One of the guys I work with needs a custom control that would work like a multiline ddl since such a thing does not exist as far as we have been able to discover
does anyone have any ideas or have created such a thing before
we have a couple ideas but they involve to much database usage
We prefer that it be FREE!!!
We use a custom modified version of suckerfish at work. DB performance isn't an issue for us because we cache the control.
The control renders out nested UL/LIs either for all nodes in the web.sitemap or for a certain set of pages pulled from the DB. We then use jQuery to do all the cool javascript stuff. Because it uses such basic HTML, it's pretty easy to have multi-line or wrapped long items once you style it with CSS.
Have a look at EasyListBox. I used on a project and while a bit quirky at first, got the job done.
I'm not sure exactly what you mean by multi-line, but if it is selecting multiple elements in a drop down list, see this demo.
If its showing elements that wrap mulitple lines in a drop down, see this demo. You can put a break in the HTML to achieve what you might be looking for. I've used this control in this manner before, so I can confirm it works.
Good luck.

I am trying to create a tree-like structure for a webpage. In my case a user has a set of projects, each project has a set of tasks, tasks can have sub-tasks, and sub-tasks can have their own sub-tasks. So, basically I am looking for an elegant solution to display the tree-like structure using html elements in an aesthetically pleasing manor. Any tips or ideas would be appreciated.
a good place to start would be to make some psudo-code. most people on this website wont give you an entire solution. i have almost no knowledge of html but in all other programming languages the first place to start would be psudo code. also this sounds like you need to make some objects and structure your code around them.
I would leave this as a comment but I'm lacking a couple of rep points. You may want to focus more on the javascript part of building the tree. The HTML is the easy part. Do some searching on jQuery treeview control and see what you come back with. Here's an example:

Very good explanation. You can customize according to your need.
In a page of my school project website there are a couple of divs I would like to be able to control from the code behind.
I know the easiest way to do that is to add runat="server" and simply do whatever, but unfortunately the IDs of those divs have a variable embedded in them, which makes it impossible for me to add the runat attribute to their tags (because it doesn't let me).
The only solution I can think of is to add those divs dynamically from the code behind and then be able to control them while still using that variable in their IDs.
What I wanted to ask is whether there is an easier way to do that, because the above solution would require quite some code editing which is kind of a pain at this point and I'd like to avoid it if possible. In addition, div written in html are much easier on the eye, which is definitely a big plus since it's a school project.
P.S: Yes I have searched before, but none of the answers applied to my question. I know about Request.Form[] but my page doesn't include a form so I'm not sure whether I can use it or not.
Background info: 2 semesters of C#(WinForms), plenty of HTML/CSS skill, brand new to asp.net.
I'm building a site for a friend who's a photographer. It's just a gallery site, but he'd like to be able to update the galleries himself and he's not tech savvy in the least. So I'm using the following approach to the problem:
Using ASP.NET 4 WebForms:
I'm using System.IO to get the names of the folders which represent the "Galleries" and populating a TreeView control for navigation.
When a "Gallery" is selected, I have code that builds a (HTML)list of the image files and populates an UpdatePanel with this list.
As this is all based on the folders/files, I'm building him an secure admin page to upload files to new or existing galleries(folders). He'll also be able to edit(move/delete) the existing files from there.
I got it all to work, which was a nice little victory, but I'm realizing this approach is not optimal, as none of the unique galleries are findable via search engine or even URL; the SEO value is nill; the browser back/forward buttons are useless...
Can you guys/gals recommend a better way to go about this?
Is there a way to modify what I've already done to optimize the project?
I'll gladly start over to do this right.
Thanks
Couple of suggestions, if you are doing this for fun - and want to learn something, consider using ASP.Net MVC instead. Both will work, but doing it with MVC will give you more up-to-date and marketable skills.
Second, unless you really want to write the whole thing from scratch, consider using a package to do most of what you want and then customize it.
Something like this would work quite well: http://www.galleryserverpro.com/ and is open source, free/cheap and well supported.
SInce you are new to asp.net, you can learn a lot by picking thru the open source code and seeing how other people with more experience have already solved the very same issues.
When a "Gallery" is selected, I have
code that builds a (HTML)list of the
image files and populates an
UpdatePanel with this list.
Well, most of your problem is sitting inside this sentence. get rid of the UpdatePanel. When you are making ajax request, you are not able to allow browser history. so SEO, back/forward nav. buttons are always issue with updatepanel.

Hey folks, I'm wanting to write some rudimentary support for detecting hyperlinks in a WPF RichTextBox control. My plan is to use a regex to identify any links and then manually replace them with real hyperlink objects.
However the part I am having trouble with is getting the correct textpointers, etc. once I find a link. For example, I can flatten the entire document to a text string and find links, but once I do that how can I get the proper pointer to the block that needs url-ifying?
Perhaps a better approach would be to iterate over blocks in the document, assuming a url would not span multiple blocks, however even then I have very little experience working with the RichTextBox/FlowDocument object model so any pointers (pun intended) would be helpful. Thanks!

I have a textbox and a button in one page.I want to enter a word in the textbox and click the button. After clicking the button I want to display the name of the web pages containing the word entered in the textbox. So please tell me how to do it? I am using C#.
So you want to create a search engine internal to your website. There are a couple of different options
You can use something like google custom search which requires no coding and uses the google technology which I think we all agree does a pretty good job compared to other search engines. More information at http://www.google.com/cse/
Or you can implement it in .net which I will try to give some pointers about below.
A search engine in general exists out of (some of) the following parts:
a index which is searched against
a query system which allows searches to be specified and results shown
a way to get documents into the index like a crawler or some event thats handled when the documents are created/published/updated.
These are non trivial things to create especially if you want a rich feature set like stemming (returning documents containing plural forms of search terms), highlighting results, indexing different document formats like pdf, rtf, html etc... so you want to use something already made for this purpose. This would only leave the task of connecting and orchestrating the different parts, writing the flow control logic.
You could use Lucene.net a opensource project with a lot of features. http://usoniandream.blogspot.com/2007/10/tutorial-implementing-lucenenet-search.html explains how to get started with it.
The other option is Microsoft indexing service which comes with windows but I would advice against it since it's difficult to tweak to work like you want and the results are sub-optimal in my opinion.
You are going to need some sort of backing store, and full text indexing. To the best of my knowledge, C# alone is not enough.
