i am using Listgrid of smartgwt api. i have set filter editor on the
list grid using setShowFilterEditor(). On UI, i can filter out the
list data from the particular columns using filter editor which is
shown on top of listgrid. till this, everything works fine. but
problem starts after this. my ListGridRecords are of type
ScreenInstanceGridRecord.
I cleared out the filter criteria before getting the ListGridRecord
from the ListGrid using method clearCriteria(), so that i can save all
the records to database ie. unfiltered records. when i try to get
records from the listgrid using getRecordList(), 1000 Dummy records
are added on the fly on first iteration, all my populated records are
ignored . and i need here is records of ScreenInstanceGridRecord type.
but on second iteration, i am getting my populated records which is of
ScreenInstanceGridRecord type. why this problem is occurring. i should
be getting ScreenInstanceGridRecord on the first iteration itself when
i try to get records from the ListGrid using getRecordList(). i am
getting no idea about this weird thing. any help from your side is
most welcome.. i am giving u piece of code which give u an idea where
i am getting problem
public void onModuleLoad() {
DataSourceIntegerField idSource = new
DataSourceIntegerField("id");
idSource.setPrimaryKey(true);
idSource.setHidden(true);
DataSourceTextField nameSource = new
DataSourceTextField("name");
DataSource ds = new DataSource();
ds.setFields(idSource, nameSource);
ds.setClientOnly(true);
final ListGrid grid = new ListGrid();
grid.setDataSource(ds);
grid.setShowFilterEditor(); // problem lies here
grid.setWidth(600);
grid.setHeight(400);
grid.setAutoFetchData(true);
grid.setAlternateRecordStyles(true);
grid.setShowAllRecords(false);
Button savebutton = new Button("Save");
saveButton.addClickHandler(){
grid.clearCriteria();
RecordList records = grid.getRecordList();
int length = recordList.getLength();
// On First Iteration, this method always giving me 1000 dummy
records. its doesnt matter how many records are populated in the grid.
but on second iteration, it is giving me right records length.
}
i don't know what the heck is happening here. i am very confused for
past 3 days. please give me some light on it.
