I m using multiple sitemaps in my website. The providers are defined in web.config file as:
[Code]....
[Code]....
Now I m trying to modify one of my xml file in memory to dynamically populate querystring but when I use
Dim currentNode
As
SiteMapNode =
SiteMap.CurrentNode.Clone(True)
I get Null in my currentNode and I cant point to the node.
There is an ashx file containing "ProcessRequest(HttpContext context)" method which gets triggered automatically. When and how does it get fired?Another question, How can I get the current QueryString when I am inside this file? When I type "context.Request.QueryString" it says it's null or empty although the address have arguments.
View 1 RepliesThe following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
I'm intermittently seeing this exception being thrown:
A potentially dangerous Request.QueryString value detected
However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.
How could this be? Are "dangerous" query strings being stripped from the log or something?
Encrypt request.querystring and Descrpt request.querystring

I need to rewrite the links of a breadcrumb menu because the pages in my website are hierarchical and the content is dependent of a querystring (i.e. Shop >> Category >> Item).I found in ASP Quickstart tutorials how to do this (http://quickstarts.asp.net/QuickStartv20/aspnet/doc/navigation/sitenavapi.aspx#resolve).

I am currently attempting to set a default value on an INSERT of a ListBox to a QueryString value. I am able to do this successfully in a DetailsView, however, it doesn't seem to work for a ListBox. Here is my code:
<InsertItemTemplate>
<asp:TextBox
ID="TextBox1"
runat="server"
value='<%# Request.QueryString["Item_ID"] %>'
Text='<%# Bind("Item_ID") %>'></asp:TextBox>
The syntax is accepted, however, when in insert mode, the value is not populated.

This works great in every browser, except IE. In Firefox and Safari it works as expected: it appended the following QueryString: "?campus=SELECTION". In IE, it doesn't do this at all. In fact, no QueryString is present in the URL.I have no idea what would be wrong. If you want to see the page in action: [URL]

I have been using a querystring to carry over the value of a DDL to the next page. Now I want to carry over values of two Drop down lists through Querystring on to my next page.Here is my code to carry over one DDL using QueryString:

Response.Redirect(String.Format("Option1_result.aspx?ddl1={0}", DropDownList1.SelectedValue))

In short, I want to implement a search engine. I pass the search string as a http querystring and my database uses it as a filter in Select. The problem occurs when I enter some non-standard english letters. Let me elaborate: on Main.aspx page, when I click on "Search", a function calls "Main.apsx?search=something". The querystring is passed as a filter to the database which returns values depending on the filter. The database holds correct data at the moment.
After that, I dynamically modify some hyperlinks' url to something like this: hlink[i].NavigateUrl = "Detail.aspx?search=" + base.Request.QueryString["search"] + some integers;. I want users to be able to click on the link to get details on the result. If they click the link, since a new page is now opened, the database has to be refilled (from cache). The same function for filtering the main database is called with a querystring which should be the same as the search string, but somehow it isn't. It looks like something was lost in a conversion or something. If I use standard english letters, everything works fine. I noticed that prior clicking the link the query string had a value like /u0100d for the non-standard letter, but after clicking the link the value had changed to something like /u0ffff. It obviously isn't the same when typing something in the search box and hitting "search", and when putting this search string into NavigateUrl and clicking on it.
On the menu control can one add a querystring to the URL? Can I pass any info using the menu control
