## UserDataMap.GetItemSize2

### Introduced

v6.0

### Description

Returns the size (in bytes) of the data attached to a particular component of the user data map.
This is equivalent to retrieving a UserDataItem with UserDataMap.GetItem2 and then using the UserDataItem.Size property.
Note: This is the Python-compliant version of the UserDataMap.ItemSize. Since Python does not support input parameters on properties, UserDataMap.ItemSize will fail in Python.

### C# Syntax

    Int32 UserDataMap.GetItemSize2( Int32 in_ulIndex );

### Scripting Syntax

    oLong = UserDataMap.GetItemSize2( Index );

### Return Value

Long

### Parameters

Parameter | Type | Description
--- | --- | ---
Index | Long | Index of the component within the cluster.
