I have been scratching my head on this for awhile now. I have a website that I have local RDLCs that are populated by an ObjectDataSource which is pulling in TableAdapters from an Xsd data source. I am getting the below error after a report takes longer than 30 seconds to run:
An error has occurred during report processing.
Cannot create a connection to data source 'xxxxx'.
Exception has been thrown by the target of an invocation.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
The wait operation timed out
How do I extend this. I have done research and found to try manually building the data source in the code but I have not successfully gotten that to work. But I also found to put a 'Connect Timeout' or 'Connection Timeout' or even just 'Timeout' in the connection string in the web.config file but no matter how large of a value I set after 30 seconds it times out. Here is what my connection string looks like:
<add name="xxxxx" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=xxxxx;initial catalog=xxxx;integrated security=True;Timeout=60000;Connect Timeout=60000;Connection Timeout=60000;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
Any help would be GREAT!
