AJAX is the big thing...but it seems (to me) that with Silverlight 4 Microsoft has offered a really robust method for creating UI interfaces for the web. I'm wondering - what is the future of AJAX? Do AJAX and Silverlight complement each other or will Silverlight replace AJAX, etc.?

does Visual Studio come with a video player component build in? or do I need to make a video player?
how to use Silverlight to play audio from local ASP.NET folders?
View 1 RepliesI am having the hardest time figuring this problem out. I have a Silverlight 4 application that loads audio and video files from URLs. The URLs are the same domain as the application is hosted on and it works great for video.The URLs are actually asp.net mvc controllers that are responsible for reading the file from a shared location on and the server and serving back a filestream. The URLs look something like this:http://localhost:31479/CourseMedia?path=omnisandbox1ILMSShare2Demo-Fire+BehaviormediaDisclaim.wma&encrypted=False&id=00000000-0000-0000-0000-000000000000
If I put the URL directly into the browser the file loads and plays in windows media player just fine, and if I use a separate test silverlight project to load the url it also works, but for the life of me I can not get it to work properly in my main project.This is the routine I use to actually do the source setting:
protected void SetPlayerURL(MediaElement player, string url)
{
if (player != null && url.Length > 0)

i am new to web development and i am learning Asp.net. i was the other day thinking and i came up with this question. i searched the web but all the answers i found were old so my question is , can silverlight4 replace Asp.net? I know this question sounds crazy . but let's think for moment we use ASP.net to talk to a server.to Create files there ,to talk to a database etc. SilverLight can do the same thing ,right? OK,you might say that if I built a web site using SilverLight then not all users out there can access it. but apparently SilverLight supports IE,FireFox Safari and googleChrome so i guess this isn't an issue anymore. so what do you think ,can silverlight replace asp.net?
View 6 RepliesI am having trouble accessing an embedded Silverlight 2 media player in an aspx page from Javascript and was hoping someone might offer some insight on what's going on.
What I want to do is fire a javascript event on the client when a button is pressed to change the Silverlight media player media source and then play the newly selected file.
I found what seemed like a pretty straightforward example on the silverlight.net site that looked like this:
[Code]....
However, when I run it, I get an error "undefinedObject doesn't support this property or method".
I've confirmed that the client-side id I am using is correct, and I have tried using document.GetElementByID in place of $find (which is what I use elsewhere on the site successfully; my javascript kung fu is weak and I'm not precisely sure what the difference
might be) but it still doesn't work. It all seems like it should work as it was presented in the example, but I only get that error.
I 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 would like also to know the way to have an embedded video in my site that will not have the play buttons and play again and again. Is there a way to do that??
View 2 RepliesAt page load I made several tabs Enable = false.
If a button is clicked I want to set Enable = true.
The problem is that this doesn't work, they stay not touchable. How come?
RelatieTabContainer.TabIndex = 2;
RelatieTabContainer.TabIndex = 0;
I've created my first Tab control (yay me!), and everything has gone really well up until I tried to incorporate a UpdateProgress control into it. Basically, my container contains three tabs, each with a seperate report. Each report takes 5-10 seconds to load, so I thought it would be nice to flash up a "Loading Wait" logo to let them know it's being processed. Everything is compiling cleanly; however, when I click on a tab nothing happens. The reports loads as they always have, but the UpdateProgress control never kicks in with it's loading message.
I've been researching for the past day to the point that my brain now hurts. Different things that I have/am trying:
My entire tabcontainer is in an UpdatePanel. I have previously also tried putting the individual tab panels in seperate UpdatePanels, but this did nothing.I've tried both directly referencing my UpdatePanel and using no references in the UpdateProgress control. Neither changed anything.I've created a button to create an UpdatePanel postback. I've moved the button all over the place, inside the panel, outside the panel but referencing it via trigger.
I've tried using the asynchronous triggers in various ways. I created a very simple web application with just an UpdatePanel, UpdateProgress control, and button (but no tabcontainer) -- and this worked fine. I just wanted to verify I didn't have some other root issue with my setup that could be causing an issue.

I am a tech writer and am working in visual studio creating tooltips for an ERP site. Originally we were using the Jquery tools from flow player[URL] but these did not agree with our asp elements. Specifically the drop down and check boxes. It also caused odd display features with our buttons. On one page the display looked great until an autogenerate button was pushed. Then, all of the formatting went away. So my question is, is there something else that's free that can allow me to style my tooltips and work well with ajax?

Let's say I have a rolegroup as follows:
<asp:LoginView ID="lvDoSomeStuff" runat="server">
<RoleGroups>
<asp:RoleGroup Roles="RoleOne,RoleTwo">
<ContentTemplate>
...
</ContentTemplate>
</asp:RoleGroup>
</RoleGroups>
</asp:LoginView>
Is there a way I can make it so that a user must meet RoleOne and RoleTwo to satisfy the RoleGroup? By default, if a user is in either of the two roles, they will be granted access. I know I can do this via the code-behind, but I'd prefer to be able to wrap some content template with this markup instead of having to wrap it in a panel and hide the panel programmatically.
want animation that whenever user input data in form and click on submit then there play animation please wait
View 2 Repliesi want to implement asp.net role provider to assign users over my LAN to roles and have my asp.net intranet app implement security based on roles.
i dont want to use VS to manage this with the built in tools but rather hand this off to users to manage themselves. i want an admin folder with a page(s) for admin roles to be able to create/edit roles and manage users in roles... this way an admin can add a domain user (MyDomainUsername) to a role such as ProojectManager or Tester or Developer... and users wont need to contact me for these tasks...
can anyone provide me a link (or some sample code) to some sample i can use to admin roles and users over a LAN in asp.net with c#?
I have a multi level application that I am developing and need to block multiple rows from being joined. I know how to hide one role but I cannot figure out how to hide multiple.

I've been trying to replace my dropdownlists with ajax ComboBoxes so i can apply css in ie.
I can't seem to apply any css to the items in the dropdownlist. Here is my css:[Code]....
I've tried putting font styles in every class but it does nothing. The font in the actual text bar is styled correctly.
Also i've noticed the dropdownlist doesn't display all the items in it. Only the top 2.
using the ajaxControlToolkit requires the ToolkitScriptManager, but then i get the message: "only one scriptmanager..." the problem is, i cant find any other scriptmanager in the whole solution, so it should be somewhere in the parent pages. how can i find/get/replace this scriptmanager-object?
View 3 RepliesI am currently working on a website with a Tab Container with roughly 5-10 tabs. I would like to have an Admin tab that is disabled to all users except those who are assigned in an Admin role (I have 2 roles, Admins and Customers).

View 6 RepliesSo part of my web app centers around this very important form which is used to create a form. Its like google docs form. The user keys in a type (checkbox, textfield, numericfield) and a label and slaps it into the system, and it generates a form somewhere.
Its a little more complex than google forms, the field types are complex and theres a lot more to that form (It happens to be a form generator for a finance plan)
The app is asp.net, I was thinking of using jquery and jquery's own ajax methods to post the data, but I think it would just turn into a very hairy situation, I then thought silverlight, but Ive never done silverlight before but I am an experienced .net guy.
So what do you guys think, will silverlight be too tough for a first timer for this kinda thing? Or should I stick to jquery. Plus points for silverlight is its an inhouse lan app and this particular page will be used by people with very high bandwidth.
Also I'm on .net 4 btw.
I am using the ajax toolkit calendar extender control with the asp.net button for the postback event. the functionality is after selecting the date, clicking on the submit button will call the button event. now I need to obtain the same thing without clicking the button and on the date selection. ie, on selecting or closing the calendar control the postback event has to fire. how too obtain this? calendar and the button are placed in the user control.
View 8 RepliesI have a web page devoloped in visual studio 2008.I have 4 dropdowns and a repeater in the page.based on the selection(search criteria) from the dropdowns the repeater value will change and one dropdown selection will bind values to the other dropdown also.Since the page is causing a lot of postback we decided to implement ajax here.I am yet to learn ajax.which ajax control replace dropdowns?
i have already server side code written on all dropdowns.Please give me a good solution which i can implement in less time and reuse my code.One more update: i have a master page used in the project.I am using update panel of ajax which does not work if i use master page.(That means all the dropdown controls and repeater i put it in update panel.But still page postback occurs.)In a normal page(without master page) it works?
Newb question: what is the standard practice for assigning roles to newly signed-on members. Is it usually manual or is there a way of automatically assigning roles. Being completely new to this, I am confronted by the issue of my site having three different roles that new members could fall into, but am unsure about how to assign each a role. I can't imagine having to go through the process manually if I have thousands of members.
View 6 RepliesI have run into a problem where I need to remove certain items from collections that seem to only have get all functions.
My Idea is to get the full collection and then remove the unneeded items. Then take that new collection and bind it to whatever I need.
For example How do I get all the roles except administrator?
Roles strRoles = Roles.GetAllRoles()
RoleList.DataSource = (Roles) roles; //Roles.GetAllRoles();
RoleList.DataBind();
or How do I get all users but say user123
MembershipUserCollection users = Membership.GetAllUsers();
UserList.DataSource = users;
UserList.DataBind();
