I am using CSLA 3.0 and .Net Framework 3.0. I am working in Siliverlight application references to WCF service and WCF service references to CSLA classes. My application runs successfully, Insert and update running successfully but sometime I am getting this error of Timeout in DataPortal.Update. When I debug the code Error comes at
DataPortal.Update failed (System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Have you attempted to time the command when run manually?
The default timeout is 30 seconds, you could try to set the CommandTimeout property to be a higher value (or for testing purposes, set it 0 for infinite timeout).
Please give me some hint of code where and in which file to set CommandTimeout property.
Somewhere within your code, I assume that there will a line where the commandText for the commandObject will be set.
The code may look like this with in your DataPortal_Update()
Using cm As SqlCommand = cn.Connection.CreateCommand
.CommandText = "[hrm].[mergeNote]"
.CommandType = CommandType.StoredProcedure
.CommandTimeout = 60
Is it possible to change the default CommandTimeout value of the SqlCommand object via the config file? Our connection string has a timeout value in it which is not honored by the SqlCommand. I don't want to have to manually change every use of the SqlCommand object in order to increase my default timeout from 30 to 60.
One easy solution is to use a factory object/method to create your command:
public static class CommandFactory
public static SqlCommand GetCommand(SqlConnection cn)
var result = cn.CreateCommand();
// initialize command here
Then just use this method to create your commands app-wide.
Of course maybe not so easy if you already have a lot of code in your codebase...
We are getting our SQL timeout errors with the following message: DataPortal.Fetch failed (Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.)
Is it possible to update the code to be able to tell what object is actually failing?
The inner exception might provide you with that information. There's usually a lot of info deeper in the exception tree.
