Master Pages, Themes and Navigation Controls

Re: trouble linking A menu control using sitemap datasource to MultiView Control?

As an alternative, I am doing the following: You can add a Query string parameter to the target url, then assign the View index on form load. If your MenuControl is encapsulated in a usercontrol or on a Master page, this should give you the flexibility to move Multiview items to separate pages. In my case the page I am modifying has grown very large, and I want the ability to break it up.
Update: I am not currenlty using a sitemap, but a seperate XML file with a 'pagemode' attribute mapped to 'Value'. I image the 'pagemode' attribute could be added to the existing sitemap, however I am uncertain if it can be mapped. If not perhaps you can get the XmlElement in the code below.

    Public Property MenuPageMode() As String
        Get
            Return ViewState("MenuPageMode")
        End Get
        Set(ByVal value As String)
            ViewState("MenuPageMode") = value
        End Set End Property Private Sub mnuLeftNavigation_Load(ByVal sender As Object, ByVal e As System.EventArgs) _
            Handles mnuLeftNavigation.Load
        Dim reqPM As String = Request("pagemode")
        If Len(reqPM) > 0 Then MenuPageMode = reqPM Else
            MenuPageMode = 2
        End If
    End Sub

    Private Sub mnuLeftNavigation_MenuItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) _
            Handles mnuLeftNavigation.MenuItemDataBound
        'Dim xePage As XmlElement = CType(e.Item.DataItem, XmlElement) ' Use XmlElement if no Value
        e.Item.NavigateUrl = String.Format("{0}?pagemode={1}", e.Item.NavigateUrl, e.Item.Value) 
        If e.Item.Value = MenuPageMode Then e.Item.Selected = True
    End Sub

Hi,

Base on your description, you want to change the MultiView's ActiveViewIndex in the menuItem click event, but the menuItenm click event cannot be fired, right?

In fact, If the menuitem's navigateURL or URL is not null or empty, when you click on it , the page will be redirect to the new page directly without postback, so the menuitem event be fired.

So, you can try to do like this:

1. Add the menuitems in the aspx file not use the sitemap, because if the sitemapnode's url 's empty, the menuitem is unclickable.

<asp:Menu ID="Menu1" runat="server" OnMenuItemClick="Menu1_MenuItemClick">
                        <Items>
                            <asp:MenuItem  Text="Home"  Value="1">
                            </asp:MenuItem>
                            <asp:MenuItem  Text="About" Value="2">
                            </asp:MenuItem>
                        </Items>
                    </asp:Menu>

2. Redirect the new page in the codebehind:

 protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
    {
        if (e.Item.Text == "Home")
        {
            MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value);

            Response.Redirect("~/MenuEvent/CAse/Default.aspx");
        }
    }

Hope it helps.

trouble linking A menu control using sitemap datasource to MultiView Control?

Having trouble linking A menu control using sitemap datasource
to MultiView and View Web Server Controls

I need CustMultview( the multiview control) to use method SetActiveView
to get ViewID called from Menucontrol using selected menuitem Title or NavigateUrl

I know I need to add
// if (!IsPostBack)
// {

I want (e.Item.text) to equal View view

so I can utilize

// CustMultview.SetActiveView(view)

// to set the View ID

or should I use
// protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
// {
// MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value);
