) allow you to dump a gridview to CSV, even if there are templated controls in the cells. It works, but I'm not thrilled with it.

What improvements should I make and why?

Private Shared Function CsvFormatted(ByVal t As String) As String
If t.Contains(",") Then
t = """" + t + """"

Export A GridView To Excel?

Mar 30, 2009

I would like to export a GridView to excel, which is easy enough. But above the grid, in Excel, I would like some other information for identification. Can I somehow export things other than gridviews while then putting in the gridview below?

Edit:For some reason when the GridView1 is visible and I try to export, the entire page exports and not just the gridview. Not sure why!

Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click

How To Export GridView To PDF Using ITextSharp

Nov 18, 2011

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)

How To Export Selected GridView Rows

Jan 11, 2011

I have a gridview which gets its input from a database with sql. There is a column with checkboxes in the gridview, so you can select which row you want to export. There is also a column that's called "Project Number". When you push the button "Export" the program should figure out which row is selected, get the project number from this row and connect to the database to get the data from the selected projectnumber. I already got the part where it gets the selected checkboxes. But I'm stuck at the part where it gets the projectnumber from the selected row. Must be something with Datakeys I think.

IDE :: Refactoring Does Not Work (enough) In VB

Sep 28, 2009

I use VS 2005 and VB.NET. I have a class A. This class A is an empty class(no functions, no members). I wrote the following code: Dim _a as new A(); Dim code as String = _a.GetCode() In the same situation, the C# refactoring tool in VS 2005 IDE propose me to create a method in the A class internal string GetCode(){ }

The VB.NET compiles does not propose anything. There is a way to implement the functions when I need it in code, or I need to planify all my methods before using the class?

.net - Refactoring A Field Into A Property?

Jun 7, 2012

I am currently learning vb.net for my new job and I have mixed feelings over public fields. I see many arguments about them hurting the encapsulation. In python, the common practice is to keep things simple and use fields when they are enough. If we want to add logic later, we just refactor them into a property without breaking anything for the client code.In the codebase I am working with I see huge classes containing dozen of properties like:

How To Approach Refactoring A Class

Jul 24, 2009

I recently started a project and needed to do some integration with LDAP via DirectoryServices. I've done this in other apps so I went into one of them to see how I did it -- why reinvent the wheel right? Well, while this wheel works, it was developed years ago and kinda smells (it's wooden, firmly attached to the previous vehicle, hard to repair and produces a potentially bumpy ride).So I thought to myself, this is the perfect time to refactor this puppy and make it more portable, reusable, reliable, easier to configure etc. Now that's fine and dandy, but then I started feeling a tad overwhelmed regarding to where to start. Should it be a separate library? How should it be configured? Should it use IoC? DI?

So my [admittedly subjective] question is this -- given a relatively small, but quite useful class like the one below, what is a good approach to refactoring it? What questions do you ask and how do you decide what to implement or not implement? Where do you draw the line regarding configuration flexibility? [Note: Please don't bash this code too much okay? It was written a long time ago and has functioned perfectly well baked into an in house application.]

Public Shared Function AuthenticateUser(ByVal id As String, ByVal password As String) As Boolean
Dim path As String = GetUserPath(id)

Asp.net - Export To Excel File As .zip To Reduce File Size - Compress Xmldata Before Sending It To The Client?

Jul 8, 2010

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.
