Dear all,

I have a master page with two menus. In fact, I want both menus to remain selected after I pick an item from the second menu.

When I click the first menu, the second menu populates from my web.sitemap but when I click the second menu, the pages "reloads" and looses the selections in both menus. If i click the first menu item again, then the page works as intended.

How can I programatically click the selected item from the top menu? Is that the right solution? I am planning to add some controls into the contentplaceholder dynamically driven from the second menu.

If you run my code, you will understand what I am talking about.

I posted all my code here

the relevant lines of code are here:

Did you manage to solve this one? If not, I have a potential solution for you. You could use a MultiView control to give the impression that separate sub-pages are being opened. Not ideal, I know, but at least it leaves the top level selection active.

No, I was not able to. I had to remove the databindings from the menus. Only the last menu item remains selected. I guess the solution is to add extra code to climb up the selected item all the way to the root and select it (apply the selected style)

Another approach is to do it via javascript but I will try the first aproach.

Hi,

You can try to use microsoft's CSS Menu Adapter of the ASP.NET 2.0 CSS Friendly Control Adapters collection, it is much more flexible then the Standar menu control.

Hope it helps.

I'm already using that, but thanks for the suggestion. I may have to abandon the Menu control and SiteMap. Instead, I think I may have to hard-wire my navigation buttons. Not as flexible, but OK if my site structure remains stable (which it will).

I don't know if you're still struggling with this, but I recently came across this post, which has solved the problem for me.

I figure out a simpler way!

The concept is as follows:

1. When the user clicks on the first menu, save the Menu1.SelectedItem reference into a session or something.
2. When the user clicks on the second menu, set the saved reference selected property to true

but for some reasons I was not able to save an object reference so I had to tweak the approach:

1. When the user clicks on the first menu, save the Menu1.SelectedItem.DataPath (or the index count of the selected item) into a session. or something such as lastTopMenuItemDataPath
2. When the user clicks on the second menu, select the menu item from the first menu that matches the first menu.

Having said the solution, here is the code:

For the master page:

<asp:Menu ID="Menu2" runat="server" DataSourceID="SiteMapDataSource2" MaximumDynamicDisplayLevels="0">
    <StaticMenuItemStyle CssClass="menuItem" />
    <StaticSelectedStyle CssClass="menuItemSelected" />
    <StaticHoverStyle CssClass="menuItemHover" />
</asp:Menu>
<asp:SiteMapDataSource ID="SiteMapDataSource2" runat="server" ShowStartingNode="false" StartingNodeOffset="1" />

<asp:Menu ID="Menu1" OnPreRender="setRef" runat="server" DataSourceID="SiteMapDataSource1" MaximumDynamicDisplayLevels="0" Orientation="Horizontal">
    <StaticMenuItemStyle CssClass="menuItem" />
    <StaticSelectedStyle CssClass="menuItemSelected" />
    <StaticHoverStyle CssClass="menuItemHover" />
</asp:Menu>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false"  />

<asp:ContentPlaceHolder OnPreRender="getRef" ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>

The master page code behind:

public partial class MasterPage : System.Web.UI.MasterPage {

    protected void setRef(object sender, EventArgs e) {
        if (Menu1.SelectedItem != null) Session["lastTopMenuItemDataPath"] = Menu1.SelectedItem.DataPath;
    }
    protected void getRef(object sender, EventArgs e) {
        string ldp = Session["lastTopMenuItemDataPath"].ToString();
        if(ldp !=null) foreach (MenuItem m in Menu1.Items) m.Selected = (m.DataPath == ldp);
    }
}

hey

I also have two menus, to datasources, 1 web.sitemap

and I tried your trick.it works

but I have some other problems with menu.

maybe you can give me some advice..

If I click on the first (horizontal menu) menu, than the menu on the left shows the sitemap nodes.

but the content page,does not update/shows the content of the page clicked in the first tab

also If I chose 1 page of the 2nd menu (left), the menu itself, does not longer display the subnote from the first menu

it displays the subnotes/menus which are set in datasource2 to starting node

( I programmatically change the startingnode of the second menu, like found in a post the forum

using cases in the master.cs )

may you have any idea how to keep the right subnotes/menus displayed?

greetings

solved my problem
