Web Forms :: 3.5 - Test If System.Web.Routing.dll Exists

Jan 7, 2010

I've sucefully runned it in my local server (Windows Server 2003 Standart) but after tried several times upload it to my hosting, it never works. The web hosting company told first that they didn't had System.Web.Routing.dll installed (but they said that they've .NET 3.5 installed..), then i've copied the dll to Bin folder and again with no sucess. Can someone give me a very basic example of and website using System.Web.Routing.dll so i can do the "final" test on webhost before i go to the company because they say that they have 3.5 installed but i'm starting to see that they didn't have? If possible, is there another way to test if this dll is installed in web hosting? (test all .dll running for example)

Forms Data Controls :: Export Edited DetailsView Information To Csv File?

Feb 10, 2010

I have a DetailsView on my page that will be populated with a users information once they navigate to it. If they need to edit anything in it, they will click the "Edit" link, make their changes and click the "Update" link. Upon update, I want to export/append their information to a csv so we can bulk update a master db.

I already have it populating and I have the function: "SqlDataSource1_Updated" - but don't know how to get their information into a csv file in code behind.

Forms Data Controls :: Gridview And Detailsview - To Click Two Times On The Select Button To View The Detailsview?

Nov 17, 2010

I“m trying to link the gridview to detailsview and I used this page as my inspiration:

http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx

But I“m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.

Web Forms :: FTP Download - How To Check File Exists

Dec 7, 2010

What is the way to :

1) Check if a file exists on an FTP site.

2) Sample the size of that ftp file (3) times to ensure the file is ready for downloading.

We have some classes doing this already but they are using WebRequestMethods.Ftp.ListDirectoryDetails and then searching there in if file exists. I am hoping there are some clean ways to do this.

Forms Data Controls :: Check If A GridView Exists?

Dec 9, 2010

I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.

GridView1 has data about the order, like status, payment details.

GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities

GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block

if GridView3 isnot nothing then

'getting some data from the cells in GridView3
endif

but the code still executes.
