CRMProcess.RetrieveActionParameter Method

The RetrieveActionParameter method retrieves the specified parameter for an action.

Syntax

[Visual Basic .NET]
Public Function RetrieveActionParameter(
  ByVal Caller As CUserAuth,
  ByVal ParameterId As String,
  ByVal ColumnSetXML As String
) As String
[C#]
public string RetrieveActionParameter(
  CUserAuth  Caller,
  string  ParameterId,
  string  ColumnSetXML
);
[C++]
public: String* RetrieveActionParameter(
  CUserAuth*  Caller,
  String*  ParameterId,
  String*  ColumnSetXML
);

Parameters

Caller

Specifies the identity of the caller. To perform this action, the caller must have the prvReadWorkflowProcess privilege and access rights on the object to be retrieved. See CUserAuth.

ParameterId

Specifies the ID of the parameter to be retrieved.

ColumnSetXML

Specifies an XML string describing the set of columns to be retrieved. Passing an empty string or null returns all columns (Nothing or "" in VB .NET). You can find the valid column names in wfparameter.xsd. See also ColumnSetXML Schema.

Return Value

Returns a String type that specifies the XML data containing the parameter. The fields that are returned depend on what fields are specified in the ColumnSetXML parameter. The XML schema is described by wfparameter.xsd.

Remarks

This method always returns a single object so any filter criteria specified in the ColumnSetXML parameter are ignored.

The XML string returned from this method does not contain elements for fields where the value is null or contains empty strings. This improves performance by not sending more XML data than is necessary from the server to the client.

If there is an error, SOAP throws an exception and the error message is reported in System.Web.Services.Protocols.SoapException.Detail.OuterXml.

All IDs passed to the platform are GUIDs wrapped in braces. For example: {6522D89A-A752-4455-A2B0-51494C6957C3}

Example

[C#]
// strServer should be set with the name of the platform Web server
string strServer = "myservername";

// virtualDirectory should be set with the name of the Microsoft CRM
// virtual directory on the platform Web server
string virtualDirectory = "mscrmservices";
string strDir = "https://" + strServer + "/" + virtualDirectory + "/";

// BizUser proxy object
Microsoft.Crm.Platform.Proxy.BizUser bizUser = new Microsoft.Crm.Platform.Proxy.BizUser ();
bizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
bizUser.Url = strDir + "BizUser.srf";

// CRMProcess proxy object
Microsoft.Crm.Platform.Proxy.CRMProcess  process = new Microsoft.Crm.Platform.Proxy.CRMProcess();
process.Credentials = System.Net.CredentialCache.DefaultCredentials;
process.Url = strDir + "CRMProcess.srf";

string strErrorMsg;
try
{
   Microsoft.Crm.Platform.Proxy.CUserAuth userAuth = bizUser.WhoAmI();

   string strParamId = "{D9A55D5B-390B-4DAC-87C8-F38AD2169F38}";

   // Set up the columns that you want to retrieve
   string strColumnSetXml = "<columnset>";
   strColumnSetXml += "<column>parameterid</column>";
   strColumnSetXml += "<column>parentid</column>";
   strColumnSetXml += "<column>conditionid</column>";
   strColumnSetXml += "<column>value</column>";
   strColumnSetXml += "</columnset>";

   // Retrieve the action parameter
   string strParamXml = process.RetrieveActionParameter(userAuth, strParamId, strColumnSetXml);
}
catch (System.Web.Services.Protocols.SoapException err)
{
   // Process the platform error here
   strErrorMsg = ("ErrorMessage: " + err.Message + " " + err.Detail.OuterXml + " Source: " + err.Source );
}
catch (Exception err)
{
   // Process other errors here
   strErrorMsg = ("ErrorMessage: " + err.Message );
}
