Multiple Methods Of Searching Same Sql Table?
Jan 26, 2010
First off I'm a week into asp so apologies in advance for silly questions! I am looking to connect to a SQL database table and allow the user to filter the table based on a search box on the asp page. I have written a sql query with a parameter in the where clause, a bit like this:
select col1, col2
from table
where col1 like @my_parameter
Then I pointed the parameter to a textbox on my asp page, and this seems to work quite well. However, I would now like to add an additional search facility which would be a dropdown list. This would be sourcing all the unique values from the col2 in my table abve (there are only about 10 possible values here). But I don't want users to be able to use both of these searches at the same time.
So the bottom line is I would like to offer two methods of filtering the same data table, which search on different columns of the data table. Then the results should populate the same results table, but the user must only be able to use one search method or the other.
I have done a bit of research but couldn't find anything along these lines (I think it is becuase I don't know the words of the things I should be searching for!). I did find information on a standard postback event or cross page posting - not sure which of these (if any) is the best to use for a beginner?

I want to query an SQL table using some Web controls to provide the parameters for filtering the records in the table. Results are displayed in a GridView.
I have a TextBox with an ID of "keyword" where the user may enter one or more keywords. I'd like to search 2 columns for instances of these keywords.
I also have a DropDownList named "category" that lists categories contained in a "category" column of the table.
I have a dataset with a TableAdapter for the table I want to search. Got it working fine with the DropDown List but not sure how to proceed with the TextBox and keywords.
What SQL query should I use? The user may not enter anything into the textbox, they may enter one word, or multiple words.
This is where I am now:
SELECT * FROM tablename WHERE category = @category AND ??

I want to select data from a table where the user can search by 3 options; date, keyword, and type. The date will always be either today or a user chosen date. The keyword can be null or something the user inputs. The type will be chosen from a drop down and can be all or a specific category. I know how to search the date, but the other two create complications. I have created a stored procedure trying to figure this out:
[Code]....
Is there a way to say if the keyword is null then don't use it as a search criteria. If that is possible then type can use that same logic I suppose.

We have a database with a lot of information about Persons. I won't post the entire database structure because it is too big, but it looks something like this:
Person
ID
Name
Street
City
State
Country
Language
LangCode
Language
Interest
ID
LastChangedBy
LastChangedOn
LocalizedInterest
InterestID
LangCode
Description
PersonInterest
PersonID
InterestID
Now, this is just a small example. In our database, we have about 8-9 localized tables (like Interest) a Person can be linked to. A Person can have multiple Interests, a Person can have multiple Jobs, a Person can have multiple Educations, a Person can have multiple Experiences, I have to build a search function. Let's say you enter "tom" as the search term. This should give a list of all Persons with "tom" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables.
If you enter multiple words to search for (eg. "tom php"), it should give a list of all Persons with "tom" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables AND "php" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables. At the moment there are about 4,500 records in the Person table and if I do an outer join of Person with all the tables I have to search, there are about 1,300,000 records and 40-50 fields to search in.
How should I approach this problem so that performance will be acceptable? The client expects "something like Google" in terms of speed and ease of use. We're using MS SQL Server 2000 and ASP.NET 2.0. The search functionality has to be added to an existing application and changing the technology or database structure is not an option.

I am trying to create a form in MVC C# that will allow a user to input a Last Name, First Name, Department, Year and click a Search button that will bring back a list of employees based off the inputted search criteria.My problem is allowing multiple search textbox criteria into one search button. I am able to hardcode values into an html actionlink like below and it works but unable to grab the values from the textboxes.
<%= Html.ActionLink("Results", "Results", new { lastName = "Smith",
firstName = "", dept = "", year = "2008" } )%>
I would really just like to have four textboxes and a search button to bring the list back from the database.

I have three text boxs
1.txtname
2.txtage
3.txtmobile
and one dropdownlist
1.ddlcity
for search client information.
My requirement is when search button click the client information will bind in gridview based on data filled in textbox and dropdown list.
The difficulty is user can enter any combination for search. E.g.
1.age only
2.name and city
3.city only etc.

I'm building a new ASP.NET MVC application (in C#) and one of the requirements is to create a new database of members. For this, we'd need roles to manage the different types of members and profiles to manage the additional metadata attached to each member. So far so good, just use the standard MembershipProvider, RoleProvider and ProfileProvider provided as part of the .NET Framework.
However, the catch is that I'd like to allow different authentication methods. I'd like Accounts and Login Credentials to have a one-to-many relationship (one account can have a number of login credentials attached). A user for example, might have both an OpenID and ActiveDirectory account attached to their account.
However, after experimenting with a few ways we opted for the MembershipProvider route (explained how it was achieved as an answer below).
It appears to be something that is achieved on quite a number of sites, yet a search on here doesn't return anything solid to play around with.
EDIT: After looking around for a good period of hours overnight and this morning - I'm still not convincinced that butchering a single MembershipProvider would have been the easiest option. Does having multiple MembershipProviders give the same effect?
BOUNTY EDIT: With no responses, I am assuming that there is no more optimal solution that the one I posted as an answer. Is this really the case? I'm offering a bounty to try and see if anyone has any further thoughts on this and whether there are better alternatives.
BOUNTY ACCEPT EDIT: I think that WIF is the answer as accepted below, for a .NET 4 release and maybe other versions as it probably works with 3.5. Other than that, maybe a butchered MembershipProvider or adapted one may still be relevant.

I need to run 5 different WCF methods but within a transaction. Is this possible in WCF? How can I do this in WCf, if it's possible?
The WCF methods will be called from the web service client, which could be an ASP.Net app or Winfoms app.

it may sound a bit newbish question.We have a web service that comunicates with the database and exposes web methods that enables the application to access the database. Each method does only one operation (Insert, Update or Delete). What I need to do is create a transaction that will be consisted of multiple calls to the database, meaning multiple calls of more then one web methods. Can I do that? (I read that if the web method does not throw exception - or ContextUtil.SetAbort() is not called - the transaction will be commited automatically when the web method finishes executing, which I don't want to happen because I want to call another web method in the same transaction, and then manually commit the transaction)

In one of the applications I am working on, there are two basic functionalities included: Create and Update. However, there is a need sometimes to add custom code, so I thought of extending the code by allowing 3rd parties to write and embed their own code:
OnCreating
OnCreated
OnUpdating
OnUpdated
Is there a way to enable the above across multiple assemblies? MEF might help here?

My requirement is to show a page with multiple filters to apply to grid data.
Suppose we are talking about Orders and an order has the following attributes
public class Order {
public int OrderID
public DateTime OrderDate
public DateTime ShipmentDate
public int OrderTotal
public int OrderStatus
}
Inside the jqgrid object I am showing all the attributes except the OrderStatus
The requirement is to create a view that has the jqGrid on the left part a panel on the right
Inside the right panel the user will see a list of checkboxes that represents every possible OrderStatus value and he want to search using both methods (for example selecting the checkbox "Shipped Orders" and then filtering the grid with Amount greater than a value)
I have already configured the advanced filtering (multiplesearch:true) inside the jqGrid object and I am able to create complex filters combining fields and logical operators.
how I can submit even the data from the right panel when the user press the search button?
Update 1:
Preamble: Oleg sample is fantastic but unfortunately does not fits requirements of my customer :(
@Oleg: I do not understand why you think that:
If the data are outside of the grid you will be show the order details on the right pane only for selected row. So the user will have not so good overview of the data.
maybe my description was not so clear but I am not going to show any order detail. To better clarify my requirement I have modified your sample to show you the desired final UI which is as in the following image:
The customer want to filter the data in the grid using two methods or both together:
Using the multiplesearch facilities provided by the grid itself (thanks for the workaround mention) Using the custom Search Panel (the one with the checkboxes on the right) provided
From a functional point of view the requirement is very easy to express: When the user click on a checkbox or make a search using the native multiplesearch I should post values to the server including also the checkboxes state.
To summarize I should:
Add the checkboxes state when a post is made through the native multiplesearch
Add the current multiplesearch state (if any) when the user click on a checkbox

I've created a Gridview in my aspx page, which is referenced in two separate methods in the code-behind file. When I try to run the page, I'm getting a 'does not exist in the current context' error.After a bit of poking on the internet, it seems that I might need to declare the gridview at the class level if it's going to exist in more than one method... problem is, I do that and it disappears from the page altogether.I'm obviously not doing this right - I'm declaring it like this (abridged version):

I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()

I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.

how to get multiple row from table in asp.net using c#?

Tables:
WORKORDER and CUSTFIELD
Fields:
WORKORDER = WORKORDERID
CUSTFIELD = WORKORDERID, CUSTFIELDNAME, CUSTFIELDVALUE
There are multiple different type of name/value pairs. I want to specifically return the custfield value where custfield name is "INCIDENT", and the custfield value where custfield name is "NETWORK" all for the appropriate WORKORDERID
I've tried a few different ways and just can't grasp how the linq is supposed to go to get the results I want. I can get an incident value, or network value, but not both.
I have the proper association set up in the dbml so both of these work to get the single value:
var b = from i in edcwdv.WOCUSTFIELDs join p in edcwdv.WORKORDERs on i.WORKORDERID equalsp.WORKORDERID where i.CUSTFIELDNAME.Contains("INCIDENT") select new { i.CUSTFIELDNAME, i.CUSTFIELDVALUE, p.WORKORDERID };
var incident = from wo in edcwdv.WORKORDERs orderby wo.WORKORDERID where wo.WOCUSTFIELDs.CUSTFIELDNAME.Contains("INCIDENT") select new { wo.WORKORDERID, wo.WOCUSTFIELDs.CUSTFIELDVALUE}; So essentially i want to pull the value for each of the fields, INCIDENT and NETWORK
