Issues on connecting Telerik Reporting Standalone Report Designer to Telerik Report Server.

Warning message on connecting Telerik Reporting Standalone Report Designer to Telerik Report Server:

Error message on web preview of a published/uploaded report through Telerik Report Server:


DESCRIPTION
Telerik Report Server uses the same Standalone Report Designer as the one provided by Telerik Reporting. The designer can be downloaded via ClickOnce in Internet Explorer, or by using the download link provided in Chrome, Firefox and other browsers lacking ClickOnce support, by users having access to the Admin module of the Report Server (CALs).

If you already have Telerik Reporting, you can use the designer's located in [Install_Folder]\Report Designer, where you need to provide your user's credentials to connect to the Report Server.

SOLUTION
Telerik Reports are Telerik.Reporting.Report objects which can be serialized in XML(TRDX files), or compressed XML(TRDP files). The XML definition has a schema version that is updated in case of API changes in the released reporting functionality.
It is important to use the same version of Telerik Reporting Standalone Report Designer as the one of Telerik Report Server, which guarantees you are using the same version of Telerik Reporting engine to create and process reports. For example, Telerik Reporting 10.2.16.1025 is compatible with Telerik Report Server 2.2.16.1025.

In addition:

1. Telerik Reporting Standalone Report Designer can be connected to Telerik Report Server, if they are of the same version. Then the user can log in, and reports can be created, edited and published through the designer;
2. You can manually upload and preview reports (TRDX|TRDP files) created with an older version of Telerik Reporting Standalone Report Designer through the Admin Module of Telerik Report Server;
3. Reports generated by newer versions of Telerik Reporting Standalone Report Designer may not be processed and displayed by Telerik Report Server. In case of XML schema update in Telerik Reporting engine, you will receive an error message pointing the schema version of the report's XML and that you are using an older version of the reporting engine to process that XML.
4. Older versions of Telerik Reporting Standalone Report Designer may let you connect them to a newer version of Telerik Report Server, but the designer may malfunction and not let you accomplish your task.

Note: If you are in doubt which report designer to use, our recommendation is to use the Standalone Report Designer distributed by Telerik Report Server via ClickOnce in IE browser or download link in other browsers.
