Tricksy Parameter Prompts

Q: How to make the darn parameter drop-down list wider in HTMLViewer? HTMLViewer is the Report Manager control that displays the report when you view the report.

A: HTMLViewer supports limited customization via a CSS stylesheet.

1. Copy HTMLViewer.css to MyHTMLViewer.css in the same folder (Reporting Services\ReportServer\Styles). Note that the actual folder path varies between SQL Server versions.
2. Add the following CSS style to MyHTMLViewer.css

SELECT {

font-size: 8pt;

font-family: Verdana;

width:200px

}

As a result, all SELECT elements on the page (all dropdowns, such as parameter prompts, zoom, export) will pick up these settings.

1. Configure the server to use the custom stylesheet by one of these options:
   1. If you want to apply the custom styles to all reports, add a new HTMLViewerStyleSheet element to the rsreportserver.config file, such as:

<Configuration>

…

<HTMLViewerStyleSheet>MyStyleSheet</HTMLViewerStyleSheet>

…

</Configuration>

Note that due to an unfortunate bug, the HTMLViewerStyleSheet setting doesn’t work with February CTP of SQL Server 2008 but it will be fixed in the final release.

1. Use the rs:Stylesheet device setting to apply the custom style to given report only, such as:

http://localhost/ReportServer?/AdventureWorks Sample Reports/Product Line Sales&rs:Command=Render&rc:Stylesheet=MyStylesheet
