edit not working when using masterpage

[dirkjan75]

So, two pages: first one is a simple datasource & gridview with edit button, is working. Second is the same code but then in a contentplaceholder page, linked to a masterpage. Now the code is not working, when editing, it returns empty fields in steds of edited fields.

<%@ Page Title="" Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="AllCP.aspx.vb" Inherits="Pages_AllCP" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlace" Runat="Server">
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataKeyNames="cp_id" DataSourceID="ObjectDataSource1">
            <Columns>
                <asp:CommandField ShowEditButton="True" />
                <asp:BoundField DataField="cp_id" HeaderText="cp_id" InsertVisible="False"

                <asp:BoundField DataField="tussenvoegsel" HeaderText="tussenvoegsel"

                <asp:BoundField DataField="datum_invoer" HeaderText="datum_invoer"

            </UpdateParameters>
        </asp:ObjectDataSource>
</asp:Content>

The masterpage looks like this:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Page.IsPostBack Then
            gridview1.databind()
        End If

    End Sub

try this. I was having issues with my masterpage the other day because of not rebinding the control. Let me know how that works for you.

The problem was that in the masterpage I had a second <form> tag, (used some CSS style that was in HTML). After deleting this form tag, the editing worked fine.
