Access Request.QueryString in Master Page?

[james]

Hey Guys,

Do you have any idea how to acces Request.QueryString in a MasterPage?
I need to use it to modify my sitemap.

My code is:

public partial class MasterPage : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
SiteMap.SiteMapResolve += new
SiteMapResolveEventHandler(this.ResolveAdapter);
}

SiteMapNode ResolveAdapter(object sender, SiteMapResolveEventArgs
e)
{
SiteMapNode currentNode = SiteMap.CurrentNode.Clone(true);
string realm =
ContentPlaceHolder1.Page.Request.QueryString["realm"];
currentNode.Url += "?realm=" + realm;
return currentNode;
}

Nevermind. I used HttpContext.Current.Request.QueryString["realm"];

Don't forget to test to see if the Request.QueryString[] array item is not
null before you access it, otherwise you're going to end up with
nullreference errors when the querystring variable isn't present or
misspelled.

Hi,

Don't forget to test to see if the Request.QueryString[] array item is not
null before you access it, otherwise you're going to end up with
nullreference errors when the querystring variable isn't present or
misspelled.

Just to be nitpicking, the QueryString array won't be null if the
variable is mispelled, so you should also test if the variable itself is
not null:

if ( this.Request != null
&& this.Request.QueryString != null
&& this.Request.QueryString[ "realm" ] != null )
{
// Do some work
}

HTH,
