I don't think that it is possible. Because decision will be taken by the browser, and ASP.NET can't control it. Why do you need such an option ?

Atleast the basic formats like word, excel, power point, pdf docs should be supported, is there any mechanism to do this

AFAIK, NO. Operating system will be having file extension mappings, which maps file extension to applications which can read that. When a file is opened through browser, browser looks for this application mapping and loads it on the specified application. It is decided by the browser where to load the file, and how to show it. So you can't control it.

You can't call a JS function from app_code. JS works on client and classes will be executed on server.

You can make use of HTTPContext class. It provides static methods to get access to the current page object. Using that you can give RegisterClientScript() which registers a client script to the current page. See the following code.
System.Web.UI.Page p = (System.Web.UI.Page)HttpContext.Current.CurrentHandler;
p.RegisterClientScriptBlock("JSName", "JSScript");

If you just want to force a server side event to get fired through then you can achieve it like this:
__doPostBack('<%= yourcontrol.ClientID %>','');

I am making a web service, and need to get the request/response objects associated with the call. How can I get these objects from C#? I expected there to be something like HttpRequest.GetCurrent(), HttpWebRequest.GetCurrent(), or WebRequest.GetCurrent(), but I don't see any such methods. Searching on google for "C# Request Object", "C# current Request Object", "get request object C#", etc., have all turned up articles related to asp using a C# code base. I'm guessing there is some object with a static property or method to get the current request/response objects, but I can't find what object it is. Can someone please let me know what object I need? Thanks,

Hi All,

I just doesn't make since to me that it would work fine on my dev machine, but not in production. I have taken the following steps to trouble shoot.
Since both sites are on the same server I made sure I could ping the web service url from the server. That works fine. Just in case I modified the host file using the Loop back ip 127.0.0.1 to make sure. Still no good.
I have been reading some articles on line and one said that you should not have charters like _ in you service name, so I removed the _. Still no good.
Not too sure what to do. Any help is greatly appreciated.

Hi,
I new started with Linq and VS2008 and created a new Web-App automatically with DataContext and LinqDataSource, GridView and DetailView.
But, because I want to place the var LinqQuery into the CodeBehind-File, I code the Var LinqQuery by hand and not by designer.
It works well inside GridView and DetailView for New, edit, Delete and Paging. 
But for Sorting I find no way to use SortExpression and SortDirection inside var LinqQuery
private string GridViewSortDirection{
get{return ViewState["SortDirection"] as string ?? "ASC";}
set{ViewState["SortDirection"] = value;}
}
private string GridViewSortExpression{
get{return ViewState["SortExpression"] as string ?? string.Empty;}
set{ ViewState["SortExpression"] = value;}
}
protected void gvMain_Sorting(object sender, GridViewSortEventArgs e)
{
GridViewSortExpression = e.SortExpression;
GridViewSortDirection = e.SortDirection.ToString();
int pageIndex = gvMain.PageIndex;
CorydorasDataContext db = new CorydorasDataContext();
var FiArtsQuery = from p in db.FiArts
where p.Name.StartsWith(txtSuch.Text)
// orderby p.SortEspression SortDirection
orderby p.Name descending xxxxxxxx hier are the problem
select p;
gvMain.DataSource = FiArtsQuery;
gvMain.DataBind();
gvMain.PageIndex = pageIndex;
}
I hope anybody can help me?
Thanks

Not sure what your problem is... I use the following.
public void AddJavascript(string javascriptUrl)<br />
{
HtmlGenericControl script = new HtmlGenericControl("script");<br />
script.Attributes.Add("type", "text/javascript");<br />
script.Attributes.Add("src", ResolveUrl(javascriptUrl));<br />
this.Page.Header.Controls.Add(script);<br />
}<br />
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
AddJavascript("~/Scripts/ImageRight.js");<br />
}
I didn't get any requirements for the signature

Well then all I can say is to try FireBug in FireFox. It might help you figure out why the object is missing. Not sure that's worth your time since you already have a working solution, but that is what I would do.

Guys,
We've spent the entire day looking at why our code kept open several Oracle socket connections on the web server. After a while, we saw that the .Close function was almost never called. Yeah, we thought, this is it. So I made a quick and dirty ASP.Net page with the proper dll's, a button that opens the connection and one that closes it... The socket stays open...
Earlier that day a colleague recommended to use GC.Collect(), which we tried in the Global.asax file (at Session_end). It didn't work. Now, just to make sure, I tried also a GC.Collect() right after the Close (so in the button event handler)... Lo, the socket connection dissappears. Move the GC.Collect() to the Global.asax; no avail anymore...
So why doesn't it work in Global.asax and it does work in the Page itself? (I also tried to put the connection in a Session variable, but that didn't work either)
thanks.

Instead of calling GC.Collect, you might want to use a 'using' structure:
using (conn = new SqlConnection())
{
}
On leaving the using block, dispose is called on the connection, which should free up any used resources.

|
|
|

good idea, but as it is an old website (not written by me  ) I will not run through 20 000+ lines of code to check for using. Besides, the original coder opened stuff in one function and used it in another one  .
but thanks though, I appreciate the effort

This does't make sense...
You open the connection during the first postback. If you do not close the connection during that same postback, it is going to remain open. I don't see how you could close the object from the code of another button. ASP.Net does not work that way.
So if your application is leaving the connection open after a postback, you have to go back and fix the code. All 20,000 lines of it.
Calling the garbage collector is not going to do anything for you...
