Please Help

 

I have a Datagrid like

 

<asp:DataGrid ID="dgCargo_Det" Runat="server" AutoGenerateColumns="False">

<Columns>

<asp:TemplateColumn HeaderText="No Of Pkgs">

<ItemTemplate>

<asp:TextBox id="TxtPkgs" runat="server"></asp:TextBox>

</ItemTemplate>

</asp:TemplateColumn>

 

<asp:TemplateColumn HeaderText="Pkg Type">

<ItemTemplate>

<asp:TextBox ID="TxtPkgType" Runat="server"></asp:TextBox>

</ItemTemplate>

</asp:TemplateColumn>

 

Page_Load

 

Dim DTCargoDet = New DataTable

If Session("DG_CargoDet") Is Nothing Then

DTCargoDet.Columns.Add(New DataColumn("NO_OF_PKG", GetType(String)))

DTCargoDet.Columns.Add(New DataColumn("CARGO_TYPE", GetType(String)))

Else

DTCargoDet = CType(Session("DG_CargoDet"), DataTable)

End If

Dim dr As DataRow = DTCargoDet.NewRow()

DTCargoDet.Rows.Add(dr)

Dim Dv = New DataView(DTCargoDet)

dgCargo_Det.DataSource = Dv

dgCargo_Det.DataBind()

 

If I click Button The Datagrid is dynamically generatings rows

but it is not showing the value of textbox.Got it.

It is showing empty textboxes.

 

Please help to retrieve the old value.
