I am in the process of having a site designed that has an ajax application imbeded (online gallery) in one of the pages. I have been told that it is not possible to link directly to a category within the ajax application from other pages on the site.

View 1 Repliesi create example using Northwind database so i create a new website and add new ADO.Net Entity Data Model (.edmx) called Northwind.edmx and i add Categories and Products table inside this (.edmx) file
and add new ADO.Net Data Servuce called "ADODataService" and add it as WebReferences called NorthwindService
so i add new web page and drag DropdownList and Gridview as i want to bind Dropdownlist to all categories and when i select category from Dropdownlist bind Gridview to all Products related to this category
so my code
[Code]....
and my code
[Code]....
so when i select category from Dropdownlist nothing happen :(
also you will find commented code in method BindCategory whuch is not work also.
I'll try to explain as simple as I can in text what my problem is. I don't see any other way to make my issue clear.
I have a GridView that uses an ObjectDataSource.
The ObjectDataSource has an DataObjectTypeName defined, so I pass/get complete objects or list of objects to/from the data access methods.
The objects I'm working with, let's say we work with Book objects, contain a Title and a Category, BUT the Category is an object itself. When the Select method is called, we get a List of Book objects, which is perfectly displayed, overridden ToString method in the Category objects within the Book objects.
The problem I face is that I can't find a way to update the category in my GridView. What I did already accomplish is:I used a template field in the GridView for the Category so I could use a DropDownList for that field in Edit mode.
I bound the DropDownList to another ObjectDataSource that gives me a list of CategoryObjects.
So when I enter Edit mode... the row shows a nice ddl with the available categories. It even selects the right original category.
So far so good... but when I want to save my new selection, I get an error that a string (the selected category in the ddl) cannot be converted to a Category object (that's what the Book object, that is going to be used for the update, expects).
I am working in a project that is a musical website. I want to display the web page with all categories I have. In my database , named Category_Master, I have two fields like Category_Id (which is a primary key ) and Category_Name. I have generated category_Id with NEWID() function. The category_Id is not supposed to display on the web page. But, i have to select Category_Name and according to that , I have to get the category_Id. If I am using Static connection with SqlDataSource, i am able to make visible=false property so that the category_id won't be visible. But , at that time, I can't write code to Select the category_id of the selected index.
If i am using disconnected approach, I filled the dataset with the Category_Master, and binded it to GridView. But, at that time, I can't hide the category_id from the user. I want to select category_id by clicking on the category_name with out displaying category_id ..?
I am using VS 2008. I have added Ajax controls to the toolbox but i am not able to use them..
What could be the problem? i do not get any error message.

View 5 RepliesImagine a Web Forms application with routing.
A clean page name like:
[URL]
Might have an underlying of URL of:
[URL]
If a user enters [URL] into a browser, I need to redirect to [URL]
Is this possible to do?
I can't work out a way to do this as the routing engine is not executed for a physical page and in the page.aspx Page_Load method I have no way of knowing whether the URL was entered directly or was the result of a route.
I have been asked to develop an ASP.Net application which will directly connect (store and retrieve) to the ACT! databse already functional. I am new to ACT and looking for a starting point to integrate it with ASP.Net application. In particular I am looking for answers to the following questions:1. What database technology is used by ACT? Is SQL Server? In that case, I should be able to connect just like any SQL Server database?2. Is there any class library or API for .Net from ACT which will help achieve this?3.
View 1 RepliesI am using VSTS 2008 + C# + .Net 3.5 + Silverlight 3.0 + ASP.Net to develop a Silverlight application (a video media player) in browser and the function is simple, just use MediaElement to play a remote video file.The remote server is Windows Server 2008 + IIS 7.0 + IIS Media Bit Rate Throttling Control.Since the request media URL can be discovered (e.g. from traffic sniffer), and I want to know how to prevent from download directly from the Url? i.e. I want end user to use my Silverlight media player application in browser to play the file, prevent them from download to local directly. Any easy and quick solution or reference code/documents?
View 5 RepliesI need to create some links to the Twitter search page.
In my first example 'link1', that works fine, when you click the link you go to the twitter search results for 'wc2010'.
However, in my second link I want to search for the hashtag+wx2010, which is how data is related/grouped on Twitter. My second link always just redirects to a user called 'wc20210' which is not what I want. How can I create a link to a hashtagged word on Twitter?
string link1 = "<a href='http://www.twitter.com/search?q=wc2010'>Link 1 to Twitter</a>";
string link2 = "<a href='http://www.twitter.com/search?q=#wc2010'>Link 2 to Twitter</a>";
Response.Write(link1.ToString() + "<p>");
Response.Write(link2.ToString());

View 1 RepliesThere are two user controls, which are built dynamically.
In the first control, I am adding a link button, and trying to attach a click event on the same. But the event is not fired.
Actually the main goal is, when the link is clicked, based on which one is clicked, I need to show second control (the values on the new controls are based on the first controls link button that is clicked).
If I use javascript, I will need to use ActiveX or is there any other way to instantiate the second control using javascript

I'm trying to convert an ASP application to a .NET one. In the old ASP application methodology we have a "users" database with all our users and is indexed by an auto-increment integer which is used across our database (~25-30 tables) relationally. I'm recreating the tables from scratch, so no need to worry about merging data. Let's assume we just have a large relational database that we want to connect to the .NET security model.
Now - with .NET, there is the concept of members and roles being handled for you. I took a look at the aspnet_Users table and it shows a GUID for members I created using the ASP.NET Configuration tool.
Basically I need advice on how to link the ASP.NET user's login to my custom database. Any tutorials/links are welcome, I'm not afraid of reading!
It would be great for the Context.User.Identity.Name to store the auto-increment integer PK as well because that could be used in all of my SQL queries to grab information for given users.
p.s. I'm trying to write it as an MVC2 application with a lot of Linq to SQL to keep it all strongly typed and awesome.
I have a table with records that has delete links. Basically I followed the NerdDinner tutorial for that part in MVC. But I don't want to have the confirm view, I'd rather have a confirm dialog, and then if confirmed let the HttPost action method delete the record directly.
I have something working, but being new to both MVC and jQuery, I'm not sure if I'm doing it right.
Here's the jQuery:
I found the function for making the link POST instead of GET on the internet: `$.post(this.href); return false; And I'm not sure what the "return false" part does. I tried to modify it for my needs with a callback and so on, and kept the return part without knowing what it's for.
Secondly, the action method has the HttpPost attribute, but I have also read somewhere that you can use a delete verb. Should you? And what about the RedirectToAction? The purpose of that was originally to refresh the page, but that didn't work, so I added the window.location.reload instead in a callback in the jQuery. Any thoughts?
The Delete action method calls a couple of helper methods because it seems with the Entity Framework that I use for data, I can't just delete an record if it has relationship dependencies. I had to first delete the relationships and then the "User" record itself. That works fine, but I would have thought it would be possible to just delete a record and all the relationships would be automatically deleted...?
I know you're not supposed to just delete with links directly because crawlers etc could accidentally be deleting records. But with the jQuery, are there any security issues with this? Crawlers couldn't do that when there is a jQuery check in between, right?
My client wants to pass values through the query string, but they don't want the query string to be displayed in the browser's address bar. The values being passed are for tracking purposes. I know that postback doesn't happen after you click on href link.Is there any way I can get the value out of the query string without displaying it in the browser's address bar? I think this may be impossible, but I may be wrong; I'm hoping to see if anyone has any answers.
View 3 RepliesI have made two web application, both application deployed on differnent server with database. one have SQL and other Oracle.
server 1: Web application 1/SQL Database.
Server 2: Web Application 2/Oracle Database.
I have given link of Web application 2 on web Application 1. its means single sign on logic. I have login in web application 1 and click link of web application 2, when I click on link I want to authenticate to user in oracle databse (on server 2) if user is valid or not.
I have a webservice I need to call via a link. The webservice returns a pdf document and takes a document Id as a input parameter.Under normal circumstances I could have the link call some code in the code behind which in turn calls the webservice.
However the difficult part about it is I can't add code to the code behind. The reason is it is for some CMS users who want to know what links to add to the page which will download the pdfs. I can only add the link to the aspx page.
I'm reading an ASP.NET book that says you can't use Profile if you select Web Application when you start a project. It only run under Web Site.
Are there any alternatives for Web Application? Or do you need to build your own Profile system.
