ADO.NET :: GridView Paging / Unsupported Overload Used For Query Operator 'Distinct'?

Aug 27, 2010

The issue is two fold in my ASP.NET Web Application. I need to use a custom Distinct() via LINQ to SQL, and then assign thevar as a DataSource to a GridView.

If I use the custom Distinct that implements IEqualityComparer,I get "Unsupported overload used for query operator 'Distinct'" exception. but if i somehow get past this, i get "The data source does not support server-side data paging" exception on GridView.DataBind(). here is the code:

[Code]....

And here is the IEqualityComparer:

[Code]....

With this code I get Unsupported overload used for query operator 'Distinct'. BUT! if I change the code to

[Code]....

, I get System.NotSupportedException: The data source does not support server-side data paging

C# - Linq To SQL Mplementation Of Query Operators Except The Contains() Operator?

Mar 26, 2010

I have a local collection of record Id's (integers).I need to retrieve records that have every one of their child records' ids in that local collection.
Here is my query:

public List<int> OwnerIds { get; private set; }
...
filteredPatches = from p in filteredPatches
where OwnerIds.All(o => p.PatchesOwners.Select(x => x.OwnerId).Contains(o))
select p;

[code]...

I am getting this error:Local sequence cannot be used in Linq to SQL mplementation of query operators except the Contains() operator.I understand that.All() isn't supported by Linq to SQL, but is there a way to do what I am trying to do?

C# - GridView Paging Using Linq Query As Datasource?

Aug 27, 2010

I am looking for a way to do paging with a GridView when i set the datasource at run time using a linq query. here is my code:

ETDataContext etdc = new ETDataContext();
var accts = from a in etdc.ACCOUNTs
orderby a.account_id
select new
{
Account = a.account_id,
aType = a.SERVICEs.FirstOrDefault().SERVICE_TYPE.service_type_desc,
name = a.SERVICEs.FirstOrDefault().service_name,

[Code]....

But that works well when you use a datatable but not with linq. If I add a rebind in the event, it has to requery 7000 records which can be a little slow. Does anyone know how to fix the paging when using linq like this?

Databases :: Syntax Error (missing Operator) In Query Expression?

Mar 8, 2010

I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should. There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.

Forms Data Controls :: GRIDVIEW Paging Problem Using SQLDATASOURCE With ODBC Query

Feb 16, 2010

I'm using VS2008 to write a web app. The page has 3 inputs (select date from calander, and items from two dropdownlists). User will be able to select any of the three or nothing. I start with a "select * from ... and append a where stmt to my select; depending on the user's choices. Once the user has selected (or not) they will click a "get info" button. That passes the select command to the SQLDATASOURCE, where it successfully returns what was requested. If I have PAGING enabled (perferred because there could be MANY rows returned), the first 10 rows return with the appropriate page numbers. When a page number is picked (ie. 2 or next), the page reloads and the query reruns but regardless of the original query; the rerun query selects everything. Obviously, this will not work.i'll even ZIP my code and email it to "you"; if needed.

DataSource Controls :: Using Visual Studio 2008 Query Builder And Am Trying To Pass A Value To A Parameter That Uses The IN OPERATOR?

Jun 3, 2010

I'm using Visual Studio 2008 Query Builder and am trying to pass a value to a parameter that uses the IN OPERATOR.Here is my sql from qb:

SELECT COURSE_TITLE, INSTR_NAME, ADMIN_UNIT
FROM vwHRIC_EC_ContractSummary
WHERE (ADMIN_UNIT IN (@ADMIN_UNIT))

The trouble I am having is that if the parameter @ADMIN_UNIT contains more than one value such as (8X, CV) that the query doesn't return any data. If I run the same query with only one value such as (8X) it works fine.I have tried different formats like (8X, CV), ('8X', 'CV'), (8X; CV) but none have worked.I ran this same query in SQL Server Management Studio and and it returns data no problem but can't get it to work in Query Builder for my aspx application.Does anyone have any experience with this problem and how did you correct it?

Select Distinct And Include Non-distinct Columns?

Apr 20, 2010

I would like to select a distinct query based on three fields and display the rest of the fields. For example,

I have firstname, lastname, address, city, state and zip, but I only want to use the distinct on these fields first and last name. However when i use the distinct function I get a distinct on all the selected rows. I just want to distinct firstname and lastname and display the other fields. for example,

Mary Smith New York
Mary Smithy New York
Mary Smith Maine

I would like the result to be:

Mary Smith New York
Mary Smithy New York

I don't care about Mary Smith Maine, because i am only using the distinct for "Mary Smith" firstname and last name and showing the city.

SQL Server Connection Client Tried To Connect To An Unsupported Version?

Jul 21, 2010

We recently launched a new web site.there are roughly ~150 users active during peak hours.During peak hours,we are experiencing an issue every few minutes,the exception text is listed below.

System.Web.HttpUnhandledException:
Exception of type 'System.Web.HttpUnhandledException' was thrown.
---> System.Data.SqlClient.SqlException: The client was unable to establish a connection because of an error during connection initialization process before login.

Possible causes include the following:
the client tried to connect to an unsupported version of SQL Server;
the server was too busy to accept new connections;
or there was a resource limitation (insufficient memory or maximum allowed connections) on the server.(provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)

Our data access layer calls various DataTableAdapters using the following syntax.

EDIT

Yes, da is the name assigned to the DataTableAdapter. There is no connection.Open() because the DataTableAdapter takes care of all that, right?

using(TheDataLayer.some.strongly.typedNameTableAdapters.suchAndSuchTableAdapter da

[code]...

The connection string looks something like:

<add name="MyConnectionString"
connectionString="Data Source=myDBServerName;Initial Catalog=MyDB;User ID=MyUserName;Password=MyPassword"
providerName="System.Data.SqlClient" />

I'm trying to rule the problem being in Code.Is there anything "simple" that can be done to minimize this issue?

C# - Editable GridView Distinct Drop Down Lists

Jun 3, 2010

I have a simple app I am messing around with its a basic Master/Details layout. The details panel is actually a tab panel and on one of the tab panels it has a GridView. Within that grid view it shows the "current" in database information with all cells as read only. I then have an add button that inserts a row into the GriView and allows the user to enter some information. The first item in my GridView is a DropDownList, which is populated from an ObjectDataSource. This drop down is basically my unique index and there can only be one selected value per GridView.

What is the best way to remove the values from the list that are already in the GridView? Do I just need to remove the data source and add a OnDataBinding method that iterates through the grid view and generates a valid list of values? I can't use a service method because if the user adds two rows they would have the option to insert duplicates description types.

C# - Attempting To Force Gzip Compression On A Page Using GZipStream But Browser Says Using Unsupported Compression

Aug 4, 2010

I'm tring to implement what Steve Souders discusses [URL] about forcing gzip compression

I've got a module that's running this:

[code]....

CompressionUtils.GzipSupported just checks for the 'accepts-encoding' header while
CompressionUtils.GzipSupportedExplicitly and CompressionUtils.GzipNotSupportedExplicitly check for the cookie saying whether the browser really can read gzip

But when I load a page in Firefox I get this error:

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

and in Fiddler it shows that the content-encoding header has been added but the content hasn't been compressed
