Hello,

Thank you for the screenshot!

Please visit the Resize the default Document Map and Parameter areas sizes through the splitter - Telerik Reporting KB article for details on how to resize the parameters/document map area of the HTML5-based Report Viewers.

Can you guide me through to the process? as I'm focusing more on report designer. I'm making reports on report designer and publish it right after I'm done and  check it directly to local report server.

If I understand correctly, you are using the Web Report Designer of a Telerik Report Server instance, is that correct?

In that case, the code from the Resize the default Document Map and Parameter areas sizes through the splitter - Telerik Reporting KB article must be applied to the view in which the HTML5 Report Viewer is rendered. You may find the .CSHTML for the report preview at the following path(assuming default install directory):

C:\Program Files (x86)\Progress\Telerik Report Server\Telerik.ReportServer.Web\Views\Report\Preview.cshtml

For more details on how to customize the report preview in Telerik Report Server, you may refer to the How to customize preview in Report Server - Telerik Report Server KB article.
