UIX - getting property values from selected item

The ObjectVersionAndProperties instance also has a property named "Properties" which is effectively a collection you can use to retrieve the object's metadata.  You would need to use the appropriate methods on that to retrieve the information you need.

Ok so if I use ObjectVersionAndProperties how would get the string from a specific property. would I use the ID of the property or the alias?

How would you do it without ObjectVersionAndProperties?

var objectVersionAndProperties = selectedItems.ObjectVersionAndProperties[0];
var objectVersion = objectVersionAndProperties.VersionData;
var properties = objectVersionAndProperties.Properties;

// Now work with the available information that the properties class exposes,
// ref: https://developer.m-files.com/APIs/COM-API/Reference/#MFilesAPI~PropertyValues.html

var nameOrTitlePropertyValue = getPropertyValueById(properties, 0);
if(null != nameOrTitlePropertyValue)
{
  shellFrame.ShowMessage("Object is named: " + nameOrTitlePropertyValue.GetValueAsLocalizedText());
}

var classPropertyValue = getPropertyValueById(properties, 100);
if(null != classPropertyValue)
{
  shellFrame.ShowMessage("Object is in class: " + classPropertyValue.GetValueAsLocalizedText());
}

// Some helpers.
function getPropertyValueById(pv, id)
{
  var index = pv.IndexOf(id);
  if(index == -1)
    return null;
  return pv[index];
}
function getPropertyValueByAlias(pv, alias)
{
  var index = pv.IndexOfByAlias(id);
  if(index == -1)
    return null;
  return pv[index];
}

Thankyou so much. We have gotten the results we were looking for
