Sqldatasource updating event to check using the debugger

(By default, the Query String Parameter takes the value of a query string variable and submits it to the database without any validation.) If the value is not acceptable, you can cancel the update by setting the events after the database operation completes.

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 Sql Data Source control uses the , which means that update operations overwrite any existing values in the record without determining whether the record has been modified by another source.

I ran the stored procedure within sql studio management and it works just fine.

The first 3 parameters being passed are correct "@arg Permission ID","@arg Permission Level","@arg Permission Name" which is what the stored procedure accepts but with wrong values all are empty. If you have defined fewer parameters in your Update Parameters collection than what is being passed to your SQL or Stored Procedure, then you will get this error.

Therefore, you cannot directly cancel the Update database operation by calling the Cancel method on the Db Command object that is exposed by the Sql Data Source Command Event Args object.

You can, however, cancel the database operation by setting the The following code example demonstrates how to display data that is retrieved from a Microsoft SQL Server database in a Drop Down List control and update the record using a Text Box control.

Parameter names and values are based on data fields bound to a control or alternatively on parameter objects that you define explicitly.

Parameters from a data-bound control include both values for the data operation and for key values to identify a specific row, as defined by the Data Key Names property of the bound control.

You can create explicit definitions to specify parameter order, parameter type, and parameter direction as well as additional parameters other than those based on fields bound to a control.

An example of this would be an output parameter that returns a value automatically generated by the data source such as an auto-incrementing primary key or a date-time stamp.

I have the SQLData Source and the parameters specified on the *It's using a Stored Procedure.
