Question

On an ASP.NET page, I have a SqlDataSource configured with the following SELECT command:

SELECT AVG(Rating) FROM [Ratings] WHERE ([AlbumID] = @AlbumID)

How would I place that average value into a label?

Answer 1

You need to use FormView control to put the Label in.

Something like this:

<asp:formview id="formview1" runat="server" datasourceid="your-datasource-id">
    <itemtemplate>
        <asp:label id="label1" runat="server" text='<%# Eval("column-name") %>' />
    </itemtemplate>
</asp:formview>

Replace your-datasource-id and column-name in the above code.

PS: you might need to alter the query to have a column-name for that one value:

SELECT AVG(Rating) AS "average" FROM [Ratings] WHERE ([AlbumID] = @AlbumID)
