Parameters

  • ItemPath
    Type: System.String
    The fully qualified URL of the item including the file name and, in SharePoint mode, the extension.
  • HistoryID
    Type: System.String
    The ID of the item history snapshot. Set the ForRendering parameter to a value of true in order to retrieve parameter properties for an item history snapshot. Set the value to nulla null reference (Nothing in Visual Basic) (Nothing in Visual Basic) if you are retrieving parameters for an item that is not an item history snapshot.
  • ForRendering
    Type: System.Boolean
    A Boolean expression that indicates how the parameter values are to be used. If set to a value of true, parameter properties that are returned are based on the parameter data that was used during the execution of the item.

Return Value

Type: array<ReportService2010.ItemParameter[]
An array of ItemParameter objects that lists the parameters for the item.

ViewListItems

If the execution setting for the item is Snapshot, the parameter metadata that is returned is the data that was used when the item history snapshot was created. If the execution setting for the item is Live, the parameter metadata returned represents the parameter data that is associated with the specified item.

If you provide a value for the HistoryID parameter and set the ForRendering parameter value to true, the parameter metadata returned represents the parameter data that was used when the item history snapshot was created. The value supplied for HistoryID is ignored if ForRendering is set to false.If ForRendering is false, the parameter metadata returned represents the parameter data that is currently associated with the specified item.

If any parameters values are based on a query and you are interested in returning the query-based parameters' valid values list, set ForRendering to true. In addition, for query-based parameters, you must pass in all of the credential information required to return the query parameters.

When using the GetItemParameters method to validate parameters, the Values parameter is required.

If parameters do not exist for the given item, an empty ItemParameter array is returned.

Examples

To compile this code example, you must reference the Reporting Services WSDL and import certain namespaces. For more information, see Compiling and Running Code Examples. The following code example uses the GetItemParameters method to retrieve a list of parameter metadata for a report and then displays the name of each parameter:
