Enabling securityTrimming with Windows authentification

Patrick Olurotimi Ige — Fri, 11 Jan 2008 06:31:37 GMT

With the new Navigation controls in ASP.NET 2.0 you can easily setup security trimming with any provider you choose to use and a web.sitemap file or any other datasource you posses that can give you a menu structure.

I would provide a link to a sample on the net by Scott Gu the ASP.NET guru.
The samples include using both sql server and Windows Authentication

But when setting up this nice and easy handy stuff there are some issues :

1)You will not see your menu listed (nothing will appear)when your root Url is empty like below
<siteMapNode title="Home">
You will need to have a url node like so :
<siteMapNode url="default.aspx" title="Home">

<system.web>authorization>

<system.web>

</location>

This is what the provider will use to determine the authorization of each folders or files listed in your project
The above means only the roles IT and Managers would have access to the Admin folders you can also have a page set in there.

Although if you have the roles set below for the somepage.aspx like below

<siteMapNode url="somepage.aspx" title="Employee" roles="IT,Managers,Support />

If someone in a Support role logs in he would be able to see the somepage.aspx but when he/she clicks on it and try to login he would be denied access based on the authorization tag you declared above.

So you will notice that the security trimming is definitely done on the sitemapNode and the Url and if a user doesn't belong to a specific role not specified you won't see the link.

Hope this helps and happy coding

Error Control 'ctl00_ContentPlaceHolder1_gdViewExport' of type 'GridView' must be placed inside a form tag with runat=server

Patrick Olurotimi Ige — Fri, 02 Nov 2007 06:56:19 GMT

In the days of asp.net 1.1 when using DataGrid and exporting to Excel i never came across this error since there was no master pages etc..
But at the same time having master pages makes life easier and at the same time some troubles.
One of them is when using Ajax with GridView with a functionality to export to Excel.
The error you get is "Control 'ctl00_ContentPlaceHolder1_gdViewExport' of type 'GridView' must be placed inside a form tag with runat=server" when clicking on your export button.

After nearly pulling my head off i came across some sort of hint that when you have your

GridViewToExport.RenderControl (HtmlTextWriter) in your code

the page won't know what to do unless you call this method VerifyRenderingInServerForm method click on the link to
read more . It simply overrides the Render method to ensure that this control is nested in an HtmlForm server control .Anyway after wrapping the method as suggested it worked all well.

But now here comes another trouble when using UpdatePanel in you Gridview and cilck your export button you get error :

inside UpdatePanel control, it gives this error:
Sys.WebForms.PageRequestManagerParserErrorException: The message received from teh server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '<div> <table cells'.

And i'm sure you'd say argggg!

But doing EnableEventValidation="false" could solve your problem but in my case i need to use validation on my page.
But i knew some AsyncPostBackTrigger and PostBackTrigger exists after the Triggers even in the UpdatePanel So what i did was do :

<asp:PostBackTrigger ControlID="imgexcel" />

setting the ControlID to the control ID of my asp:imagebutton control

And bingo that did the trick

Error the Web server does not appear to have the FrontPage server extensions installed- Vista

Patrick Olurotimi Ige — Thu, 18 Oct 2007 08:21:13 GMT

I have a development laptop and i have vista ultimate installed. So i decided to put all my neccesary day to day development tools like vs.net 2005, sql server etc..
But i get error message :- Unable to open the Web 'http://localhost/project name'. The Web server does not appear to have the FrontPage server extensions installed.
when trying to create a new website project and i said to myself another microsft OS "VISTA".

So next thing to do looked for a solution and i found :this . After i started reading it i remembered i had the same issue when configuring Reporting Services 2005 on my vista machine nothing won't work and users had to be a member of admin..
So i closed the VS.NET 2005 IDE and now right clicked on the VS.NET link and "run as Administrator".
And now i could create a site using http:// without that ugly error bingo

This could save some other developers precious time.
