    copied!<p>I am trying to pull the contents of an AS/400 file back to a data-bound .NET WinForms DataGridView (VS 2010). The query itself is no problem, and I am able to bind everything using the DataSource property of the grid. Data comes back with no issues.</p> <p>The problem I <strong>am</strong> having is that all date/time fields come back as string literals, making it impossible to sort. Moreover, it comes back using our default AS/400 formats (yyyy-dd-mm and hh.mm.ss). I would like them to come back as actual Date/Time fields so that they can be sorted and I can control the output format (I would prefer MM/dd/yyyy and hh:mm:ss AMPM). I tried combining the two fields into one using the TIMESTAMP format, but that just gave me a combined string. </p> <p>I would like to avoid doing any field massaging if at all possible, and I would like to keep the table data-bound for ease of coding, although if I have to turn off column auto-generation I will do so. I would also like to avoid doing any intermediary LINQ queries, as I lose the ability to sort by columns out of the box (and the examples I have seen online for adding this back in are all long and painful).</p> <p>Can anybody suggest anything? Thanks!</p> <p>EDIT: Code example. SQL to query the values (with names changed to protect the innocent) is:</p> <pre><code>SELECT MYDATE, MYTIME, TIMESTAMP(MYDATE, MYTIME) FROM LIBNAME.FILENAME WHERE &lt;blah blah blah&gt; </code></pre> <p>SQL query gets written to a DataTable via an OleDbDataAdapter.Fill command.</p> <pre><code>Dim myTable as New DataTable Using adapter As New OleDbDataAdapter adapter.SelectCommand = New OleDbCommand(&lt;sql statement&gt;, &lt;AS/400 Connection&gt;) adapter.Fill(myTable) Return myTable End Using </code></pre> <p>DataTable gets stuffed into a DataGridView:</p> <pre><code>grid.DataSource = FunctionCallToGrabTheDataAbove </code></pre> <p>Pretty straightforward (and trying to keep it that way if possible)</p>
 

Querying!
