Troubles with focus() HELP

Hello Experts:

I've been getting help with setting focus on a textbox inside my editable datagrid.  Here is the paq'd question where I was helped:
Focus help
https://www.experts-exchange.com/questions/20816773/ASP-Net-Editable-datagrid-the-focus-command-HELP.html

It was working fine when we finished up this question.  I then got help on keeping the scrollback position on the datagrid here:

Anchor help
https://www.experts-exchange.com/questions/20823426/Retaining-scroll-position-on-asp-net-datagrid.html

This worked fine as it kept its scroll position after postback.

Then I realized that with both codes in the focus stopped working.  I hadn't changed the code at all for focus().  I need help getting this to work again.  If I remove the scrollback code the focus works again fine.
I've now even changed my datagrid from a boundcolumn for the focus to a template column like most of the examples suggest.

Currently my code for focus looks like this:
Sub DataGrid_Edit(Sender As Object, E As DataGridCommandEventArgs)
   
                        ' turn on editing for the selected row
   
                                                        
                              'Dim scriptJs As String
                              Dim commentBox As Textbox
                                            
         DataGrid1.EditItemIndex = e.Item.ItemIndex
         BindGrid()
             
         'CommentBox = DataGrid1.Items(e.Item.ItemIndex).Cells(6).FindControl("CommentBox")
         'scriptJs = "<script language=javascript>" & vbCrLf
         'scriptJs &= "document.getElementById('" & CommentBox.UniqueID & "').focus();" & vbCrLf
         'scriptJs &= "document.getElementById('" & CommentBox.UniqueID & "').select();" & vbCrLf
         'scriptJs &= "alert('Textbox focus')" & vbCrLf
         'scriptJs &= "<" & "/script>"
         'If (Not Me.IsStartupScriptRegistered("Startup")) Then
      '      Me.RegisterStartupScript("Startup", scriptJs)
        ' End If
       CommentBox = DataGrid1.Items(e.Item.ItemIndex).Cells(0).FindControl("CommentBox")
       RegisterStartupScript("focus", "<Script language=""JavaScript"">" & vbCrLf & _
       vbTab & "Form1." & CommentBox.ClientID & ".focus();" & _
       vbCrLf & vbTab & "Form1." & CommentBox.ClientID & ".select();"& _
       vbCrLf & "<" & "/script>")
               End Sub

You can still see the old code I was using from the help I was getting in the link above.  The new code functions the same as the old does.  Using UniqueID the select() is working but the focus() is not.  Using ClientID neither work.

The code I use for scrollback is here:

Sub DataGrid_ItemCommand(ByVal Source As Object, ByVal E As DataGridCommandEventArgs)
   
                        ' this event fires prior to all of the other commands
                        ' use it to provide a more graceful transition out of edit mode
   
                        'CheckIsEditing(e.CommandName)
      If(bookMark) Then
      bookmarkIndex = e.Item.ItemIndex
      Me.InsertScriptBlock(e.Item.UniqueID)
      End If
                                    
               End Sub

Sub DataGrid_ItemDataBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs)
            If(bookMark) Then
                  Dim anchor As New LiteralControl
                  
                  anchor.Text = "<a name=""#" + e.Item.UniqueID + """>"
                  e.Item.Cells(7).Controls.Add(anchor)
            End If
      End Sub
      
      Sub InsertScriptBlock(ByVal strItem As String)
            Dim jScript As New System.Text.StringBuilder
            jScript.Append("<script language=""JavaScript"">")
            jScript.Append("location.href=""#")
            jScript.Append(strItem)
            jScript.Append(""";")
            jScript.Append("<" & "/script>")
            
            Me.RegisterClientScriptBlock("Bookmark", jScript.ToString())
      End Sub

This is how my datagrid looks now:
<form runat="server" id="Form1">
          <asp:datagrid id="DataGrid1" runat="server"  Font-Size="10pt" ShowFooter="True" AutoGenerateColumns="False" width="90%" CellSpacing="2" GridLines="None" HorizontalAlign="Center" CellPadding="3" BackColor="White" ForeColor="Black" OnPageIndexChanged="DataGrid_Page" PageSize="25" AllowPaging="true" OnCancelCommand="DataGrid_Cancel" OnUpdateCommand="DataGrid_Update" OnEditCommand="DataGrid_Edit" OnItemCommand="DataGrid_ItemCommand" OnItemDataBound="DataGrid_ItemDataBound" DataKeyField="Control#">
            <HeaderStyle font-bold="True" forecolor="white" backcolor="#4A3C8C"></HeaderStyle>
            <PagerStyle horizontalalign="Right" backcolor="#C6C3C6" mode="NumericPages" font-size="smaller"></PagerStyle>
            <ItemStyle backcolor="#DEDFDE"></ItemStyle>
            <FooterStyle backcolor="#C6C3C6"></FooterStyle>
            <EditItemStyle Width="100%" BackColor="Cyan"></EditItemStyle>
            <Columns>
                <asp:BoundColumn DataField="Control#" ReadOnly="False" HeaderText="Cust. Number" />
                <asp:BoundColumn DataField="Customer Last Name" ReadOnly="True" HeaderText="Name" />
                <asp:HyperLinkColumn DataTextField="Reference#" HeaderText="Deal #" datanavigateurlfield="Reference#" datanavigateurlformatstring="dealno.aspx?Reference={0}" navigateurl="dealno.aspx" target="_blank" />
                <asp:BoundColumn DataField="Bank Name" ReadOnly="True" HeaderText="Bank Name" />
                <asp:BoundColumn DataField="SumAmt" DataFormatString="{0:c}" ReadOnly="True" HeaderText="Amount" />
                <asp:BoundColumn DataField="daysold" ReadOnly="True" HeaderText="Days Old" />
                <asp:TemplateColumn HeaderText="Comments">
                <ItemTemplate>
                <%# DataBinder.Eval(Container.DataItem, "CommentBox") %>
                </ItemTemplate>
                <EditItemTemplate>
                        <asp:TextBox id="CommentBox" runat="server" width="95%" Text='<%# DataBinder.Eval(Container.DataItem, "CommentBox") %>' />
                        </EditItemTemplate>
                        </asp:TemplateColumn>
                        <asp:EditCommandColumn ButtonType="LinkButton" UpdateText="Update" CancelText="Cancel" EditText="Edit" ItemStyle-Font-Size="smaller" ItemStyle-Width="7%"></asp:EditCommandColumn>
                        
            </Columns>
        </asp:datagrid>
        <br />
        <br />
        <asp:Label id="Message" runat="server" width="80%" forecolor="red" enableviewstate="false"></asp:Label>
    </form>

So the scrollback code works fine like it is here.  Doesn't matter if I use ClientID or UniqueID in this case.  There is one line that I changed from the help I was given here.  This: e.Item.Cells(7).Controls.Add(anchor) used to be this: e.Item.Cells(0).Controls.Add(anchor).  
I changed it because if I leave it at 0 it cuts out the first column in my datagrid.  I'm assuming it should point to the editcolumn?  My editcolumn is on the right side of the grid instead of the traditional left.  So its cell would be 7.

At this point I've given up.  I've worked through almost all online examples and still get the same results each time.  Is it impossible to mix the two here?  I need to be done with this so I can move on to some other changes so any help is appreciated!
