chkBox datagrid question

[Guest]

Hello all,

I have a datagrid with a checkbox as a template. I connected my two
chekboxes in the template to my my datasource in the propeties menu. But I
get this error flagged at line 33.
"Index 0 is not non-negative and below total rows count. "
<asp:TemplateColumn HeaderText="Sold">
Line 32: <ItemTemplate>
<<<Line 33: <asp:CheckBox id=chkITsold runat="server"
AutoPostBack="True" Checked='<%# DataBinder.Eval(DsUinv1,
"Tables[IMSProducts].DefaultView.>>>[0].Sold") %>'>
Line 34: </asp:CheckBox>
Line 35: </ItemTemplate>
When I disconnect the checkboxes from the db, it' fine.
I also ahave a quick question on my code for the checkboxe in my item
command. Having problems with a "Object not refrenced error" on my chkbox
line. Not sure if this has something to do with not being connected to the
database, or I coded the line wrong.
Private Sub grdUinv_ItemCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs) Handles
grdUinv.ItemCommand

If e.Item.ItemType = ListItemType.Pager Or _
e.Item.ItemType = ListItemType.Header Then Exit Sub
''' grdUinv.EditItemIndex = -1


Dim btn As Button = CType(e.CommandSource, Button)
If btn.Text = "Edit" Then
txbProductID.Text = e.Item.Cells(0).Text
txtProdName.Text = e.Item.Cells(1).Text
txtModNum.Text = e.Item.Cells(2).Text
txtSrp.Text = Microsoft.VisualBasic.Right(e.Item.Cells(3).Text, _
Len(e.Item.Cells(4).Text) - 1)
txtCost.Text = Microsoft.VisualBasic.Right(e.Item.Cells(4).Text, _
Len(e.Item.Cells(5).Text) - 1)
txtQty.Text = e.Item.Cells(5).Text
' chkEbay.Checked =
CType(e.Item.Cells(6).FindControl("chkEbay"), _
' CheckBox).Checked
chkSold.Checked =
CType(e.Item.Cells(6).FindControl("chkITSold"), CheckBox).Checked
pnlAdd.Visible = True
Else
' DeleteItem(grdUinv.DataKeys(e.Item.ItemIndex).ToString)

End If
btnSave.CommandArgument = ""
End Sub

I do have a panel below that I can ADD items to the database, including the
checkbox, that works just fine. My other columns work fine too, just the
chkbox on the datagrid is giving me flak!

TIA!!!!
