## UserDataMap.ItemValue

### Introduced

v3.0

### Description

Returns or sets the data on a particular component inside the user data map as a String.
The user data is represented as a string for the sake of scripting languages, but from C++ it is also possible to encode binary data.
This is equivalent to retrieving a UserDataItem with UserDataMap.Item and then using the UserDataItem.Value property.
Note: Since Python does not support input parameters on properties, this will fail in Python. Use the Python-compliant UserDataMap.GetItemValue2 method instead.
Warning: If your plug-in accesses UserDataMap data on multiple platforms (Windows vs. Linux), the contents of the ItemValue property might not translate exactly because the size of a character differs from one OS to the other.

### C# Syntax

    // get accessor

    String UserDataMap.get_ItemValue( Int32 in_ulIndex );

    // set accessor

    UserDataMap.set_ItemValue( Int32 in_ulIndex, String out_pbstrVal );

### Parameters

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