You are putting a physical file name in the session variable. That is useless in a web page, you need the virtual file name.
Do you need to keep the file name in the session for some reason? Otherwise you don't need a session variable to put the value in the page. A plain member variable in the page works just fine.
Experience is the sum of all the mistakes you have done.

Hi guys,
I'd like to gather some ideas on how to implement a menu navigation trail feature.
What I am referring to is the feature present on some websites when you go down into the menus.
ie. this site, if you go to http://www.codeproject.com/sqlrs/ the menu trail shows: All Topics, MFC/C++, C#, ASP.NET, .NET, VB.NET >> SQL Reporting Services

this looks like a linked list. so you have to go to top level node until you don't get any (the top level/parent is null) and display all of them. all parent nodes will be displayed as a link and current node will be displayed without any link

I guess this approach would work fine if the menu is created dynamically from a DB, so I can pre-populate the linked list.
Thanks!

Hi,
i'm a beginner in asp.net programming and web for that matter,
and in need of some help.
i use an unknown amout of tables that i need to view, lets assume the connection string and select query are entered by the user.
i need in the page_load or somewhere to create a dataset and set the gridview to it. the grid view is a static control on the web form.
now i am using:
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("con str");
SqlDataAdapter ad = new SqlDataAdapter("select str", con);
DataSet ds = new DataSet();
ad.Fill(ds, "test");
con.Close();
this.Controls.Add(data);
theGrid.DataSourceID = data.ID;
theGrid.DataSource = ds;
theGrid.DataBind();
}
this works, but each click/change that causes a postback will call page_loaf again. i tried to define the ds variable as private var of the class, and then put the 3 first lines in an if (!postback) {...} statment.
didn't work, the vars are recreated on each post back.
what is the solution for this?
how can i create a grid that will be saved without re binding it?
(and if i don't add the ds to the form as a control, it just doesn't bind)
help!!!
thanks, koren.

Yes, because when a request comes in to the web server a page is created, it is populated, it is rendered to the clien browser, the page on the server is then destroyed. The server does not keep a copy of all the pages currently open by the various browsers that are linked to it. So when a browser makes a new request the server has to go through the whole sequence all over again.

Hi,
I am having the strangest problem when trying to use a standard Javascript popup. When using the popup on my local machine the addressbar is hidden correctly but when I upload the page to the server, the address bar is shown.
The code I've tried so far consists of variations of the following:
window.open("pagename.html","GamePreview", "scrollbars=yes, resizable=no, location=no, toolbar=no");
thanks
ps: I've noticed the same thing happening with the code project preview window.

try this
<br />
window.open("pagename.html","GamePreview", "status=no,directories=no,location=no,menubar=no,toolbars=no,scrollbars=yes,resizable=yes");<br />
you can set the values to yes or no as required

The Gridview at least supports paging.

I have a real simple web page, when I debug it it works fine,when I copy the files to my internal server and try to run the page I get an error.
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'XXX.Global'.
Source Error:

What is this error and how do I go about resolving it? Do I need to re-build somethign onteh server or have it re-build something?

I have a problem with a child window using the parent's FORM to do a submission/post to open a new window. This is being blocked by IE7. This is happening when accessing an external website that is not listed in the IE7 pop-up blocker allow list.
If the current page does a FORM submission/post to target "_blank" then this is allowed and a new window pops up. However, if the new child window calls opener.top.document.someForm.submit(); then this is blocked.
I am developing a website and I don't want to tell users how to setup their popup blocker. I wish to find a way to get around this problem. Does anyone know how to allow a child window use it's parent window's form to do a submission/post to target "_blank"? without being stopped by IE7 pop-up blocker?

the parent window contains the main form with all the hidden input elements for posting & also correct URL, etc. the child windows know nothing about the URL nor does it have any forms of it's own. the child window would call the parent window's form to submit... to OpenDoc.asp to open a new child window. I do not want the child window to open another child window within itself. Only the parent window should be allowed to open many child windows.
Get what I mean?
I even tried writing a auxillary function in the parent window to openDoc()... and the child window calls this openDoc in the parent window. But this still gets blocked. It's like as if IE7 knows the original caller.

Try reading the guide on how to ask questions. What control ? Is it a server control ? If it's not visible, it may not even be on the page, and even if it is, what do you expect it to do ?

you can't. XML is a format for text data. It can contain an image, in a CDATA section, but unless the XML is also HTML and contains an img tag, and is shown in a browser, an XML viewer is never going to show an image, it's going to show the text inside the XML. Even then, you need an img tag to an external image, not to any image inside the XML
