Server-side gruping

[marchew]

I'm new to SmartGWT. I want to implement ListGrid with serverside gruping. I'm using version 5.1.

So far i managed to implement custom data source which feeds the grid with data but grouping is done on client only. Grid asks server for data but does grouping on his own.

What do i have to do to make Grid ask for grouping on the serverside?

Hi marchew,

client side grouping is not the same as Database group by. See this blog post and my example here.

I am aware of that. What i'm looking for is the same client interface (Grouping config dialog, etc.) but functionality implemented completely by me on the server.

I don't think this is possible, e.g. sending groupheader-rows from the server.
What is your usecase? Do you know ListGridField.setGroupTitleRenderer() and ListGridField.setGroupValueFunction()?

I think that ListGridField.setGroupValueFunction(), would do the trick if

java.lang.Object getGroupValue(java.lang.Object value,
                             ListGridRecord record,
                             ListGridField field,
                             java.lang.String fieldName,
                             ListGrid grid)

was asynchronous.
