Okay, been using the webGrid control since 2006.  My first foray into use a hierarchical table.  Looking at that sample code for this example:  http://samples.infragistics.com/2009.2/WebFeatureBrowser/Default.aspx, I've got pretty much the same thing set up in my sample page. 

One question is why is there no register tag in the sample.  In my page I just have my normal WebGrid regiter tag:  <%@ Register TagPrefix="igtbl" Namespace="Infragistics.WebUI.UltraWebGrid" Assembly="Infragistics2.WebUI.UltraWebGrid.v9.1, Version=9.1.20091.1015, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" %>

 Is this correct?

I can't find anything in the sample that I am not doing in my page.  My page loads, but the grid is not hierarchical,  It just looks like a normal web grid.  I am however inside a master page, don't know it that is a problem

 In my code behind I have this:

    Protected Sub UG1_DataBinding(ByVal sender As Object, ByVal e As System.EventArgs) Handles UG1.dataBinding

        Dim ConnStr As String = HWCSoft.CostAcctDataAccess.CostAcctDAL.cConnStr

        Dim SqlStr As String = ""

        Dim dataSource As String = Request.QueryString("DataSource").ToString.Trim

        Dim camKey As String = Request.QueryString("CamKey").ToString.Trim

        Dim dbId As String = HWCSoft.CostAcctDataAccess.CostAcctDAL.sqlGetDBID(dataSource)

        SqlStr = String.Format("Exec GetPhaseIISummary {0}, {1}", dbId, camKey)

        SqlHelper.FillDataset(ConnStr, CommandType.Text, SqlStr, ds, New String() {"dsGroup"})

        SqlStr = String.Format("Exec GetPhaseIIDetails {0}, {1}", dbId, camKey)

        SqlHelper.FillDataset(ConnStr, CommandType.Text, SqlStr, ds, New String() {"dsCdm"})

        Try

            'Dim dRelGrp As New DataRelation("GroupIds", ds.Tables("dsGroup").Columns("GroupId"), ds.Tables("dsCdm").Columns("GroupId"), False)

            'ds.Relations.Add(dRelGrp)

            ds.Relations.Add("GroupIds", ds.Tables("dsGroup").Columns("GroupId"), ds.Tables("dsCdm").Columns("GroupId"))

            Me.UG1.DataSource = ds.Tables("dsGroup").DefaultView

        Catch x As System.Exception

            Dim s As String = x.Message

            Dim m As String = s

        End Try

    End Sub
