RE: new menu control is very slow

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>

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!
