SmartGWT DataSource with HTTP URL

[subramanyam_ln]

1. I am using Smart GWT latest version 2.4.
I have a ListGrid which gets the data from the DataSource. The datasource is pointing to a HTTP servlet URL.
dataSource.setDataURL(http://servlet/TestServlet).
I am setting a http request parameter(status=Active) as below
DSRequest request = new DSRequest();
request.setParams(criteriaMap); // has key = status; value = Active
dataSource.setRequestProperties(request);
Now ListGrid.fetchData() will fetch all the records where status is Active

2. I have 2 buttons called Pending and Failed, on click of Pending, I have to pass status as Pending and fetch all the records with Pending, same with the case of Failed button click also.

I want to achieve this with the same ListGrid, the grid should refresh and display correcponding records on click of respective buttons.

Can anyone please suggest the way I can achieve?

Thanks in advance

Why you trying to use request parameters for passing fetch criteria ?
You can use ListGrid.fetchData(Criteria criteria)
