Since ASP.NET response filtering and post-cache substitution are not compatible, I need an alternative way of filtering output. Reference: http://support.microsoft.com/kb/2014472Is there any way to change the markup without using response filter?
View 1 RepliesI have a Master Page as well as a standard Web Form aspx file. What if I wanted to dynamically modify the complete HTML markup in an aspx file (perhaps based on a conditional statement - perhaps in a specific content place holder), how would I go about doing this? Sorry I'm coming from a PHP background so this is why I'm asking such a simple question.
View 1 RepliesI'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.
I thought this would be easy and maybe it is but it's eluding me.
In an action filter (MVC 2) I want to add/edit one of the parameters for the type I'm passing to my action method.
I have an action method:
[Code]....
Bar is a simple class for viewData:
[Code]....
In my BarFilter action filter OnActionExecuting method I want to add a value for paramA which is not set by the view so that Bar will be fully populated in my Foo action method. I've tried various methods of adding values to ViewData, ModelState, Model etc. but I always get a null returned in Foo.
I have a need to specify a custom response header from code when my web service is called. I know that from an ASPX page, you can easily modify response headers, but it is not so obvious from withing an ASMX page.
View 1 RepliesI'm trying to create a HttpModule that changes the Response.Filter like so(for this demonstration just set the filter back to itself):
public class ContentTrafficMonitor : IHttpModule
{
public void Init( HttpApplication context )
{
context.BeginRequest += OnBeginRequest;[code]....
Doing so sets the transfer encoding of the response to chunked, rather than using the Content-Length header.If I remove the line where the Response.Filter is set, the response does have the Content-Length header. Our application depends on the Content-Length header, is there any way to prevent this behavior?
In the web app (C#, ASP.NET) I am working on at the moment, the value in Request.Headers["Referer"] can determine things like custom style. I have created a custom page with a drop down menu to test this functionality. So when the selected index changes, the value selected should be set in the Request.Headers["Referer"] then will be redirected (Response.Redirect), the receiving page will then pick up the value in Request.Headers["Referer"] and adjust the styling accordingly. However I haven't been able to set value for Request.Headers["Referer"]. Is it possible at all?
Website 1 sets the value in Request.Headers["Referer"], e.g. www.xyz.com and before doing Response.Redirect to www.website2.com
Website 2 picks up value in Request.Headers["Referer"], in this case www.xyz.com and do what it needs to do, i.e. styling etc.
I need good css for Gridview just like the mac css
can we provide the filter functionality to gridview like the excel filter.
In securing actions/controllers, do I have to create a custom filter or use MVC built-in filter?
To use the built-in attribute Authorize() on an action/controller or create a separate class that inherits the ActionFilterAttribute which has a method (OnActionExecuting) to override and do the authentication there?
In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.
We may assume that no other group in the LDAP has "kuku" in the name.
I need to create a filter which will return all the users which belong to one of the "kuku"s group.
Obviously, using this filter will bring only the head kukus
(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))
How can I use wild card to fetch all users which belong to any kuku?
For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))
I have decorated my base controller with a couple of action filters. They work fine.
One of those filters sets up the request - does things like set the culture based on the domain, etc.
I also have a handful of actions that require authorization using the Authorize attribute.
My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.
The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.
I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.
does a action filter override a controller filter?

I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
View 5 RepliesI have been trying to figure out how to use the Routing features with ASP.net 4.0 WebForms. I added a route to my route collection:
void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
void RegisterRoutes(RouteCollection routes)
{
routes.MapPageRoute(
"about-route",
"about/",
"~/About.aspx"
);
}
In my master page I tried to do the following: <asp:HyperLink ID="asdf" runat="server" NavigateUrl='<%= GetRouteUrl("about-route", new {}) %>'>Test</asdf> I got a compiler error: Server tags cannot contain <% ... %> constructs. What is the proper way to create a route URL in a server control in Web Forms? I also need to include it in the following:
<asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" Orientation="Horizontal">
<Items>
<asp:MenuItem NavigateUrl="ROUTE HERE" Text="Home"/>
<asp:MenuItem NavigateUrl="ROUTE HERE" Text="About"/>
</Items>
</asp:Menu>
Morning all I have frequently used the old
<asp:Label ID="lblWas" runat="server" Text='<%# XPath("FACEVALUE") %>'></asp:Label>
This type of thing. when I first came across it I loved it, i'm using it again today but not quite so simply. I have a number of extra things I would like to achieve.
Apply formatting to the value. Like Text='<%# string.Format(XPath("FACEVALUE"), "{0:c}") %>'>
<asp:LinkButton ID="lnkBook" runat="server" PostBackUrl='/THEATRE/' + XPath("FACEVALUE")>Book</asp:LinkButton>
For option number 2 the URL is not as I would expect, and for number 1 I cannot get the syntax correct if it's even possible.
I have not been able to find something suitable in google. Hopefully what I am trying to achieve is obvious from the example :)
I have an assembly called like X.Common.DLL. There is some resources files for multilanguage app. Let's say it Language.resx Language.en-US.resx....etc.... I have a web application which contains this above dll as reference... So how can I use this resources file in my web applications markup side?
Text="<%$ Resources:Class, ResourceKey %>" is not valid because of "Class" name is in another assembly...
How would it be possible to set text of ASP.NET LinkButton like below:
