Better late than never? Some addition for Keith's suggestion which is basically the right one. Truth is, that you have to deal with sorting on gridView_Sorting event. There is no need to DataBind() the GridView earlier, for example in Page_Load event. There you should only call the GridView.Sort() method instead of .DataBind(). Here is how it goes: <pre><code>Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then Me.gridView.Sort(Request.QueryString("sortExpression"), Request.QueryString("sortDirection")) End If End Sub </code></pre> Next let's have a look on gridView_Sorting event. There you have to push the datasource to the right sorting. GridView itself does not handle that (in this case at least). <pre><code>Protected Sub gridView_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles gridView.Sorting If IsPostBack Then e.Cancel = True Dim sortDir As SortDirection = SortDirection.Ascending If e.SortExpression = Me.Q_SortExpression And Me.Q_SortDirection = SortDirection.Ascending Then sortDir = SortDirection.Descending End If RedirectMe(e.SortExpression, sortDir) Else Dim sortExpr As String = e.SortExpression + " " + IIf(e.SortDirection = SortDirection.Ascending, "ASC", "DESC") Dim dv As System.Data.DataView = Me.dsrcView.Select(New DataSourceSelectArguments(sortExpr)) Me.gridView.DataSource = dv Me.gridView.DataBind() End If End Sub </code></pre> No need to code any sorting functionality in data source like passing sort parameters to stored procedure. All sorting takes place in the above pieces of code. Moreover, it's good to have the gridView.EnableViewState switched to False which causes the page to be much lighter for the network traffic and for the browser as well. Can do that as the grid is entirely recreated whenever the page is post back. Have a nice day! Martin

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.
