Customizing the Report Viewer Web Part

New: 12 December 2006

You can use the Report Viewer Web Part to view reports that run on a SQL Server 2005 Reporting Services report server. Reports that you can display include report definition (.rdl) files and Report Builder reports. Reports open in the Report Viewer Web Part in a new page automatically, but you can also add a Report Viewer Web Part to an existing Web page or site if you want a particular report to always be visible on that page.

You can customize the Report Viewer Web Part in the following ways:

  • Change the appearance of the Web Part by setting properties.
  • Choose which interactive reporting features are available on the report toolbar.
  • Specify which view areas are available. The Report Viewer Web Part has a report view area, a Parameters area, and a Credentials area.

You cannot extend the Report Viewer Web Part to support different file types, and you cannot replace the report toolbar with a custom toolbar or add new functionality to the existing toolbar. If you require customization of the standard features, you should create a custom Web Part.

Setting Web Part Properties

A Web Part has custom properties that are used to configure specific functionality. A Web Part also has common properties that are standard for every Web Part.

Change Default Properties

The Report Viewer Web Part has default properties that are ideally suited for opening reports on demand from a library or folder. By default, all available controls are displayed on the toolbar, and height and width are set to use all the available space on the Web page. If you want to modify the default properties, you can customize the Web Part through Site Settings.

  1. On the Site Actions menu, click Site Settings.
  2. Under Galleries, click Web parts.
  3. Click ReportViewer.dwp.
  4. Open the tool pane and set the properties you want to use.

Customize an Embedded Report Viewer in a Web Page

You can set properties to make the Report Viewer fit within a Web page. The report viewer can use the same style and colors as the page that contains it. You can hide all or part of the toolbar, document map, and parameters area to maximize the report viewing area within the allocated space. The report always uses the styles that are defined for it when it was created; you cannot customize report appearance after it is published to a SharePoint library.

If you are embedding the Report Viewer Web Part in a Web page, you should set the Report URL property to a specific report. If you do not, the Report Viewer will display instructions for linking to a report. You cannot customize or remove the instructions.

Custom Properties of the Report Viewer Web Part

When setting custom properties, be aware that some properties are used only when the Report Viewer Web Part is embedded in a page. Examples include Title, Height, Width, Chrome type, and Zone. Other properties, such as Toolbar settings and Parameters settings, are used regardless of whether the Report Viewer appears within a page or opens a report in full-page mode.

The custom properties of the Report Viewer Web Part are listed below.

Property Description


A URL this is a fully qualified path to a report that is on the current SharePoint site, or on a site within the same Web application or farm. For best results when setting additional properties, click Apply after you specify the report URL.

Hyperlink Target

Hyperlink Target is standard HTML that specifies the target frame for displaying linked content within the current document. For drillthrough reports and for reports that include hyperlinks to external Web sites, you can specify whether a target document replaces the existing report within the current window, or opens in a new browser window. Valid values include _Top, _Blank, and _Self. _Top uses the current window, _Blank loads the document in a new browser window, and _Self opens the document within the current frame. Although _Parent is a valid value for the Target attribute in HTML, do not use it for a Report Viewer Web Part that is embedded in a page.

Auto-Generate Web Part Title

A generated title includes the name of the Report Viewer Web Part plus the name of the report, separated by a dash. If the report does not have a title, the report file name is used. The title is visible when you add a Web Part to a page. If this check box is selected, the title will be generated each time the page is refreshed.

Auto-Generate Web Part Title Detail Link

A generated hyperlink that appears above the Web Part. You can click the link to open the report in a new page, in full-page mode.


Valid values include Full, None, and Navigation. Full shows the entire toolbar. None hides the toolbar. Navigation shows just page navigation controls, without zoom, refresh, or the Actions menu.


Valid values include Displayed, Collapsed, and Hidden. Displayed displays the Parameters area for reports that include parameterized values and that require user input before the report will run. Use Hidden if all of the report parameters are specified and you do not want the parameters area to be visible to users.

Parameters Area Width

You can choose the measurement and value. The default is 200 pixels. The only requirement for this property is that it is greater than zero.

Document Map

A document map is a report navigation control that is defined in the report and used to provide one-click access to specific sections of a report. It is available in HTML reports. The document map is displayed in a collapsible area next to the report viewing area. Valid values include Displayed, Collapsed, and Hidden. If a document map is defined for a report, the area is expanded by default unless marked as hidden or collapsed in the Web Part properties. If the document map is collapsed, you can click the arrow to expand it.

Document Map Area Width

You can choose the measurement and value. The default is 200 pixels. The only requirement for this property is that it is greater than zero.

Load Parameters

Click this button to retrieve parameter properties for the report. Not all reports have parameters. If the report does not have parameters, no values will be returned. If you are setting properties for a report that you just uploaded, you might get an error indicating that the data source connection has been deleted. If this occurs, reset the connection and then finish setting parameter properties after the connection is specified. For instructions on how to set the connection, see How to: Create and Manage Shared Data Sources (SharePoint Integrated Mode).

For best results, click Apply before clicking Load Parameters.

After you load parameter properties, you can set them the same way you would in the parameter property pages of the report. For more information about how to set parameters, see How to: Set Parameters on a Published Report (SharePoint Integrated Mode).

Customizing the Toolbar

The toolbar appears underneath the title and extends across the top of the report. The toolbar provides an Actions menu, page navigation for paginated reports, refresh, and zoom. It includes a document map control for reports that have a document map. The Actions menu includes commands for exporting the report, searching for text or numbers within a report, printing the report, and, for model-based reports, opening the report in Report Builder.

You cannot customize the Actions menu or add new commands to it, but you can hide it by setting properties on the toolbar. You can also remove the Print command or specific export formats by making these features unavailable on the report server. Page navigation controls are available for reports that have page breaks; otherwise, the report is a single page of variable length. Refresh re-processes the report using the parameters that are current for the report. To display all the controls on one line, set the overall width of the Web Part to at least 400 pixels.

Customizing the Viewing Area

The view area is used to display reports. The report view area is shared with the Parameters and Credentials area, if they are used. If credentials are required, the Credentials area is displayed next to an empty report view area. The Credentials area closes after the user provides credentials and runs the report. To customize the text that prompts users to set credentials, modify the data source connection properties. For more information, see How to: Create and Manage Shared Data Sources (SharePoint Integrated Mode).

The Parameters area provides fields for entering values before running the report. It is only used when a report definition includes parameters. When either the Parameters or Credentials areas are displayed, the report view is adjusted to use the remaining width of the Web Part. You can set properties on the Web Part to customize the width of Parameters. You can also define the labels that appear next to individual parameters on the page. For more information about how to modify parameter labels, see How to: Set Parameters on a Published Report (SharePoint Integrated Mode).
