<div style="font-size:12px;">
This example demonstrates using a subgrid with JSON Data. To the subgrid url is passed the id of the row.<br/>
If there is a need to pass another parameters to subgrid url that are part of the grid data a params array <br>
can be constructed. Example: if we want to pass the date too - the subGridModel can look like this: <br>
... <br>
subGridModel: [{ name  : ['No','Item','Qty','Unit','Line Total'], <br>
width : [55,200,80,80,80], <br>
params: ['invdate']} <br>
... <br>
where the 'invdate' is a valid name from colModel. And a parameter invdate='xxxxx' is constructed<br>
