Representing columns data in Visual Basic .Net from a SQL database

Hello,

I am writing a simple app in Visual Basic 2008 that will pull some data from a SQL database using a rather complex query and represent it in a form. Once this data is retrieved, a complex set of operations are carried out and displayed on another form in a similar tabular format

What is the best element to use to display this data (table, grid, etc). I know I can use datagridview, but i dont need the connection to be "live" - just extraction. Nothing needs to be written back to the database either. I imagine a listbox would work, but I would prefer that the end user have a simplistic excel-like interface.

Any example declarations would be greatly appreciated.

Thanks in advance.

But the DataGridView don't need to save the change back to the database. In fact you have to write some code in order to do that.

As said by JPaulino, datagridview does not write back to the database automatically if you do not configure it to do so. So you can retrieve the data from the db into a datatable. Use that datatable as the datasource of the grid and any changes made would remain in the datatable.

Here is an example of how to load and display using datatable


dim dTable as new datatable
dim dbadp as new sqldataadapter("select * from tablename", connectionstring)
dbadp.fill(dTable)
dbadp.dispose
datagridview1.DataSource = dTable

Open in new window
