ActionInvocation Enumeration

Defines how an Action is called.

Namespace:  Microsoft.AnalysisServices
Assembly:  Microsoft.AnalysisServices (in Microsoft.AnalysisServices.dll)

[GuidAttribute("B3C87F4E-DC00-449d-AADB-57A239DC0B1C")]
public enum ActionInvocation

Member nameDescription
BatchCalls the action from a batch command.
InteractiveCalls the action when a user performs an action.
OnOpenCalls the action when the cube opens.

New:   17 July 2006

Only Interactive has been implemented in SQL Server 2005 Analysis Services (SSAS).

Batch and OnOpen members will be implemented in future releases of SQL Server Analysis Services.

Using unimplemented members of ActionInvocation creates an empty table from the MDSCHEMA_ACTIONS Rowset.

This section includes two samples; one sample using AMO to set up the action and another sample using ADOMD.NET client to retrieve the action from client code.

The following sample, which uses AMO, shows how to set up an action. The sample assumes that you are connected to AMOAdventureWorks sample database and the cube passed as parameter is "Adventure Works".

Notice that action invocation is defined as Interactive in the code.

The code is written in C#.

    //Define the Action
    action.Invocation = ActionInvocation.Interactive;
    action.Type = ActionType.DrillThrough;
    action.TargetType = ActionTargetType.Cells;
    action.Target = "MeasureGroupMeasures(\"Reseller Sales\")";
    action.Caption = "DrillThrough...";
    action.CaptionIsMdx = false;

    //Adding Measure columns
    MeasureBinding mb1 = new MeasureBinding();
    mb1.MeasureID = "Reseller Sales Amount";
    action.Columns.Add(mb1);

    MeasureBinding mb2 = new MeasureBinding();
    mb2.MeasureID = "Reseller Order Quantity";
    action.Columns.Add(mb2);

    MeasureBinding mb3 = new MeasureBinding();
    mb3.MeasureID = "Reseller Unit Price";
    action.Columns.Add(mb3);

    //Adding Dimension Columns
    CubeAttributeBinding cb1 = new CubeAttributeBinding();
    cb1.CubeID = "Amo Adventure Works";
    cb1.CubeDimensionID = "Reseller";
    cb1.AttributeID = "Reseller";
    cb1.Type = AttributeBindingType.All;
    action.Columns.Add(cb1);

    CubeAttributeBinding cb2 = new CubeAttributeBinding();
    cb2.CubeID = "Amo Adventure Works";
    cb2.CubeDimensionID = "Product";
    cb2.AttributeID = "Product Name";
    cb2.Type = AttributeBindingType.All;
    action.Columns.Add(cb2);

    //Add the defined action to the cube
    cube.Actions.Add(action);
    #endregion
}

The following sample, which uses the ADOMD.NET client, shows how to verify that the action sample is defined correctly.

The parameters were given as follows.

CATALOG_NAME= AmoAdventureWorks

CUBE_NAME=Adventure Works

COORDINATE=([Measures].[Reseller Order Quantity], [Product].[Category].&[3])

COORDINATE_TYPE=6

Code is written in C#. ServerName is a System.Windows.Forms.Textbox object on a Form.

    restrictions.Add("COORDINATE", coordinate);

    restrictions.Add("COORDINATE_TYPE", (int)coordinateType);
    foreach (adoMdClient.AdomdRestriction restriction in restrictions)
    {
Debug.WriteLine(restriction.Name + "=" + restriction.Value);
    }
    using (adoMdClient.AdomdConnection cnxAmoAdventureworks = new adoMdClient.AdomdConnection())
    {
if (serverName.Text.Length == 0)
{
    cnxAmoAdventureworks.ConnectionString = "Data Source=localhost;Catalog=AMOAdventureworks";
}
else
{
    cnxAmoAdventureworks.ConnectionString = "Data Source=" + serverName.Text + ";Catalog=AMOAdventureworks";
}
cnxAmoAdventureworks.Open();


DataTable actionsTable = cnxAmoAdventureworks.GetSchemaDataSet("MDSCHEMA_ACTIONS", restrictions).Tables[0];
Debug.WriteLine("Table [" + actionsTable.TableName + "] has " + actionsTable.Rows.Count.ToString() + " rows");
int j = 0;
foreach (DataRow actionRow in actionsTable.Rows)
{
    for (int i = 0; i < actionRow.ItemArray.Length; i++)
    {
Debug.WriteLine("[" + j.ToString().PadLeft(4) + "]\t" + actionsTable.Columns[i].ColumnName + ": " + actionRow.ItemArray[i].ToString());
    }
    j++;
}
    }

}

After running the code you will see the following results.
