[Code]....
Well the trouble is. when i fill my dataset it gets the first line in my excel sheet and put it like a colum title and make it an invalid line that i can't use any more.
1. As per my knowledge we use dataadapters/dataset when we want to deal with the huge amount of column/data. Is there anyway that if I want to update one or two columns in a table without using dataadapter/dataset?
2. There is a way that without clicking a button we can get the data using objectdatasource, I mean to say that there is no vb.net data in the code behind then how to debug if there is not data in vb.net in code behind.
How do I reference my data adapter? I've been running through some tutorials (worx Professional ASP.Net 4 in c#) but have become stuck after creating my data adapter and trying to reference it. Steps I have taken to get this far: Added an 'App_Code' folder to project and added a dataset in it. I dropped a data adapter onto the visual dataset designer screen and followed the prompts for select statement etc. I tested the query and it worked. So under the App_Code folder I have a 'Product.xsd' file, which has 3 files under it (Product cs,xsc and xss files.) Created a new object 'Web-> Webform'. I dropped a gridview onto the form and a couple of textboxes and a button for filtering (my select is narrowed down by a date range).Tried to put code into c# section to fill dataset on page load but ran into problems. Code attached below.

I have a DataSet containing a small two-by-two table. When I call the da.Update(DataTable) method, I get the infamous DBConcurrencyException. However, the change does get updated in the actual database. What's up with that? I checked the RowState for both rows and one is Modified while the other is Unchanged. I would very much like to get rid of that exception!

I have almost got this all working but one thing. What i am doing is SELECTING a number of details from a table which is for job vacancies. I am then displaying the job_name, a short description about the job and finally the location's the job is available in..If you look on this page:http://kidsunlimited.co.uk/vacancies_test.aspx
You will see a list of Vacancies shown BY job name. The problem occurs when the job is available in more than once location. Take a look at the Cook vacancy. It should be reading as Cook, then the description and then location which in this case there are 2.But instead it mixes them up and displays one location before the description and one after..This is the code i have :
