## Parameter.Sources

### Introduced

v7.5

### Description

Returns all DataSource objects connected to this parameter in a DataSourceCollection. The collection is filled from the most significant source (the source driving the current parameter value) to the least significant. In the case where you do have a DataSource the first element of the collection returned by Parameter.Sources is the same as the element returned by Parameter.Source. For more information on sources, see Parameter.Source.

### C# Syntax

    // get accessor

    DataSourceCollection rtn = Parameter.Sources;

### Examples

#### Python Example

    #

    # This example shows how to access all sources on a parameter.

    #

    from win32com.client import constants

    xsi = Application

    myNull = xsi.ActiveSceneRoot.AddNull("myNull");

    posx = myNull.posx;

    posx.AddFCurve();

    xsi.AddAnimationLayer("Scene_Root","",1);

    xsi.SelectObj("myNull", "", True)

    xsi.Translate("", 0, 1.02887578257936, 0, "siRelative", "siGlobal", "siObj", "siXYZ", "", "", "", "", "", "", "", "", "", 0, "");

    Application.SaveKey("myNull.kine.local.posx", 1, "", "", "", False, "")

    sources = myNull.PosX.sources;

    for source in sources:

    	xsi.LogMessage( "Source: " + str(source.FullName) )

    # Expected results

    # INFO : Source: Mixer

    # INFO : Source: FCurve
