The image will be the link.

If you are trying to place a hyperlink over top an image? If so then you need to use CSS to position the elements.

A picture may be worth a thousand words but being able to clearly define your problem and expected result is worth more here.

ASP.NET GridView already has Pager functionality. http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.allowpaging.aspx[^]

If this doesn't fit your needs then try this. http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.pagertemplate.aspx[^]

wouldn't it be nice if MSDN pages, like the ones you linked to, would show us some pictures so we can see what we could get from those classes, methods, and properties? I never understood why they are so reluctant to use some more graphics and images...

How can I access a method on a child page from its master page ?

How can I access a method on a child page from its master page ?

I have a Datagrid on my masterpage. Is acts as filter for the content and it´s pages below.
As I have the Selection Event after the PageLoad Event (Master and Child), I wana call the Content Page Comand directly from the masterpage event.

Thanks.

You can't really call a content page from the master page. The master page doesn't know what page is using it, that's the point. You can, however, create an event on the master page and have a content page subscribe to it.

The Page property gives access to the content page.

True enough but the page object would need to be cast to an object that had the method needed, either as a concrete class or interface. The master page would need to know too much in my view.
It would also limit the ability to change the master page if required. I like the flexibility of subscribing to an event.

Not if you put one method per interface.

So adding more and more interfaces and implementations when more functionality is needed? Rube Goldberg would be proud.

Events do have at least one distinct advantage. They are a public part of the class, which makes it more obvious that the functionality is available.

I will assume you are using C#. Use this.Page.

First, you will create an interface that defines the methods you want to call (I put this code in INamedObject.cs):

namespace WebApplication70
{
    public interface INamedObject
    {
        string GetName();
    }
}

Then, your Primary.Master will access this.Page and cast it as an INamedObject to call GetName():

ASP.NET

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Primary.master.cs" Inherits="WebApplication70.Primary" %>
<%@ Import Namespace="WebApplication70" %>

<html>
<head runat="server">
    <title>Master/Page Example</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <h1><asp:Label runat="server" ID="lblPageName" /></h1>
        <asp:ContentPlaceHolder ID="body" runat="server" />
    </div>
    </form>
</body>
</html>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
        {
            string pageName;
            if (this.Page is INamedObject)
            {
                pageName = (this.Page as INamedObject).GetName();
            }
            else
            {
                pageName = "Unknown Page";
            }
            lblPageName.Text = pageName;
        }
</script>

Create a page, Default.aspx, that makes use of the masterpage:

ASP.NET

<%@ Page Language="C#" MasterPageFile="~/Primary.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication70.Default" %>

<asp:Content ContentPlaceHolderID="body" runat="server">
    <p>This is the default page.</p>
</asp:Content>

In the code behind (Default.aspx.cs), you will implement the interface:

namespace WebApplication70
{
    public partial class Default : System.Web.UI.Page, INamedObject
    {
        public string GetName()
        {
            return "Default.aspx";
        }
    }
}

I'd avoid doing this though, as far as possible. By implementing in this way you increase the coupling between the master page and this particular page. If this pattern were to be repeated it would result in a maintenance nightmare.
Depending on the reason the OP wants to pass information up to the MasterPage, there are normally other mechanisms.

Often times, the purpose of the masterpage is to reuse content, and coupling isn't a factor. Besides, my example isn't tightly coupled... it makes use of an interface, which allows any page to implement the desired behavior (or not).

Still, an event driven technique (observer pattern) may be cleaner, though I'm not sure because I can't tell exactly what the OP wants to do.

Oh I know what a MasterPage is for, and what you suggest breaks the intended pattern which spells trouble. You class mightn't be tightlight coupled, but it is more tightly coupled and this is a factor in maintainability. The eventing mechanism is just plain cleaner.

Maybe, depending on the OP's needs. Could you give a clear code example of what you are envisioning?
