why the following code bombs with a NullReference exception.

I just want to output the html for the menu control to a string, if I remove the line that adds the new menu item or I change the control to a calander control instead of a menu control the it works fine.
I am testing my website in numerous browers and have discovered (amazingly) that the asp:menu
control does not render properly in both the above browsers! Given that these browsers must account for
a large part of internet traffic it is curious that microsoft have not fixed this. I have looked at CSS Friendly but
if looks like a lot of work and change for my websites just for the one control that does not work.
I am having a problem with rendering a menu control inside a server control. I am getting an error in the RenderContents override method when I try to render the Menu Control. The error I am getting is an Object Reference error. The code is below...
[Code]....
I've encountered was appears to be a strange bug with the menu control, and alas, I am unable to find much useful information on it (which leads me to believe I have something installed or confingured incorrectly). Here the problem:
When declaring a menu control with a staticHoverStyle, for example:
<asp:Menu
ID="navMenu"
DataSourceID="srcSiteMap" [code]....
Has no effect on the behavior of the control once it's rendered, neither in Firefox nor IE.In fact, using the source code at
http://msdn.microsoft.com/en-us/library/ms366731.aspx with no modifications also results in the hoverstyle not working.
This problem seems to be "fixed" if you specify the css attribute declaratively, for example, StaticMenuItemStyle-BackColor="Yellow".
Alternatively, if you specify RenderingMode="table" then the hoverstyle seems to work. It's only when you're using a cssclass with a list that things seem to mess up.
Finally, I notice that in the rendered html, the control embeds some styles between /* <![CDATA[ */ and /* ]]> */ comments that affects the final appearance of the menu control, sometimes overwriting a cssclass you specified (ex: the margin for dynamic menus can only be controlled with the HorizontalOffset property, and not by css). This is undesirable, but I don't see anything that seems to overwrite the behavior of hover elements. Actually, the .hoveritem class doesn't appear anywhere in the markup at all, but when you specify the StaticMenuItemStyle-BackColor property, then the value is rendered correctly in this block of styles.
I hate tables - don't want to use tables, unless I have tabular data to display. A menu is not tabular data (as far as I am concerned.) I was elated to see that in asp.net 4 - the menu control renders as a <ul> <li>, instead of as a table. However - try as I might, I can not get a horizontally orientated Menu to split into even columns, and text align center. FYI - I don't use fixed width - so I can't just set a width to 1000 - and separate it into even columns. Besides that, I want it to change width dynamically, based on the number of "columns (menuItems)" there are. Is it possible to spread out the <li> menu items evenly across the space I provide for them in their containing div or will I have to quite using menu controls, and start using JQuery Menu's?
View 2 RepliesI've migrated a test site to asp.net 4.0 to take advantage of the list renderingmode for a menu. Having the UL and LI should be easier than the table rendering.I'm making progress, (still have work to do, just ignore the odd border) however one issue continues to plague the testing. IN IE 6,7,8, as the page is rendering, it appears the menu is flickering and trying to render as a vertical menu instead of the correct
orientation which is horizontal. In Moz, Chrome, Sarafi, Opera, I don't get this behavior.
The menu is styled with CSS however I'm not opposed to adding some corrective code directly to the masterpage that holds the menu. I'd apprecate a suggestion as to how to solve this because as it is, it is not usable.Here is the link to the test site.

Im trying to render a gridview control to a string as part of a confirmation email to be sent to a customer. When I try to render it, I get an exception.
ex = {"Control 'OrderLineItems1_gridOrder' of type 'GridView' must be placed inside a form tag with runat=server."}
The code which is attempting to render the control is

The RenderControl() raises the aforementioned exception. Has anyone succeeded in doing something similar.
Is there a way to add/delete/update the default classes (for instance AspNet-Menu-WithChildren,AspNet-Menu-NonLink ) of the html generated by the asp.net menu or treeview control? I am using CSSAdapters so the menu control renders in a list format instead of table format.
View 1 RepliesCurrently I have a menu control on my webform in ASP.Net 4.0 :
<div class="PNMenu">
<asp:SiteMapDataSource ID="PNSiteMap" runat="server" ShowStartingNode="false" />
<asp:Menu ID="PNMainMenu" runat="server" DataSourceID="PNSiteMap" RenderingMode="List" Orientation="Horizontal" CssClass="PN-PrimaryNavMenu" >
</asp:Menu>
</div>
I am trying to style the menu control to allow the menu items to float to the right of the container, however I am unable to do so as whenever I am styling the a, ul or li it keeps getting overidded by asp.net and floats everything left.

View 1 RepliesWe have to develop an application which has a Vertical left pane menu control which displays all the web pages (A,B,C say). Now if user is in page A and filled some data and clicks on menu control to go to page B, all the data in page A needs to be saved. Also if all the required field in page A are not filled and user navigated to page B, there will be one ! sign after the menu so that user can understand that there some some more fields need to be filled up.
We are planning to place the menu control in the Mater page. Please give me some direction to do this. My question is:
1. If user change menu (In Master Page), how should we save data?
2. How should we display the ! in the menu control?
I am doing a rework on one of my sites and I am attempting to use the asp:menu control.
I am using images in the static and dynamic menus. Hard coded at this point.
On my local machine it works fine but when I upload to the server, the image on the dynamci menus do not appear.
Instead I just get white space where the images should be.
Here is the code:

I know that the code depicted below will not work but I am including it to convey the idea of what I wish to accomplish. I want to use a different SiteMap to construct the menu on the displayed page for each of three different classes of service (COS).
I set a session variable named "COS" at the login and want to test its value prior to rendering each page. I want to display a menu based upon the appropriate COS. Here is my first stab at it but I know that I cannot include <asp:...> controls within the "case" statements. Can anyone suggest methods of doing this? I know C# and can use that but I do not know how to select the proper sitemap within the <menu> control. I am also using a CSS in my production version.

<asp:SiteMapDataSource ID="Menu" runat="server" ShowStartingNode="false" />
<asp:Menu ID="Menu1" runat="server" Orientation="Horizontal" OnMenuItemDataBound="OnMenuItemDataBound" DataSourceID="Menu" >
<LevelMenuItemStyles>
<asp:MenuItemStyle CssClass="Menu" />
<asp:MenuItemStyle CssClass="Level" />
</LevelMenuItemStyles>
</asp:Menu>
<siteMapNode url="javascript:Logout" title="Logout" description="Logout" roles="*">

I am building a command line application and I need to transform data within my application's classes to text.
It would make my life easy if I could use ASPX files to render my data into the target text format.
To achieve that, I need to be able to render an aspx file outside IIS. The following article explains how:

The article is developed in 2003.
Is there any better way to so achieve similar result in .NET 4.0? Does MVC make this easier? Is this very memory/performance intensive? I have to create a new ApplicationHost anytime my command line application is executed. Is this approach reliable enough to be used in an environment with high throughput?
