Mar 14, 20101. 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?

View 4 RepliesFirst Dataset - Dataadapter Namespace - How To Reference
Jun 25, 2010How 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.
