DataTemplateSelector in SfListView

[Jason]

Is it possible to have a data templateselector in the Listview, I want to be able to bind to several different data templates based from a value on the bound items, is this possible with SfListView?

Regards

Jason

Another response that is (well I have to be somewhat rude) screwed.  There is no  DataTemplateSelector property in the SfListView so everything in this post is wr

[Lakshmi Natarajan]

Hi Lloyd, 

 

The SfListView allows customizing appearance of each item with different templates based on specific constraints by using the DataTemplateSelector. 

 

We have user guidance document for the same and you can refer from the following link,
