When viewing a deployed, SQL Server Reporting Services (SSRS) report, the default pagination does not provide a pleasant user experience because viewing more than a handful of rows of report data requires that the user page right and page left.
To display all rows of data on the first page of the SSRS report, set InteractiveSize properties (Width and Height) to 0.
After updating the properties, Save the report, then Deploy the report.
Refresh the report in the browser and now all of the report data will display on the page. If viewing the report in SharePoint using a Report Viewer Web Part, then you may need to adjust the Height and Width of the Report Viewer Web Part to eliminate any scroll bars that appear as a result of the data being displayed on one page.
