TreeGrid filtering on client

[mpretorian]

Hi,

I would like to achieve to load from server a datasource bound tree grid with rows (parent/child relation) based on a simple criteria composed of 3 field/values and then allow the user to filter the rows on client based on other fields. Is is possible?

I tried the following setup but it didn't work. Here is the code:

public class CustomTreeGrid extends TreeGrid {
public CustomTreeGrid() {

	setDataSource(dataSource);
	setAutoFetchData(false);
	setShowFilterEditor(true);
	setLoadDataOnDemand(false);

	setKeepParentsOnFilter(true);
	setServerFilterFields("f1","f2","f3");        

	setFields(f1,f2,f3,f4,f5,f6);//f1-6 are TreeGridField objects
}

public void fetchCustom(String v1,String v2,String v3) {
        Criteria criteria = new Criteria("f1",v1);
        criteria.addCriteria("f2", v2); 
        criteria.addCriteria("f3", v3);
        fetchData(criteria);
}
}

When used this version the fetchCustom sends to server no fields in the criteria, altough ServerFilterFields is set with those 3 fields.
If setKeepParentsOnFilter and setServerFilterFields lines are commented out then fetchCustom sends the right criteria to server, but using the Filter Editor triggers a new server call with additional field/value.

I also tried to use on the tree grid:

ResultTree dataPropeties = new ResultTree();
dataPropeties.setKeepParentsOnFilter(true);
dataPropeties.setServerFilterFields("f1","f2","f3");
setDataProperties(dataPropeties);

but didn't work either.

Could you please advise what is wrong with that code?
I used the latest smartgwtpower-3.1p-2013-03-05.

Thanks,

There's nothing obviously wrong with this code and it matches automated tests that are passing. Lots of things could be happening:

1. criteria on serverFilterFields as produced by filterEditor not identical to criteria initially applied

2. missing / bad DataSourceField declarations for some fields

We'd need more information to help further, or ideally, runnable code where we can see the problem.

Hi. Could you maybe provide a showcase for treegrid with client-side filtering ?

We may add one in a future version.
