Title: [1.4.5]Why treegrid doesn't support 0 parentid anymore
Post by: CLKG on July 28, 2016, 01:42:18 AM

Row will only display when it's _parentid is undefined or > 0.

I use 0 for root nodes, but it doesn't work in 1.4.5, and if I add loadFilter as:

for (var i = 0; i < data.rows.length; i++) {
if (data.rows._parentId == 0) {
data.rows._parentId = undefined;
}
}
return data;

Error will occurs when update rows cause a int field doesn't accept undefined, it's too complex for me to fix this problem, could you pls let _parentid supporting 0 again?

Please try this 'loadFilter' function.

Code:

$('#tg').treegrid({
	loadFilter: function(data){
		if ($.isArray(data)){
			return data;
		} else {
			$.map(data.rows, function(row){
				if (!row._parentId){
					row._parentId = undefined;
				}
			});
			return data;
		}
	}
})
