Proper way to defer binding

[jmillar]

Hi all;

I have a mobile list view bound to a server filtered datasource.  The filter, though, is going to be based on an attribute of the Users.currentUser() return.  For example, the list is bound to a set of customer quality names filtered by the customer ID for the currently logged in user.  I have it working by changing the filter on the data-show event of my view and doing a .read() on the data source, but that causes an extra round trip since the list is initially bound to an empty view.

What I'm taking a long time to ask is....can anybody share the "proper" way to dynamically change the filters for a data source based on the current state of something in the UI?  I realize I haven't posted an example, but hopefully my description of what I'm trying to accomplish is relatively straightfoward.

Thanks,
Jason

Hi Jmillar,

You may set the autoBind configuration option of the ListView to false to suppress the initial dataSource read. In that way the DataSource will send request to the server only when the filters are set through the filter method. There is no need to call .read() after .filter().
