I'm using asp.net and I need to build an application where we can easily create forms without recreating the database, and preferably without changing the create/read/update/delete queries. The goal is to allow customers to create their own forms with dropdowns, textboxes, checkboxes, even many-to-one relationship to another simple form (that's stretching it). The user does not have to be able to create the forms themselves, but I don't want to be adding tables, fields, queries, web page, etc. each time a new form is requested/modified.
1) How do I structure a flexible database to do this (in SQL Server)? I can think of two ways: a) Create a table for each datatype (int, varchar(x), smalldatetime, bit, etc). This would be very difficult to create the adequate queries. b) Create the form table with lots of extra fields and various datatypes in case the user needs 5 integers or 5 date fields. This seems the easiest, but is probably pretty inefficient use of space.
2) How do I build the forms? I thought about creating an xml sheet that had the validations, data type, control to display, etc. as a list. Then I would parse through the xml to build the form on the fly. Probably using css to do the layout (that would have to be manual, which is ok). Is there a better/best way? Is there something out there that I could look at to get ideas?

I have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?
I have a TFS build set up to deploy an ASP.net project to a test server.The build works great, and deploys to the test server fine, but instead of putting it into the Website directory that my IIS webserver is configured for, it puts the build into Website_20100511.6
Why is the date suffixed to the directory name? Is there a way to turn that off so I can publish directly to the Website?

Is there a way to have 2 different menus that have their items populate from 2 separate sitemap datasources?
Currently I have one menu that is populating correctly from one sitemap. I would like to remove some items from this menu and have them in another menu positioned somewhere else on my page. How can I make this second menu populate these items from a seperate datasource?

I would like to state literally that I really do not want to reinvent the wheel, but as you know some times we get some unique "Must-requirement(s)" that will hinder us to re-use the open source codes.I want a proper, flawless and consistent Web Crawler. Basically, I want this Crawler (As a Web app NOT desktop app - Of course based on asp.net and C#) to grab the pages of any website and store them locally (Including resources like images and CSS...etc), download them locally and adjust any resource hyperlinks to point to the locally downloaded resources.
I saw HTTrack (http://www.httrack.com/), and it seems quite excellent, but the problem is that I want this Crawler to be a part of a system which includes other features and process. So, I really can't have this Crawler as an external tool.Main challenges:1) User should be able to specify to which level s/he wants to crawl, which means: User might specify a sub-site and want to crawl everything underneath it and not the upper level. You see ? So, there should be full crawling for the entire site and partial crawling.
2) URLs and how to deal with them? I faced some weird URLs and it was hard for me to identify the actual page because there is no file name. How to handle that? For example: (http://www.blue1.com/en/uk/Travel-info/At-the-airport/Security-control/) this is a URL of a website that is built on EPiServer (.Net based) but as can be seen from the URL that there is not actual aspx page, Therefore, how to deal with such URLs ?I have already started developing a POC using HttpWebRequest class, but frankly I am totally dissatisfied with it. It is inconsistent and the generated static content misses a lot of images and styles. Besides, the threads act up sometimes strangely.I would greatly and sincerely appreciate any input (Approaches, source codes, ideas , links...etc)P.S. I already saw: (http://www.codeproject.com/KB/IP/Crawler.aspx) and (http://www.codeproject.com/KB/aspnet/ZetaWebSpider.aspx).
con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);da = new SqlDataAdapter("Select URL from Table1 where ID =" + Session["USERID"], con);cb = new SqlCommandBuilder(da);ds = new DataSet();da.Fill(ds, "Table1");string pageUrl = ds.Tables["Table1"].Rows[0]["URL"].ToString(); Response.Redirect(pageUrl);
This code working fine..I want to this code working on Hyperlink click Like below
Can anybody recommend how I can build / add a robust photo gallery into my ASP.NET site? I would like the photo gallery to display images based on the results from a database search. I have already built a page with a datagrid which displays a set of results retrieved from a search. Now I would like to turn these database results into a gallery!
I have already looked at [URL] and a few other sites, but am not getting very far. If you consider the above to be a good example, I am currently stuck on several aspects of this project which I would be very grateful for assistance on.

I am working on a portal wich is hosted in Sharepoint 2007. I need to come up with a widget that will display certain messages. The widget to be visible from all pages of the portal.

I want to build a event based calendar .. sorting by mnth,week,day.... also a calendar to display tasks..
For tat i have a masterpage with calendar usercontrol with tasks... and content page with calendar usercontrol with events Now content page displays both calendar with events and with tasks.
Now when i navigate calendar with events ....the calendar with tasks shuld also navigate to same mnth.
for tat i have used public properties in master page to set values to calendar tasks.
and in content page am setting values to properties in master page usign calendar events properties.
am updating the values even on selection changed and visible mnth changed events.
The problem is tat am facing problems with the synchronizing..
i.e if calendar tasks is always having the previous value of calendar events.
I have a requirement to build a form that has multiple steps (there are 12 steps in total). Based on a querystring (eg. t=1), only certain steps need to be in the form. For example, if t=1, only steps 1, 2, 3 and 12 are required so I need to be able to skip steps 4 through 11.
I'm using a Wizard control for this so far but I'm running into issues with the page lifecycle and moving to the next wizardstep and am wondering how people suggest I could better do the above. The crux of what I'm doing is:
- determine form type based on querystring use a Select statement, then create an array of step ID's applicable to the form type
[Code]....
- when a user clicks next, the method OnActiveStepChanged is fired and the next step based on the array value needs to be shown (this is where I'm having issues) [Code]....
This all seems to be working however when the user clicks next from the starting step in the wizard, the next step is blank (ie. no step is rendered).
What I've done may not be the easiest way to acheive what I'm trying to so I'm hoping somebody has a "why dont you just do this?" type suggestion :)
