Hi Guys: Along these lines:When I use a DataTable, DataSet, I get Rows on any select. I can limit the data returned to a couple of columns but it seems I have to provide values for an entire row or the values are messed up during an update. I don't think I can just set and update a couple of columns using the DataSet Update function. Is this the case with Linq? Can you just Select a couple of columns, set them and then apply an update for them or will that tip other columns in the original row? I hope I explained this well enough to understand and my understanding is correct. I had problems like this some time ago so always just read entire rows, update whatever columns I want then ReWrite the entire row. This is, of course, pretty inefficient and I even had to write a TableAdapter extension to avoid Optimistic Concurrency for a particular update since it was so blasted slow and unnessisary for the particular update. Anyway, while on the Linq topic I thought I would ask in case someone has had experience with this situation.

By the way, I've found an alternative for this. Locate the table in the designer window, press shortcut key, open add sub-menu, click property - it will take you to the list of the columns for that table focussing an edit box forcing you to specify a name for the new property. Pressing the shift+tab creates a new property with the default name property1, since it's not required one can delete it by selecting it in the listbox and pressing the dell key. I know that this is not the right way to go about it, but this is the only way I'm able to know to go about it.

It has new feature called LINQ(Language-Integrated Query) designed to further increased the speed/objectorientation of working with database. It has added an O/R designer for thispurpose. User can drag-drop tables from server explorer to the designer to create a data context which is the focle point of LINQ. Dragging/dropping part is okay because Jaws has a shortcut key for this purpose. The problem I'm facing is how to access properties of the table object (don't confuse properties here with the general properties of any components such as Name which can be accessed via f4 in O/R as well, but with the properties hereI mean by columns of a table) so that I can delete specific columns that Idon't require (only from the table class of O/R designer and not from thedatabase). Has anybody gotten an idea as to how it can be done?P.S. I've not been able to find a shortcut key for this anywhere on thenet. P.P.S. Sighted folks can access it with the mouse, but there's no text written at that point to make jaws cursor do the job.
