                    lnkSubmit.CommandArgument = (e.Row.RowIndex + 1).ToString()
                    AddHandler lnkSubmit.Click, AddressOf OnSubmit
                    e.Row.Cells(9).Controls.Add(New Label() With {.Text = " "})

    I think you can put the linkbutton on the front.The LinkButton Click event will be implemented using the RowCommand

    event, so when the LinkButton is clicked, the RowCommand event will fire to get the cell value of the ASP.Net GridView.


     <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCommand="GridView1_RowCommand">
            <asp:TemplateField HeaderText="Name" ItemStyle-Width="150">
                    <asp:TextBox ID="txtName" runat="server" Text='<%# Eval("Name") %>' />
            <asp:BoundField DataField="Country" HeaderText="Country" ItemStyle-Width="150px" />
                    <asp:LinkButton Text="Select" runat="server" CommandName="Select" CommandArgument="<%# Container.DataItemIndex %>" />
    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
            If Not Me.IsPostBack Then
                Dim dt As New DataTable()
                dt.Columns.AddRange(New DataColumn(2) {New DataColumn("Id"), New DataColumn("Name"), New DataColumn("Country")})
                dt.Rows.Add(1, "John Hammond", "United States")
                dt.Rows.Add(2, "Mudassar Khan", "India")
                dt.Rows.Add(3, "Suzanne Mathews", "France")
                dt.Rows.Add(4, "Robert Schidner", "Russia")
                GridView1.DataSource = dt
            End If
        End Sub
        Protected Sub GridView1_RowCommand(sender As Object, e As GridViewCommandEventArgs)
            If e.CommandName = "Select" Then
                Dim rowIndex As Integer = Convert.ToInt32(e.CommandArgument)
                Dim row As GridViewRow = GridView1.Rows(rowIndex)
                Dim name As String = TryCast(row.FindControl("txtName"), TextBox).Text
                Dim country As String = row.Cells(1).Text
                ClientScript.RegisterStartupScript(Me.GetType(), "alert", "alert('Name: " & name & "\nCountry: " & country + "');", True)
            End If
        End Sub

    Use Gridview.SelectedIndexChanged event

    <asp:GridView ID="GridView1" runat="server" DataSourceID="MyData">
        <asp:CommandField ShowSelectButton="True" />
        <asp:BoundField DataField="CustomerId" HeaderText="CustomerId" SortExpression="CustomerId" />
        <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
        <asp:BoundField DataField="Value" HeaderText="Value" SortExpression="Value" />
    Protected Sub GridView1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridView1.SelectedIndexChanged
    Dim row As GridViewRow = GridView1.SelectedRow
    Dim message As String = "CustomerId: " & row.Cells(1).Text & "\n Name: " & row.Cells(2).Text & "\n Value: " & row.Cells(3).Text
    ClientScript.RegisterStartupScript(Me.GetType(), "alert", "alert('" & message & "');", True)
      End Sub
