treegrid : summary by group (or node)

[korenanzo]

Hi,

Is it possible to sum rows a nd show the result in the parent node?

I mean, if we take this as example,



in Wyoming, 2009/1st qrt. I'd like to have "6000" and so on.

If it is possible,then  should I prepare the summary data or there is an automagic summarizer?

thanks, RIk

You can prepare the summary data on your server side. Another way to solve this issue is to use the 'loadFilter' function to sum the data before loading it, or update these summary rows after loaded data successfully.

Code:

$('#tg').treegrid({
	loadFilter: function(data){
		...
		return newdata;
	},
	onLoadSuccess: function(){
		//...
	}
})
