After the release of MVC 2, i have started to check and play with the new features. But i couldnt understand that why do i need to use PUT or DELETE verbs? I have searched about it and read some articles but i couldnt get it. What is the main purpose of DELETE and PUT (and do they have any advantages rather than using a GET or POST method) even though i can handle all of the requests with GET and POST.
View 5 RepliesThere are few verbs that we see in HTTP , like GET , POST , OPTIONS ..ETC ." my question is how to use the verbs while I am using my browser ... or do I have any option to use them?
View 2 RepliesI'm attempting to configure a webdav server example application [URL] to run on IIS6 (Win2003 Server). The application runs correctly on my dev machine (Win7, IIS7.5). When I attempt to map a drive to the DAV share, several requests are issued, including one OPTIONS request and two PROPFIND requests. In Fiddler, I see that these are transmitted correctly. However, the response is always the content of the default page on the site. If I look at the IIS logs, the requests are logged as GETs instead of OPTIONS or PROPFIND. UrlScan is disabled, but I went ahead and added OPTIONS and PROPFIND to the list of allowed verbs (since I'm running out of ideas).
View 1 RepliesI have a restful controller that has your standard REST HTTP Verbs: Get,Post, Put, Delete. The problem I am having is that although my controllers are decorated to accept these verbs, when I execute my REST action, it can only hit my Get and Post methods. I have the attributes on top of the controller actions: HttPut, HttpDelete, HttpPost, and HttpGet. I also have the the override method in my forms: @Html.HttpMethodOverride(HttpVerbs.Put) When I submit my form, I get a 404 error from IIS 7.5, saying the static file handler couldn't find the resource. Strangely the same forms work in Cassini, so I think it is something in IIS7.5's setup.
What do I need to do to get IIS 7.5 to handle REST verbs like PUT and DELETE with Asp.Net MVC 3? I have already removed WebDAV and have looked through the handlers but the ones I am modifying seem to do nothing. My current setup is Asp.Net MVC 3, IIS7.5 on Windows 7.
When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.

Background:
We are using the Facebook API and receive back URLs for profile image thumbnails. Unfortunately the protocol is restricted to just HTTP and it doesn't support HTTPS. The page on our site that hosts the thumbnails is always delivered via HTTPS, and if we use HTTP for the thumbnails the user will receive security warnings from their browser.
Solution:
Build an HTTP Handler that "passes through" the image from the Facebook URL, but allow the handler to be called via HTTPS. Before I started coding I thought I could something like this:
Response.OutputStream = WebRequest.Create(FacebookUrlForThumbnail)
but I ended up having to save the image to an object in memory than write the image to the Response.OutputStream using the image save function.
Current Code:
[Code]....
This seems inefficient but I can't find a way of using the HTTP Handler as I orginally intended. Is there way of accomplishing the goal without creating the image memory and just "passing through" the call?
clear my concept What is HTTP module and HTTP Handler and how does they work while page requesting???

View 2 RepliesHow do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?
Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.

I am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.
View 5 RepliesI have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.
<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
