Change asp:menuitem properties from other programs

Question

Good afternoon.

I am using MS Visual Web Developer 2010 Express with VB.Net.

I have 3 web pages - Site.Master with Site.Master.vb, Login.aspx with Login.aspx.vb, CreateAccount.aspx with CreateAccount.aspx.vb

If I put the following statement in the Site.Master.vb Page_Load: NavigationMenu.Items.Item(2).Selectable = False it works fine. It makes the menu item unselectable. However, this is not where I want to do this.

I want to be able to make the menu items selectable/unselectable programatically thru other programs such as Login.aspx.vb and CreateAccount.aspx.vb. I realize that NavigationMenu is declared in Site.Master and not declared in Login.aspx.vb or CreateAccount.aspx.vb

How can I get this to work in Login.aspx.vb and CreateAccount.aspx.vb?

I tried to include sample code but I got: The code snippet in your post is formatted incorrectly. Please use the Code button in the editor toolbar when posting whitespace-sensitive text or curly braces

Thank you for your time.

Even if the control is on the master page, you can access it via pages that reference the master page.

See this MSDN article: http://msdn.microsoft.com/en-us/library/xxwa0ff0.aspx

You can also expose controls by creating public properties as described in this other asp.net article:

Thank you JorgeM. But, I don't get it. I read the articles and tried various things but I'm no closer than I was.

I'm including the code that I couldn't get to post the first time. All I want to do is access the NavigationMenu items and change their property values.

Thanks again.

Remove the code from your master page's code behind.

On the code behind for your login.aspx page, use the following:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim navMenu As Menu
        navMenu = CType(Master.FindControl("NavigationMenu"), Menu)
        navMenu.Items.Item(2).Selectable = False

    End Sub
