How to "clear" a DataSource used in MVVM

Hi,

What is the recommended way to "clear" a DataSource used in an MVVM scenario ?

For example, if I bind a ListView to a DataSource wrapped inside an ObservableObject, what is the recommended way to clear all the items ?

Thanks

DROID support pre v3 and DataViz Graphics

Currently I am evaluating the kendo MOBILE library in conjuction with the DataViz library and I find the work great btw! My issues mainly come from testing on my internal DROID devices.

Spoofing DROID through web browsers is find but actually testing on a DROID device pre v3 of the Android OS becomes problematic as it does not seem to support SVG or VGL.

I noticed that on the web site decribing DataViz that Android is supported: Android (via Opera and the Android browser v3+)

Are you saying that a best practice work around for older droid devices (can ice cream sandwich come quick enough?) that we should use Opera Mobi? or maybe Opera Mini?

Forcing operations to commit

Okay, I am in a situation where I need every new entry in my grid to validate against all existing entries to determine whether or not it can be added. The problem is, saving with the grid always sends all adds and removes at once and in parallel, so their execution order is undefined. So it is possible for new entries to fail validation against old entries that are in the process of being removed.

My natural conclusion is that I need to just force an update after every operation (add, remove, etc). The problem is, that when I try to use the "save" and "remove" events, "this.saveChanges()" doesn't do anything. Is there a more correct way to obtain this behavior?

Thanks.

Event fired when Expand is complete?

It seems that I can bind to the 'expand' event to capture when the panel is about to expand. Is there any event fire when the expansion is complete?

Can you perform math inside a template?

// Disregard, I figured it out...//

I have a template that is being loaded via a JSON file. My JSON file contains data I would like to use to set CSS parameters in the rendered html.

Is it possible to have a function inside the template that performs a calculation on the JSON data and them uses the result to modify a CSS parameter?
