Don’t worry, you’re not alone! Many developers have stumbled upon this frustrating issue when using Telerik.Reporting v18 with .Net ReportsController. But fear not, dear reader, for we’re about to embark on a journey to resolve this pesky problem once and for all!
What’s the Issue?
When using Telerik.Reporting v18 with .Net ReportsController, you might encounter an issue where the front end ReportViewer cannot resolve the reports. This can manifest in various ways, such as:
- Error messages like “Report cannot be resolved” or “Invalid report URI”
- ReportViewer displaying a blank page or a generic error message
- Reports failing to load or render properly
This issue often arises due to misconfiguration, incorrect setup, or version incompatibilities between Telerik.Reporting and .Net ReportsController. But don’t worry, we’ll tackle each possible cause and provide solutions to get your reports up and running in no time!
Prerequisites and Setup
Before diving into the solutions, make sure you have the following setup:
- Telerik.Reporting v18 installed and configured properly
- .Net ReportsController set up and running
- A front-end ReportViewer component integrated into your application
- A report definition (TRDP or TRDX) created and saved in the correct location
Double-check that you’ve met these prerequisites. If you’re unsure, revisit the Telerik.Reporting v18 and .Net ReportsController documentation for a refresher on the setup process.
Troubleshooting Steps
Let’s dive into the troubleshooting steps to resolve the issue:
Step 1: Verify Report Definition and Location
Ensure your report definition (TRDP or TRDX) is saved in the correct location and is correctly named. Check that the report definition is not corrupted or damaged during the deployment process.
<Reports>
<Report>
<ReportName>MyReport</ReportName>
<ReportResource>MyReport.trdx</ReportResource>
</Report>
</Reports>
In the above example, the report definition (MyReport.trdx) should be located in the same directory as the ReportsController.
Step 2: Check ReportsController Configuration
Verify that the ReportsController is properly configured to serve reports. Make sure the ReportsController is registered in the Web.config file:
<configuration>
<system.web>
<httpHandlers>
<add verb="*" path="Telerik.ReportViewer.axd" type="Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=18.1.20.1016, Culture=neutral, PublicKeyToken=a9d7983df204ce51"/>
</httpHandlers>
</system.web>
</configuration>
Also, ensure that the ReportViewer’s Report property is set to the correct report URI:
<telerik:ReportViewer ID="ReportViewer1" runat="server" Report="MyReport"> </telerik:ReportViewer>
Step 3: Inspect ReportViewer Configuration
Verify that the ReportViewer is properly configured to display reports. Check the ReportViewer’s settings, such as:
<telerik:ReportViewer ID="ReportViewer1" runat="server" Report="MyReport" ReportName="MyReport" EnableTheming="True" Theme=" Bootstrap"> </telerik:ReportViewer>
Make sure the ReportViewer’s Report property is set to the correct report URI, and the ReportName property matches the report definition name.
Step 4: Check Version Compatibility
Ensure that the Telerik.Reporting v18 and .Net ReportsController versions are compatible. You can check the version compatibility in the Telerik documentation or by contacting Telerik support.
Additional Tips and Tricks
Here are some additional tips to help you resolve the issue:
- Clear your browser cache and try again
- Use Fiddler or a similar tool to inspect the HTTP requests and responses
- Check the ReportViewer’s error messages for any clues
- Enable debugging and tracing in the ReportsController to gather more information
- Verify that the report definition is correct and has no syntax errors

Frequently Asked Questions
Stuck with Telerik.Reporting v18 and .Net ReportsController? Don’t worry, we’ve got you covered! Here are some frequently asked questions to help you resolve the issues with your front-end ReportViewer.
What is the most common reason for the ReportViewer to fail resolving reports in Telerik.Reporting v18?
The most common reason is that the ReportsController is not properly configured or registered in the application. Make sure you have registered the ReportsController in the Startup.cs file and configured it correctly.
How do I configure the ReportsController to work with the ReportViewer in Telerik.Reporting v18?
You need to configure the ReportsController by specifying the report sources, report resolver, and other settings. You can do this by creating an instance of the ReportsController and setting its properties, such as ReportSourceResolver, ReportResolver, and others, in the Startup.cs file.
What is the role of the ReportSourceResolver in the ReportsController configuration?
The ReportSourceResolver is responsible for resolving the report sources, such as .trdx or .trdp files, and providing them to the ReportViewer. You need to implement a custom ReportSourceResolver or use the built-in ones provided by TelerikReporting.
Why am I getting a “Report not found” error when trying to view a report in the ReportViewer?
This error usually occurs when the report source is not found or cannot be resolved by the ReportSourceResolver. Check that the report file exists and is correctly configured in the ReportsController, and that the ReportSourceResolver is correctly implemented and registered.
How do I troubleshoot issues with the ReportsController and ReportViewer in Telerik.Reporting v18?
To troubleshoot issues, check the application logs for errors, use debugging tools to inspect the ReportsController and ReportViewer instances, and verify that the report sources and resolvers are correctly configured. You can also use the TelerikReporting troubleshooting guide and community resources for further assistance.
