Hello All,

I'm getting this error on a ASP .NET apps:

Index 2 is not non-negative and below total rows count.

Line 443:
Line 444: Dim ParentTableView As New
DataView(DsSellers1.Tables("SELLERS"))
Line 445: Dim CurrentRowView As DataRowView =
ParentTableView(Me.cboSellers.SelectedValue)
Line 446:
Line 447: grdSellers.DataSource =
CurrentRowView.CreateChildView("SellersRelation")

Stop at Line 445. Here is my source code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Try
If Not Page.IsPostBack Then
'Fill all DataAdapters into DsSellers dataset.
Me.daSellers.Fill(Me.DsSellers1)
Me.daDoc_Type.Fill(Me.DsSellers1)
Me.daOccupancy.Fill(Me.DsSellers1)
Me.daProduct_Code.Fill(Me.DsSellers1)
Me.daProperty_Type.Fill(Me.DsSellers1)
Me.daPurpose.Fill(Me.DsSellers1)

'Data bind all data to their controls.
Me.cboSellers.DataBind()
End If

Catch ex As Exception
Response.Write(ex.Message)
Finally
Me.ConnWBOC5177.Close()
Me.ConnWBOC5177.Dispose()
End Try

End Sub

Private Sub cboSellers_SelectedIndexChanged(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
cboSellers.SelectedIndexChanged
Dim ParentColumn As DataColumn
Dim ChildColumn As DataColumn

ParentColumn = DsSellers1.Tables("SELLERS").Columns("SELLER_ID")
ChildColumn =
DsSellers1.Tables("DOC_TYPE_LISTING").Columns("SELLER_ID")

Dim drSellers As New DataRelation("SellersRelation", ParentColumn,
ChildColumn)
DsSellers1.Relations.Add(drSellers)

Dim ParentTableView As New DataView(DsSellers1.Tables("SELLERS"))
Dim CurrentRowView As DataRowView =
ParentTableView(Me.cboSellers.SelectedValue)

grdSellers.DataSource =
CurrentRowView.CreateChildView("SellersRelation")
grdSellers.DataBind()
End Sub

Can someone help me? I just want to able find related data from the
DropDownList control to the Datagrid use DataRelation object. The Datagrid
will be using it's own queries for Select, Insert, Delete, Update.
