RDLC - ReportViewer Control

Question

RDLC - ReportViewer Control

Kartmen 20

Is there any documentation on how RDLC calculates text sizes? In the designer it's a control and thus is rendered using the graphic class. But in the preview the text looks different. Is there any way to know what dimensions the text will have in the preview?

Hi,@Kartmen. Welcome to Microsoft Q&A Forum.

RDLC uses GDI+ (Graphics Device Interface) for rendering, and the text rendering in RDLC reports can sometimes vary from what you see in the report designer. This discrepancy can occur due to differences in rendering engines, font rendering, and rendering options.

RDLC reports are designed to be relatively simple, and while there is documentation on how to use RDLC reports, it doesn't go into great detail on the inner workings of text rendering。

Text Rendering Engine: The RDLC rendering engine may not have the same advanced text rendering capabilities as a full desktop publishing or design application. Therefore, small discrepancies in text rendering are not uncommon.

If you need precise control over text rendering, consider using a more advanced reporting tool or library that provides greater control over the rendering engine. Tools like SQL Server Reporting Services (SSRS) or third-party reporting libraries often offer more extensive options for customizing text rendering.

While RDLC is suitable for many basic reporting needs, it may not be ideal for complex formatting or precise control over text rendering, especially when fine-tuning is required.

One more question... how hard is it to switch to SSRS when the project is targeting to Net.Framework 4.5.1?

Hi,@Kartmen. Switching to SQL Server Reporting Services (SSRS) from a project targeting .NET Framework 4.5.1 might involve some adjustments.

Here are some key considerations and steps for making the transition:

Compatibility Check: Ensure that the version of SSRS you plan to use is compatible with the .NET Framework 4.5.1.

Installation and Configuration: Install and configure SSRS on your server or environment, and set up data sources, report server URLs, and security settings as needed.

Reporting Services Project: Create a new SSRS project within SQL Server Data Tools (SSDT) for Visual Studio. This will allow you to set up and configure your SSRS reports, datasets, and data sources.

Report Migration: Migrate your existing reports from your current reporting solution to SSRS. You may need to recreate the reports, datasets, and any custom report functionalities within the SSRS project.

Integration with .NET Application: Update your .NET application to integrate with SSRS. This may involve modifying any report viewer controls and adjusting any report-related functionalities in your application.

Testing and Validation: Thoroughly test the integrated solution to ensure that the reports render correctly and that the application interacts properly with the SSRS reports.

Deployment: Deploy the updated application, along with the integrated SSRS reports, to your production environment once all testing and validation are complete.
