Problem with checkbox field in datagrid-groupview

[patana]

When combining datagrid-groupview with checkbox field,

Code:

$(this).datagrid('getChecked').length

do not show the correct number of checked box.
Please help!

Please refer to this example http://jsfiddle.net/dGmSu/. It can return the correct checked row count.

I found the problem. If i set idField:'id' to datagrid, then the number of checked row was incorrect.
Could I count the number of checked row base on grouped row?

Here is the updated example that set idField field. It also works well.

Suppose I want to count checked row base on productid field, how?

[stworthy]

You have set a wrong 'idField' value. The 'idField' value must be unique.

I see, But could i count checked row base on productid?
