Public Function GetItemParameters (ItemPath As String, HistoryID As String, ForRendering As Boolean, Values As ParameterValue(), Credentials As DataSourceCredentials()) As ItemParameter()

Parameters

ItemPath: String

The fully qualified URL of the item including the file name and, in SharePoint mode, the extension.

HistoryID: 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 null (Nothing in Visual Basic) if you are retrieving parameters for an item that is not an item history snapshot.

ForRendering: 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.

Values: ParameterValue[]

The parameter values (ParameterValue objects) that can be validated against the parameters of an item that is managed by the report server.

Credentials: DataSourceCredentials[]

The data source credentials (DataSourceCredentials objects) that can be used to validate query parameters.

Returns

ItemParameter[]

An array of ItemParameter objects that lists the parameters for the item.

Attributes: SoapDocumentMethodAttribute SoapHeaderAttribute

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:

Imports System  
Imports System.Web.Services.Protocols  

Class Sample  
   Public Shared Sub Main()  
      Dim rs As New ReportingService2010()  
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials  

      Dim report As String = "/SampleReports/Employee Sales Summary"  
      Dim forRendering As Boolean = False  
      Dim historyID As String = Nothing  
      Dim values As ParameterValue() = Nothing  
      Dim credentials As DataSourceCredentials() = Nothing  
      Dim parameters As ItemParameter() = Nothing  

      Try  
         parameters = rs.GetItemParameters(report, historyID, forRendering, values, credentials)  

         If Not (parameters Is Nothing) Then  
            Dim rp As ItemParameter  
            For Each rp In parameters  
               Console.WriteLine("Name: {0}", rp.Name)  
            Next rp  
         End If  

      Catch e As SoapException  
         Console.WriteLine(e.Detail.InnerXml.ToString())  
      End Try  
   End Sub 'Main  
End Class 'Sample

using System;

   public static void Main()  
   {  
      ReportingService2010 rs = new ReportingService2010();  
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials;  

      string report = "/SampleReports/Employee Sales Summary";  
      bool forRendering = false;  
      string historyID = null;  
      ParameterValue[] values = null;  
      DataSourceCredentials[] credentials = null;  
      ItemParameter[] parameters = null;  

      try  
      {  
         parameters = rs.GetItemParameters(report, historyID, forRendering, values, credentials);  

         if (parameters != null)  
         {  
            foreach (ItemParameter rp in parameters)  
            {  
               Console.WriteLine("Name: {0}", rp.Name);  
            }  
         }  
      }  

      catch (SoapException e)  
      {  
         Console.WriteLine(e.Detail.InnerXml.ToString());   
      }  
   }  
}

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 totrue, 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.
