Hello Juan Sebastián,
Generally, the Telerik Reporting version referred in the project with the reports and with the viewers displaying them need to match. You can use our Upgrade Wizard
to upgrade/downgrade to the required version available on the machine.
The exception from the screenshot indicates that the referred Telerik Reporting version in the project is 22.214.171.1248
, and it cannot be found. You can either install this version if not available, or upgrade/downgrade the project to an available version.
In some cases when there are more that one versions of Telerik Reporting installed on the same machine a conflict may occur, as the assemblies get deployed in the GAC. You can check which is the exact version loaded by Visual Studio to be used by the project in the list of loaded assemblies : How do I list all loaded assemblies?
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
