Hi all

I have following code to display data in DetailsView, but now for editing the dataset from DetailsView I need to read data fromt eh textbox of DetailsView, how can i do that??

<asp:templatefield headertext="Module Weight" >
<itemtemplate>
<asp:label id="FirstNameLabel"
Text= '<%# Eval("au_fname") %>'
runat="server"/>
</itemtemplate>
<Edititemtemplate>
<asp:TextBox id="LastNameLabel"
Text= '<%# DataBinder.Eval(Container.DataItem,"Model_Wt_kg") %>'
runat="server"/>
</Edititemtemplate>
</asp:templatefield>

In C# code behind to display data in these fields the code which is working fine:
dbcon.Open();
adp = new OleDbDataAdapter(sqlStmt,dbcon);
adp.Fill(ds, "Product");
closeConnection();
table1 = ds.Tables["Product"];
