Sqldatasource updating event to check using the debugger
You can add a handler for these events to manipulate, reorder, or validate parameters for a statement before it is executed, as well as to cancel the command.For example, if you are using a events after the database operation completes. And yes, this is the last time I will be using Sql Data Source - It seems everyone recommends a different approach (DAC?I have a Sql Data Source that is supplying data to my Grid View.Parameters are used to send values for insert, update, and delete operations to the data source.Parameter names and values are based on data fields bound to a control or alternatively on parameter objects that you define explicitly.event to perform additional initialization operations that are specific to your application, to validate the values of parameters, or to change the parameter values before the Sql Data Source control performs the update operation.The connection to the underlying data source is not yet open when the event handler delegate is called.
I'm stumped if that doesn't work as you've basically got the simplest-possible example.
Optimistic concurrency is a database strategy that protects against losing changes at a data source in scenarios where multiple users are manipulating the data at the same time.
The , which means that update operations overwrite any existing values in the record without determining whether the record has been modified by another source.
The actual syntax of the SQL statement depends on the schema of your data and on which database you are using.
The statement can include parameters if the data source supports them.
