Sample: Use QueryExpression with a paging cookie
This sample shows how to use the paging cookie in a QueryExpression query to retrieve successive pages of query results. It uses the IOrganizationService.RetrieveMultiple method.
How to run this sample
- Download or clone the Samples repo so that you have a local copy.
- (Optional) Edit the dataverse/App.config file to define a connection string specifying the Microsoft Dataverse instance you want to connect to.
- Open the sample solution in Visual Studio and press F5 to run the sample. After you specify a connection string in dataverse/App.config, any sample you run will use that connection information.
If you do not specify a connection string in dataverse/App.config file, a dialog will open each time you run the sample and you will need to enter information about which Dataverse instance you want to connect to and which credentials you want to use. This dialog will cache previous connections so that you can choose a previously used connection.
Those samples in this repo that require a connection to a Dataverse instance to run will include a linked reference to the dataverse/App.config file.
What this sample does
The IOrganizationService.RetreiveMultiple
method is intended to be used in a scenario where it retrieves a collection of records.
How this sample works

Setup
- Checks for the current version of the org.
- The
Account
method creates a parent account record and 10 child account records.
Demonstrate
- The
ConditionExpress
defines the condition expression for retrieving records. - The
OrderExpression
method defines the order expression to retrieve the records.
Clean up
Displays an option to delete all the data created in the sample. The deletion is optional in case you want to examine the data created by the sample. You can manually delete the data to achieve same results.
