    你不可能为一个可变列的DataTable设计一个固定的rdlc报表文件，因为column是动态的，可能是2列，可能是3列，可能是10列，列名也不同，

目前的办法也只能是根据DataSet,动态创建rdlc,然后再绑定到ReportViewer上。不知道还有其他更方便的方法。

下面两篇文章介绍了动态创建rdlc报表，绑定任意Dataset的方式，并结合xslt控制显示的样式外观，感觉还是很不错的

In my previous post about immediate deadlock notifications in SQL Server 2005 I've shown a way to use a try catch block to get the deadlock error.

The con of this method, although it uses best practice for error handling in SQL Server 2005, is that you have to change existing code and

it doesn't work for non stored procedure code. And that IS a pretty BIG con! As is customary in this blog there is a solution to this. :)

SQL Server 2005 Event notifications

Event notifications are a special kind of database object that sen:d information about server and database events to a Service Broker service.

They execute in response to a variety of Transact-SQL data definition language (DDL) statements and SQL Trace events by sending information

about these events to a Service Broker service. There are three scopes for event notifications: Server, Database and Queue.

We of course want a Server wide deadlock notification so that we can be notified of all deadlocks on the entire server

I have to point out that event notification are an awesome use of Service Broker functionality.

Setup

For the purpose of this post I've used tempdb to hold our deadlock event info. Of course this should go into an administrative database if you have one.

Also an email is sent to notify the DBA that the deadlock happened. Thus the Immediate part :)

USE tempdb
GO

-- this procedure will write our event data into the table and send the notification email
CREATE PROCEDURE usp_ProcessNotification 
AS
    DECLARE @msgBody XML    
    DECLARE @dlgId uniqueidentifier

    -- you can change this to get all messages at once
    WHILE(1=1)
    BEGIN
        BEGIN TRANSACTION    
        BEGIN TRY        
            -- receive messages from the queue one by one            
            ;RECEIVE TOP(1) 
                    @msgBody    = message_body,
                    @dlgId        = conversation_handle
            FROM    dbo.DeadLockNotificationsQueue
            
            -- exit when the whole queue has been processed
            IF @@ROWCOUNT = 0
            BEGIN
                IF @@TRANCOUNT > 0
                BEGIN 
                    ROLLBACK;
                END  
                BREAK;
            END 

            -- insert event data into our table 
            INSERT INTO TestEventNotification(eventMsg)
            SELECT @msgBody
            
            DECLARE @MailBody NVARCHAR(MAX)    
            SELECT @MailBody = CAST(@msgBody AS NVARCHAR(MAX));

            -- send an email with the defined email profile. 
            -- since this is async it doesn't halt execution
            -- EXEC msdb.dbo.sp_send_dbmail
            --         @profile_name = 'your mail profile', -- your defined email profile 
            --         @recipients = 'dba@yourCompany.com', -- your email
            --         @subject = 'Deadlock occured notification',
            --         @body = @MailBody;
            
            IF @@TRANCOUNT > 0
            BEGIN 
                COMMIT;
            END
        END TRY
        BEGIN CATCH
            IF @@TRANCOUNT > 0
            BEGIN 
                ROLLBACK;
            END
            -- write any error in to the event log
            DECLARE @errorNumber BIGINT, @errorMessage nvarchar(2048), @dbName nvarchar(128)
            SELECT  @errorNumber = ERROR_NUMBER(), @errorMessage = ERROR_MESSAGE(), @dbName = DB_NAME()

            RAISERROR (N'Error WHILE receiving Service Broker message FROM queue DeadLockNotificationsQueue.
                        DATABASE Name: %s; Error number: %I64d; Error Message: %s', 
                        16, 1, @dbName, @errorNumber, @errorMessage) WITH LOG;
        END CATCH;
    END
GO

-- create the notification queue that will receive the event notification messages
-- add the activation stored procedure that will process the messages in the queue
-- as they arrive
CREATE QUEUE DeadLockNotificationsQueue
    WITH STATUS = ON,
    ACTIVATION (
        PROCEDURE_NAME = usp_ProcessNotification,
        MAX_QUEUE_READERS = 1,
        EXECUTE AS 'dbo' );
GO

-- crete the notofication service for our queue with the pre-defined message type
CREATE SERVICE DeadLockNotificationsService
    ON QUEUE DeadLockNotificationsQueue 
                ([http://schemas.microsoft.com/SQL/Notifications/PostEventNotification]);
GO

-- create the route for the service
CREATE ROUTE DeadLockNotificationsRoute
    WITH SERVICE_NAME = 'DeadLockNotificationsService',
    ADDRESS = 'LOCAL';
GO

-- create the event notification for the DEADLOCK_GRAPH event. 
-- other lock events can be added 
CREATE EVENT NOTIFICATION DeadLockNotificationEvent
ON SERVER 
FOR DEADLOCK_GRAPH -- , LOCK_DEADLOCK_CHAIN, LOCK_DEADLOCK, LOCK_ESCALATION -- ANY OF these can be SET
TO SERVICE 'DeadLockNotificationsService', 
           'current database' -- CASE sensitive string that specifies USE OF server broker IN CURRENT db
GO

-- check to see if our event notification has been created ok
SELECT * FROM sys.server_event_notifications WHERE name = 'DeadLockNotificationEvent';
GO

-- create the table that will hold our deadlock info
CREATE TABLE TestEventNotification(Id INT IDENTITY(1,1), EventMsg xml, EventDate datetime default(GETDATE()))
GO

-- clean up
/*
DROP TABLE TestEventNotification
DROP PROCEDURE usp_ProcessNotification
DROP EVENT NOTIFICATION DeadLockNotificationEvent ON SERVER 
DROP ROUTE DeadLockNotificationsRoute
DROP SERVICE DeadLockNotificationsService
DROP QUEUE DeadLockNotificationsQueue
*/

Testing

For testing you'll need to open 2 windows in SQL Server Management Studio

-- tun this first to create the test table 
USE AdventureWorks
IF object_id('DeadlockTest') IS NOT NULL 
    DROP TABLE DeadlockTest 
GO
CREATE TABLE DeadlockTest ( id INT)
INSERT INTO DeadlockTest
SELECT 1 UNION ALL
SELECT 2
GO
----------------------------------------------------------------
----------------------------------------------------------------
-- run this in query window 1
BEGIN TRAN

UPDATE DeadlockTest 
SET id = 12
WHERE id = 2

-- wait 5 secs to set up deadlock condition in other window
WAITFOR DELAY '00:00:05'

UPDATE DeadlockTest 
SET id = 11
WHERE id = 1

COMMIT

----------------------------------------------------------------
----------------------------------------------------------------
-- run this in query window 2 a second or two 
-- after you've run the script in query window 1
BEGIN TRAN

UPDATE DeadlockTest 
SET id = 11
WHERE id = 1

-- wait 5 secs to set up deadlock condition in other window
WAITFOR DELAY '00:00:05'

UPDATE DeadlockTest 
SET id = 12
WHERE id = 2

COMMIT
----------------------------------------------------------------
----------------------------------------------------------------

-- run this after the test to see that we have our deadlock event notification saved
USE tempdb
SELECT * FROM TestEventNotification
ORDER BY id

We can see that this setup works great. Because we have subscribed to the DEADLOCK_GRAPH event we can see the same information

as if we had traced it with the SQL Profiler. Of course this kind of setup can be used for any kind of event that is supported.

• 树形结构的DataGridView:Customizing the DataGridView to support expanding/collapsing (ala TreeGridView)     DataGridView


 

TreeGridView 修正版本：

Some people reported problems actually running the TreeGridView sample, so I've recompiled it on an RTM build machine (previously I was using the latest internal VS build). You can get the new version (that also includes release & debug binaries prebuilt) here: http://www.windowsforms.net/blogs/markrideout/TreeGridViewRebuilt.zip

• 单元格中同时显示文本和图标

The DataGridView control does not have any built-in support for showing an icon and text in the same cell. Through the different painting customization events, such as the CellPaint event, you can easily display an icon next to the text in the cell.

The following example extends the DataGridViewTextColumn and cell to paint an image next to the text. The sample uses the DataGridViewCellStyle.Padding property to adjust the text location and overrides the Paint method to paint an icon. This sample can be simplified by handling the CellPainting event and performing similar code.
