Is there any tutorial out there on how to write a FileUpload in asp.net with a progress bar? i cant find any of if there is a free component that would also work!
I found a few different options out there. I haven't used any of them, but I will most likely look into the 3rd option here in the near future.

I have used NeatUpload on one of my projects in the past. I have not had any issues with it since I got it working.
The software is free and covered under LGPL License which is great if you're going to use this for work.
The FileUpload control that ships with ASP.NET just transfers the file with the request payload. Therefore the only progressbar you'll get with it is the one at the bottom of your browser. You'll have to go with a 3rd party solution.

I'm not asking for detailed code for this question, but rather solid direction to learn how to do it myself. There appears to be many methods and directions so just looking for a headstart from someone experienced.
I have a simple file upload control. I want it to operate as an ajax upload, no page-refresh, and if I'm understanding correctly I need http handler that grabs the image and deals with it behind the scenes.
So I need to create a custom control, a new file upload that allows me to set some properties, such as... Path for the image, prefix for three different types (I.e. thm_uniqueimagename.jpg, med_uniqueimagename.jpg, lg_uniqueimagename.jpg) and an option to either KeepOriginal="True/False".
I'd like to see a progress bar while the image is uploading as well. A fantastic example would be a post on Facebook and how you can upload an image.
Right now I'm stuck with a standard upload control that has full post-back/refresh and it's just not nearly as attractive.
I'm just now learning VB... So basically if you can say... Read this tutorial, then do this, then do this... that would be greatly helpful. Just overwhelmed with what to do first, and how to put it all together.
Platform: Windows, .net, etc.
Thank you for any advice.
If you want a better user experience, then I suggest you investigate some solutions like the following:
ASP.NET AJAX file upload
AjaxFileUpload.
Note: If you read the documentation for the ASP.NET AJAX AjaxFileUploader, it says that it requires HTML5 for the progress feedback; otherwise it shows a spinner. So if progress feedback is a necessity and you cannot fully support HTML5 in your target browsers (i.e. older versions of IE; IE6, IE7, IE8, etc.), then you should look into the options below.
Custom HTTP module
NeatUpload is a free option.
Silverlight/Flash option
SWFUpload is a free option.
Asynchronous chunking option
RadAsyncUpload - Telerik's ASP.NET AsyncUpload is a pay option, check website for pricing.
I have looked over other questions on this website, but am yet to find a solution that meets our requirements.
We need a Timeline control that makes it possible to display some HR information (distribution of consultants) over longer periods of time (months). The screenshot below illustrates the requirement.
We currently use a Windows-based component from a third party. We need this application to be visible on the web, including display on iPad devices. Are there any controls on the market that support this functionality?
I haven't explored many of the options yet, but I'm working on an application that uses DayPilot Lite (the open source version) from http://www.daypilot.org/ to display a calendar. The scheduler control looks like it could do something like what you're looking for.
maybe Telerik Scheduler

Here's one from codeplex that might work...

There's also the "viewer" approach you could take -- for example, you could put a view of Visio or MS Project, etc. in a window on your page. Not sure how interactive it would be, but if your need is just for view-only, it might work.

Have you looked at Google Charts? Specifically you could, perhaps, use their Annotated Timeline.
Google charts have some serious issues if any asp.net project is deployed in IIS.
I just wanted to ask a question about uploading files via AJAX. I have researched on the web and found many articles on doing this. I am using ASP.NET 2.0.
I am probably going to go the jQuery route on this one, but I'm still unsure, I just need some feedback. Bacause my aim is to create an admin page for my client to add new products to his site when my client wishes to, so my client wants a simple file uploader and a multiple file uploader.
The first question is which is the best AJAX File Uploader to use?
The second question is how many files can you upload via AjAX, are there limits to how much you upload with different techniques ie. using jQuery or SWFUpload or using IHTTPHandler?
I would be grateful for your feedback.
Thanks.
I actually had to do this for an item here at work. To keep things rather simple, I went old-school and used a hidden iframe to do the file transfer in the background. There may be more fancy ways, but this worked for me. Also, there's no headaches when Adobe pushes out a bad update.
It was a while ago, so I can't remember the nuts n' bolts of the top of my head, but here's an article that seems to be using the same idea:
http://www.openjs.com/articles/ajax/ajax_file_upload/
This is a subjective question, as there is no one solution fits all for your application. The right answer is the uploader that meets your business needs. Limitations, if they exist, are set per whatever component you decide to use.
First off, I'm sorry if the title doesn't explain this very well.
I'm looking for an asp.net control that works similarly to the Visual Studio toolbox's auto-hide. In other words, when not needed, it can be "unpinned" and will slide off to the side of the screen. When needed, it can be opened and pinned to stay in place. I'd rather not do it myself using javascript if a (free) control already exists. Does anyone know of such a control? If not, has anyone implemented this type of functionality using a js library with good results? Any pointers?
Thanks in advance.
Edit:
The collapsiblePanel might work, I don't have any experience with it, but it's open source software from CodePlex.
I don't know of any free ASP.Net controls. But if you want to get it working using javascript you can do so with jQuery.
This post on StackOverflow shows how to get the autohide feature working
We use Telerik's RadSplitter. It is exactly what you are looking for.
Unfortunately, it is not free. But it worths checking out since their licensing is very flexible.

I need to make a client able to drag and drop images into category-folders in an ASP.NET 3.5 web-app.
I was hoping that an option existed, that was almost as easy to use as the Reorderlist from Ajax Control Toolkit, and where I did not have to look into JQuery or similar handcoding.
What are your recommendations?
Similar questions have been asked before, like this 6 months ago...: ASP.net AJAX Drag/Drop? where MooTools is recommended, but 6 months is a long time in the ASP.NET/Ajax world, so maybe a better and even simpler option exists now?
Commercial components are also an option - well up to 200$ anyway.
My experience with the Reorder List in the Ajax Control Toolkit, as with many other 3rd party providers, is that most of them don't seem to be worth the effort. Definitely try them before you buy.
Unfortunately a lot of the samples/components out there are all too client-based and always seem to fall short on real-world uses and the sorts of interaction you need with ASP.Net applications (e.g. handling postback). Dragging a div around isn't that complicated, but that's all a lot of examples do. If your needs don't exactly mirror their offering try something else.
The Manning book ASP.NET AJAX in Action is a good reference on code for performing drag and drop. It uses Microsoft.Web.Preview, but this hasn't been updated in quite some time which is a worry. I have created a pretty good drag and drop UI with MS's PreviewDragDrop, it does work cross-browser, and it's pretty easy to code. Preview DLL's aside, the Manning book is great for understanding Microsofts AJAX API.
However, since jQuery is going to be shipped and supported with Visual Studio, I would recommend using it over anything else in a vain attempt to future-proof yourself.
A final piece of advice is never outsource your core competency. If this page is a core part of your offering you're better off implementing it yourself using library code like jQuery or Microsoft.Ajax rather than relying on a 3rd party component. However, if it's just a minor part of your site, then go ahead and use 3rd party controls.
Ref: My Version of Microsoft.Web.Preview.dll is 1.1.61025.0.
i have been very very happy with telerik's treeview control and use it for almost any asp.net application which needs a treeview drag and drop.
they allow free development licenses (not production though) so i guess you should give it a try. go to www.telerik.com and have a look
This is another Mootools suggestion, but you might find the Mif.Tree plugin useful. It's an MIT license. There are also code examples for each of the demos and API docs.

After spending 4-5 painful days of hacks, double-hacks and hacks to get around other hacks, I have come to the same conclusion as you. Especially the reorderlist from the ajax control toolkit drove me to the very edge of insanity.
It seems to me there is no real way around learning JQuery and simply doing the stuff myself. I used to shy away from doing client-side code, but with AJAX so much code has moved away from being just serverside.
JQuery has just been moved to the top of my personal study program.
Jquery has drag and drop controls.

Maybe that will help...
