Before you print or preview a report, the client checks the page width and page height to verify that the paper size is supported by the printer. After you create an RDLC report layout, to ensure that you can print and preview the report, you must verify that the page width and page height properties are valid.
To verify the page height and page width properties
In the development environment, on the Tools menu, choose Object Designer.
In Object Designer, choose Report, select a report that you want to modify, and then choose the Design button.
On the View menu, choose Layout.
In Microsoft Visual Studio, in the Report.rdlc file, on the Report menu, choose Report Properties.
In the Report Properties window, on the Layout tab, verify that the values in the Page width and Page height fields are valid.
The following table shows valid paper size dimensions.
