I was guessing this was a short NO answer, So I apologize for not providing enough information.
Yes, I know that VM's need to be accessed by set(), get(). So I am not having problems with the
value attribute, which I am updating that way.
1.
<
div
class
=
"Part Line"
>
2.
<
progress
3.
id
=
"ProgressBar"
4.
class
=
"Stretch"
5.
data-bind
=
"attr: { max: TotalFiles, value: TileCount }"
></
progress
>
6.
<
span
class
=
"Fixed"
>100%</
span
>
7.
</
div

However, the max attribute is coming from a calculated function in the VM which is getting it's value from the aggregate sum of a DataSource bound to a Grid.
