new menu control is very slow

I was wondering if anyone else found that the new ASP.NET Menu control had
very slow responsivenes on complex pages.

So I inserted this control in a WebControl, bound it to a siteMapDataSource,
and applied a little logic (for roles...but of course we have in-house
security, so I can't use RoleProvider...but that's another question for
later!), and finally apply a few styles with css. Then, just plopped the
..ascx in the Master page.

I don't notice any performance woes when the page is simple, such as a
couple controls and some content. However, some of the reports we generate
are fairly large and we use GridViews to display them. This is when the menu
REALLY slows down. Hovering on a menu item for up to 10 seconds before the
dynamic menus drop down is common.

I've turned of ViewSate, aborted using logic in the code-behind for 'roles',
and even tried removing the styles. Even implementing paging for the
GridViews so they aren't so large! Nothing seems to work.

Can anyone help!?

Thanks!

Hi Lucas,

Welcome to ASPNET newsgroup.
Regarding on the Menu control displaying slow problem, I'm think whether
this is a clientside specific issue since the dynamic menu popup using the
standard output client scripts. So would you also tried testing the problem
page on from some other clients to see whether all of them suffer this
problem? If the problem occurs on all the client, I think you can try
create a reproduce page which contains only the necessary items so that we
can perform some tests on local side...

Thanks,

Steven Cheng

I have deployed the project we are working on to a server for our testers and
they have found the same problem. Other developers on the team are not
excempt from this, either.

I can give you some coded stuff, if that's what you are looking for, that
closely emulates the troubles:     (sorry if this gets too long!)
--------------------
Default.aspx:

<form id="form1" runat="server">
    <div>
    <asp:Menu ID="siteMenu" runat="server" CssClass="MS"
DataSourceID="SiteMapDataSource1"
        DisappearAfter="300" Orientation="Horizontal">
        <StaticHoverStyle BackColor="#66957A"/>
        <StaticMenuItemStyle BackColor="#4c83b2"/>
        <DynamicHoverStyle BackColor="#66957A"/>
        <DynamicMenuItemStyle BackColor="#4c83b2"/>
        <DynamicMenuStyle BackColor="#4c83b2"/>
    </asp:Menu>
    <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server"
ShowStartingNode="false" />
    </div>
    <br />
    <div>
    <asp:GridView ID="GridView1" runat="server" EnableViewState="False">
        <HeaderStyle BackColor="Gray" ForeColor="White" />
    </asp:GridView>
    </div>
</form>

--------------------
Default.aspx.cs:

    protected void Page_Load(object sender, EventArgs e)
    {
    //Some string of names.
    string[] Names = ("Bob the Builder,Suzy Snoozy,Frank the Tank,Wendy just
Wendy,Steve Stevenson").Split(',');

    //A new dataset with columns.
    DataSet newDataSet = new DataSet();
    newDataSet.Tables.Add();
    foreach (string name in Names)
        newDataSet.Tables[0].Columns.Add(name);

    //Build a DataSet for the GridView.
    //Add more rows by changing i's capacity (ie, 100, 1000, 10000) to see
incremental effects.
    for (int i = 0; i < 10; i++)
    {
        DataRow newRow = newDataSet.Tables[0].NewRow();
        foreach (string name in Names)
        newRow[name] = name;
        newDataSet.Tables[0].Rows.InsertAt(newRow, i);
    }

    //Bind it.
    GridView1.DataSource = newDataSet.Tables[0].DefaultView;
    GridView1.DataBind();
    }

        <siteMapNode title="record4" url="Pages/Record4.aspx"/>
    </siteMapNode>
    </siteMapNode>
    <siteMapNode title="review">
    <siteMapNode title="pending">
        <siteMapNode title="review1" url="Pages/Review1.aspx"/>
        <siteMapNode title="review2" url="Pages/Review2.aspx"/>

    <siteMapNode title="pending" url="Pages/Audit1.aspx"/>
    <siteMapNode title="completed" url="Pages/Audit2.aspx"/>
    </siteMapNode>
</siteMapNode>

So I just created a new website and used the default page/sitemap, etc.,
added links in the siteMap, and added some names to the GridView. Obviously
controls on the real page will be much more complex, but even on this page
you can see the delay by changing the number of records in the GridView in
the code-behind (changing i's capacity). Let me know if this works for you.

Thanks for the welcome, Steven, and thanks for your help!

Hi Lucas,

Thanks for your response.
I've just have a test on the page you provided, seems the menu's dynamic
sub items are poped out quickly, so I'm still thinking this could be a
clientside related issue. Can you find any other boxes that dosn't suffer
the problem with the same page?

Yes, I have noticed some other controls acting very slow, now that you
mention it. So I added a bunch more, and expanded the menu to test. The
outcome was horrendous!

What are we doing wrong on the client side?! We aren't modifing/adding to
the WebResource.axd file. I guess I always assumed it was the menu after
looking at the source from the page and seeing the bloated table renderings
for the menu.

Thanks again for your help, Steven!

Could it be the client box lack of some certain resources, is the client
machine powerful or are their many programs running on it? Also, you can
try saving the ASP.NET page's output as a static html file and then open it
in clientside's IE browser to see whether it still works slow...

Thanks,

Hi Steven and Lucas,
I've got same problem of Lucas, and the code he posted here looks very
similar to the one we are using. The asp:menu (.Net 2.0) control worked
fine on IE as long as the items were far less than 100, then its
performances became increasingly bad, while in Firefox everything looks
fine. Now we have something less than 1000 items on the menu (which is
not quite complicated, we use 2 menu controls in each page, first has 4
main items, second 5, then most of the items are in the first two main
items of the first menu, but things are not too deep, just two levels),
and on IE it is completely unusable, while on Firefox works quite good.
The only think I could think about is that our pages are labelled as
XHTML but it is not yet validating (just a few errors, anyway), and
maybe Firefox is managing that better than IE.
Any idea or suggestion?

To elaborate a bit, here is how a single menu item look like in the HTML
source code:

***** start *****
<tr>
            <td><img src="Images/SeperatorVertical.jpg" alt="" /></td>
        </tr><tr onmouseover="Menu_HoverDynamic(this)"
onmouseout="Menu_Unhover(this)" onkeyup="Menu_Key(this)"
id="ctl00_Header1_Menu1n364">
            <td><table class="MenuFontLevel2 ctl00_Header1_Menu1_4"
cellpadding="0" cellspacing="0" border="0" width="100%">
                <tr>
                    <td style="white-space:nowrap;width:100%;"><a
class="ctl00_Header1_Menu1_1 MenuFontLevel2 ctl00_Header1_Menu1_3"
href="http://localhost/Development/Applications/Company.Web.Application.Website/Common/Page.aspx?PageID=446"
style="border-style:none;font-size:1em;">PAGE</a></td>
                </tr>
            </table></td>
        </tr>
***** end *****

Cleaning it a bit, here is what we have at element level:
<tr><td><img/></td></tr>
<tr><td><table><tr><td><a>PAGE</a></td></tr></table></td></tr>

So for each menu item, we get 2 tr, the first one with just a td with an
img inside, the second with a table, but again made up from only one td
and tr, which are there to support one link.

We will rename things to make the code less heavy to download, and I
guess we will head in that direction (i.e. turning Header 1 to Hd, or
Menu1 to Mn, and so on), but I don't believe that will help too much on
the slowness of the menu control side.

Now I sorted that out, I got a "This Page Is Valid XHTML 1.0
Transitional!" from the w3c validator, but the menu control is still not
usable (5 sec is an optimistic guess of the latency).

Hi everyone.

I can report the same issues here. It is definitely a "client side
problem". That is - it's a product of the size of the menu, the power
of your computer and the quality of the implementation of the
Javascript parser on the browser you use.

Like Alessandro Riolo, I can report that the Menu performance is far
superior in Firefox. The project I'm working on now contains about 400
menu elements, and this renders smoothly on Firefox (<200 ms response),
but uses 3-5 seconds for each expanding/collapsing in IE.

Since both the Menu class and IE is a product from Microsoft, I'd
suggest they look into improving the implementation in either of these.
Until then, I'll see if I can find a third-party implementation of a
similar Menu control that works better.

Glad to see I'm not going bonkers!

In previous projects, I've used the skmMenu, but noticed that they haven't
implemented anything new lately. Maybe I'll toy with that a little... If you
find a suitable replacement to this menu, I would be interested in checking
it out.

Thanks everyone.

I am having the same problem. Any solutions for this? Datasource is 64K XML
file. Menu is useless in IE, Very fast in Firefox. Noone in the company uses
firefox - I need to get this working.
