## 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
