javascript - Angular ngGrid Tree Control: Make a round trip on group expand -

-

i trying use nggrid make of "tree-control" can build dynamically calling api's. nggrid allows grouping on rows, yet nature of requires rows present @ beginning. unfortunate fact api pull generation data file integrity monitoring system insanely slow , stupid. instead, wish build "tree" dynamically on expansion of each generation.

i trying inject children (ngrows) group-row (ngaggregate) on callback, yet not think calling correct constructor ngrows fact rows ignored control

through use of aggregatetemplate option on gridoptions nggrid, have been able intersept expansion of group quite easily. (maybe not easily, still)

i've replaced ng-click of default template:

ng-click="row.toggleexpand()"

with:

ng-click="$parent.$parent.rowexpanded(row)"

i know it's bit of hack, can later. now, gets job done.

the way discovered how work way $scope rowexpanded function setting breakpoint in nggrid's "row.toggleexpand" function , calling template so:

ng-click="row.toggleexpand(this)"

once retrieve group want, call api children said group. need make return children of row. decided calling nggrid's ngrow factory:

row.children = []; for(var = 0; < childdata.length; i++) {     row.children[row.children.length] = row.rowfactory.buildentityrow(childdata[i], i); } row.toggleexpand();

... yet not appear working. rows not showing after expand! why won't rows show up?

here's current plunker!

by way

i've placed debugger statement within group-expand callback. long have debugger open, should catch breakpoint on expansion of group.

thanks everybody!

i found answer, i'm idiot....

i got control working, , realized total hack, have used control way meant used , have worked better, had better work-flow, , have saved me entire day of development. if wondering how use control way, answer don't.

i got stupid thing work updating data structure after round trip , forcing grid refresh, pretty obvious. had set grid options groups expanded , had control collapser icon logic myself, outside of nggrid. never called row.toggleexpand. hid rows null values function call within ng-if on rowtemplate. after said , done, put foot in mouth.
