Well, the title says it all!  
I have the `templateParams` bound to a named query, and would like to resize the repeater based on the number of templates.

Thanks!

You could trigger a transform call to resize or reposition the repeater using the `templateParams` propertyChange event. The code would look something like this:

```python
if event.propertyName == 'templateParams':
	
	# Set the height of the repeater to 50 pixels per template
	newHeight = 50 * event.newValue.rowCount
	system.gui.transform(event.source, newHeight = newHeight)

```

See the user manual for additional options:

Thank you, Justin. That's exactly what I needed.
