1. how can i get group index when i expand / collapse group ?


    in above script i am getting dynamic values from my array in each group row .

    but when i expand / collapse i can’t.

    is there any way to get these values ??

To get name when group expanding\collapsing you can use even “onGroupStateChanged”. Event handler has parameters:

value - key value of group
state - {bool} open state, true - opened

grid.attachEvent(“onGroupStateChanged”, function(value,state){
//any custom logic here
