    <p>I have this code to return a list of fund sources for our organization.</p> <pre><code> Dim FundSourceList As New List(Of FundSource) Dim fs As New FundSource If results.Count &gt; 0 Then For Each result In results fs.FundID = result.Item("strFundID") fs.FundDescription = result.Item("txtFundIDDescr") fs.ShortFundDescription = result.Item("txtFundIDDescrShort") FundSourceList.Add(fs) Next End If Return FundSourceList </code></pre> <p>The problem is that when I loop through the resulting FundSourceList all it shows is the last value. For example, if I have three fund sources (state, federal, athletic), then when I use this code to loop through all I get listed is athletic, athletic, athletic.</p> <pre><code> For Each FundSource In FundSources Debug.Print(FundSource.FundDescription) Next </code></pre> <p>So I change the code to this. I moved the creation of the fs variable inside the loop.</p> <pre><code> Dim results = From result In dsResult.Tables(0) Select result Dim FundSourceList As New List(Of FundSource) If results.Count &gt; 0 Then For Each result In results Dim fs As New FundSource fs.FundID = result.Item("strFundID") fs.FundDescription = result.Item("txtFundIDDescr") fs.ShortFundDescription = result.Item("txtFundIDDescrShort") FundSourceList.Add(fs) Next End If Return FundSourceList </code></pre> <p>This works fine but now I'm creating a new class over and over again. It seems a little inefficient to me. Can I not create the class outside the loop and use it over and over again? Thanks.</p>

    1. CO+1 for the question because the Subject is informative, the tags look right, and everything is clear enough that a non-VB.NET user (that's me) gets the gist.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
