How and Where to store search parameters in MVC application

Posted By:      Posted Date: October 14, 2010    Points: 0   Category :ASP.Net

I am working on a railway web application and I have following layers:

ASP.NET MVC 2 (Presentation Layer) 
Services Layer 
Repository Layer 
Database & External Web Services as data sources (Using Entity Framework for Database) 

I pass Domain Entity Objects from Repository to Service layer and thinking of passing View Models from Service to Presentation layer. Website would require a login and after successful login I have to present a search screen with basic search (as default option) and option for advance search. Once user fills the search criteria I have to gather data from DB & Web Services and present the results to user. User would select a particular Rail option and would move on to other additional options page BUT they should be al

Error in / Application after adding employee search in webpart


Hello everyone,

I am working on sharepoint 2007 and I was editing the webpart of the software and after adding the predefined employee search table, the server has crashed while trying to access the server remotely with the following error message:

Error in / Application

However, while trying to login locally I have no problem and can easily login.

What will be the course of action in fixing this error.

Also the site is complaining of an invalid certificate even after adding an exception.

Any help would be greatly appreciated.

Thank You,

Chris Stanko

Creating an database search application in VS C#

Hello everyone, I wish to create a C# application that will have a form and a text box where I can enter a text, and then ask the application to search if this text exists in a database. If it exists, I want all the information associated with this text to be displayed in a datagrid view or list box. I am able to create a database in SQL Server and I can connect to my database from VS 2005 C#. If this is possible, how do I go about it? Many thanks in advance.

SharePoint 2010 Search Service Application: "All Content" scope contains 0 items?

I've encountered a nasty bug in our setup. Our Search Service Application manages to crawl all content just fine. However, the scopes don't work. We've got a total of 570 items currently in our crawl database. 350 of these are of class 'People', and appear in the 'People' scope. The remaining 220 items should appear in 'All Content' as part of the intra (sites, documents etc), however the 'All Content' scope reports 0 items. I've tried the following: -Creating custom scopes (still 0 items) -Recreating the Search Service Application twice -Tried different accounts as the content access account. -Ensuring that the content access accounts do have 'full read policy' -Checked the crawl log for successful content (such as sites and documents). However, despite my efforts I still get 0 items for 'All Content'.  Has anyone else encountered this problem, or do you have any recommendation for us? Currently I don't see any other option than to reinstall everything.

problem rename sharepoint 2010 search service application admin database

Hi all, i have a problem that hopefully someone has an answer to.  i am not too familiar with sharepoint so please excuse my ignorance. we have sharepoint 2010 on a windows 2008r2 server.  everything seems to work fine.  but as you know, the default database names are horrendous.  i have managed to rename all of them, except for the "search service application" admin database. the default is: Search_Service_Application_DB_<guid> the other 2 databases (crawl and property) were renamed without a problem. we are following the article from technet on how to rename the search service admin db (http://technet.microsoft.com/en-nz/library/ff851878%28en-us%29.aspx).  it says to enter the following command: $searchapp | Set-SPEnterpriseSearchServiceApplication -DatabaseName "new database name" -DatabaseServer "dbserver" however, i get an error about identity being null.  no big deal, i add the -Identity switch and the name of my search service application.  but the real problem comes the error it throws:   Set-SPEnterpriseSearchServiceApplication : The requested database move was aborted as the associated search application is not paused. At line:1 char:54 + $searchapp | Set-SPEnterpriseSearchServiceApplication <<<<  -Identity "Search Service Application" -DatabaseName "ShareP

Access denied to Search Service Application

I just "upgraded" my installation of SharePoint 2010 Foundation with Search Server Express 2010.  During the installation, I was able to access and configure the Search Service Application. However, a day later, I cannot access the application management page: I get an access denied error.  I am the farm administrator, so supposedly I am supposed to have access to the management page.  I've also tried adding my login to the "Full Control" group of the Search Application; it gives me the same error.  It appears that the only account that can access the administration page is the service/system account.  Obviously this would not be ideal. I've tried looking around for logs to see if anything is amiss, but there appears to be nothing logged. What gives?  How do I fix it?

Search Service Application missing in SharePoint 2010

I installed SharePoint 2010 (Enterprise edition), enabled Enterprise features but it is missing Search Service Application when I look under Central Administration > Application Management > Manage Service Application.   When I click on New it doesn't even list "Search Service Application".    When I goto Upgrade and Patch Management > Check Product and Patch Installation Status, it tells me that "Microsoft Search Server 2010 Core" was Installed.  Under Manage services of server, "Sharepoint Foundation Search" is started.  Does anyone have an idea why the "Search Service Application" is missing and how can I install it?

Secure Service Store and custom web application.

 Hello All,  I have a problem for which I would like to use the Secure Service Store.  I've searched for similar solutions involving the SSS but I've not had any success yet.  Maybe I'm missing something obvious or going about it the wrong way.   We have an external application (actually, a number of external applications) we'd like to embed in our SharePoint site using an iframe or the Page Viewer web part.  The embedded application uses a custom forms based authentication scheme and I want to prevent the situation where a user has to log into our application then log into the embedded application.  Is there anything available the help post the credentials from SSS to the custom application?  The only think I can think to do is write some code that mimics a post to the login page of the embedded app and, if needed, write a stripped down or simpler login page for the embedded app to make that easier.  For my immediate task I have quite a bit of control over the source of both application and could write custom code on both sides if I had to, but I'd rather have a solution that only involve configuration or, at most, custom code on the SharePoint side.  Thanks,  Brandon

Search Server Express 2010 - Access Denied when attempting to manage Search Service Application or P

I first noticed this error with the Search Service Application when I was no longer able to use the search portal, but have since noticed the issue with the PowerPoint Service Application.  When I navigate in Central Administration to either the "Farm Search Administration" or the "Manage service applications" pages and attempt to manage the "Search Service Application", I get this error: Error: Access Denied  Current User You are currently signed in as:  WHEELERS\MyUserName   Sign in as a different user    I have tried removing the service application and re-adding it, changing the application pool to running under an existing application pool as the farm administrator, as another application pool with the same identity as the primary web application, and as another application pool running under the SP-SearchService identity. The big recent change with SharePoint, aside from fixing the previous issue where I was incorrectly using CNAMEs with Kerberos, was to switch the main web application to claims authentication. That site correctly works with claims based authentication and Kerberos.

Trying to build a custom application to crawl SharePoint Search

Hello,      I have been tasked with building a custom application to develop a report dynamically based upon a search ran in a SharePoint site using user-defined keywords. What I need the application to do is this: 1.) Access the results of a search, and do a full fidelity save of each item. 2.)  If the item returned is a document in a library and it has other versions associated with it, access the meta-data of those other versions and group those results with the item found in the search. 3.) Store the results in XML (probably the easiest), and build a custom display for reporting purposes. If anyone has any advice on how I can accomplish this, I would be very grateful, Thanks!

The Best Place to store Settings for Web Application.

I want to create an Application Setting or Control Value for "Application Run Mode", which will indicate if the application is in Testing Mode or Live Mode. So I have created this Enum Type: Public Enum AppRunModeType Live Testing End Enum and, this will be used inside the the Web Application to determine if the application run mode, and hide/show some UI Controls accordingly. This Setting "Application Run Mode" is not a User Setting, it is a setting to be controlled by the developer who is deploying the application. Where is the best place to store this value ? I am thinking there are 2 places: 1. In web.config "appSettings" secting, 2. Or in Project Properties Page/Settings Section. If I choose to store it in web.config, then, I will not be able to have Strong Type Access to the value like the Enum type, and I have to convert from Enum Type to String and vise versa. If I choose to store it in Project Properties Page/Settings Section, then I cannot do that, becuase my Web Application is not a Porject and I cannot find this page there, or I will have to convert the Web Application to a Web Application Porject, and this is a Long Story. Also, How I can access My.Settings object from the Web Application ? Appreciate if some one could point me to the right direction and the best way to hanlde such requirement.

Sharepoint Search and Secure Store Service not working

Hi There I am having issues with a few Sharepoint Services When I try to search for a document on any SharePoint site, I recieve an "Internal Server Error Exception". However when I checked the log files, I couldn't find any error messages matching with the given correlation ID. The search was working 2-3 weeks ago. Also 2 weeks ago, I started receiving warnings in the Health Analyzer saying “The Security token service is not available”. I am wondering if the security token service breaking down is related to the search issues, and if so what suggestions I could try to fix this issue. I am also unable to access the secure store service. In Central Administration->Application Management->Manage Service Applications, I try to click on the Secure Store Service, but there is no Proxy attached to the service, and I receive a message “No Secure Store Service Application Proxy ID was found”. When I check the Logfile, I receive these errors: 08/10/2010 11:11:32.94               w3wp.exe (0x18E4)                                      0x0ADC SharePoint Foundation     &nb

How to delete incomplete Search Application?

I messed up a parameter value in my PowerShell script to create a Search application.   It is partially created and trying to activate.  [ Admin and Crawl databases created with associated registry entries, but query and proxy were not created.]  I see reference on the web for a CancelActivation method that can be used from VB or C#, but I have not been able to find anything in PowerShell to help.   Attempts to delete the search application via the GUI or remove it with PowerShell just sit there until the nightly recycle of the application pools cancels the process. This is Search Server 2010 Express so all components are on the same server.  I have been able to successfully create a second search application so the users have search functionality, but I need to be able to remove the incomplete one.   Any help would be greatly appreciated! Central Admin search management page says "did not finish loading" (and topology and crawl status just have the spiny spinning forever) Event log entries occur about every minute: Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchServiceInstance (fba8ced3-8939-4463-8159-de4fea83a618). Reason: The search application '578b7ed5-520a-41f3-abd4-194bc622a827' on server CACGIS09 did not finish loading. View the event
