Question

Access forms to vb.net

Asked by: TikkTakk-Aicon

I´m working on a project where a customer wants to move an Access forms system to the web.  There is an SQL database behind this all.  I have started this projcet in vb.net and am reading all kinds of data into formviews and datagrids.  Now I have to start working on the editing and inserting part, what is the best way to do this (using formview, detailsview, datagrid etc.).  For example, when a new surveilance is registered you have to choose items from dropdownlists (from other tables in the database) and then insert it all into a table (that has foreign key references to other tables of course).
I´m kind of new to vb.net and don´t know the best (and shortest) way to do this.

The "best way" for me is not necessarily the best way for you.  The answer depends on your requirements.  If you want the web pages to act like Access, then you would probably need to work some magic.  If you just want regular web pages that are similar, but optimized for ASP.NET, then you could do that pretty easily with either a FormView or DetailsView.  For data-binding requirements, you have plenty of options, but the ASP.NET way is to use an ObjectDataSource, SqlDataSource, LinqDataSource (depending on version), etc.  If you need to edit data, then you would define edit templates, and switch the control to edit mode.  The specifics depend on which direction you would like to take.

Sorry for the late reply.

I have the first page which lists up data from the SQL database and then I can navigate to the next page to view details.  On that page I would like to edit and insert new surveilance into the database.  I have a listview on that page, is it possible to make that insert- and editable or do you recommend using formview ?

 

by: TheLearnedOnePosted on 2009-10-28 at 08:45:15ID: 25684541

You can continue to use the ListView, if you want to edit data.

Here is a reference article:

Using ASP.NET 3.5's ListView and DataPager Controls: Editing Data
http://www.4guysfromrolla.com/articles/061009-1.aspx

"Whenever one of the Edit buttons is clicked a postback ensues and the ListView begins its editing workflow. (In the screen shot above the "Edit button" is the pencil icon and is implemented as an ImageButton.) This workflow proceeds as follows:

The ListView raises its ItemEditing event.
The ListView sets its EditIndex property to the index of the row whose Edit button was clicked.
The ListView rebinds to its data source.
The row whose index corresponds to the EditIndex value has its EditItemTemplate rendered (instead of its ItemTemplate)"

Ok, thanks for this.  The data in the listview is taken from two tables, using a stored proc is probably the best way to update the data in these two tables right ?

 

by: TheLearnedOnePosted on 2009-10-28 at 10:25:51ID: 25685848

Refer to my first comment--"best" for me is not "best" for you.  A stored procedure, with parameters for each table, sounds like a good way to go in this case.

For me, I don't use stored procedures, since any database changes are out of my control (DBAs handle data changes), but code changes are in my control.
