order of grid initialization

[mathodParticipant]

Hello
I have a problem.
I have 2 grids, called Grid1 and Grid2.

CellClassName of Grid2 is depending of Grid1.
But sometimes, (I think), grid 2 is initialized before Grid1, and in CellClassName when i call this.Grid1.getRows(), it return me empty array.
And it’s why my cellClassName doesn’t work well.

Can i priorize an order to initialized my grids ?

Maybe, in ngOnInit, I can call grid1.refresh() and after grid2.refresh(). It seems to be working, but i don’t know if it’s the good way.

Thanks a lot

Hello mathod,

Yes, this is a possible solution. However, I think that it would be better to use the ngAfterViewInit lifecycle hook,
so you are sure the grids are created.
Another thing you can do is to use the rendered callback of the first grid and inside it to set the columns or refresh the second grid.

Thanks, I have resolved this problem.
But I have an other problem now..

My imageRenderer in my grid, is depending of a variable which is initialize by a get request in y constructor.

But, sometimes ( 1 time/2), my request grid is initialize before my get request called… So my var is undefined and my imageRenderer doesn’t work and I have this message :
undefined:1 GET http://localhost:4200/assets/setup/composition/undefined 404 (Not Found)

I understand this error, but I don’t know how can I call get request BEFORE grid Initialization…
Is it possible to initialize my grid After constructor call

thanks a lot

Maybe I can put my grid in a div :

<div *ngIf="GetRequestDone"> MY GRID </div>

Like that, my grid is created when my data are load…
But is it the good way ? …

Hello mathod,

Yes, this is a possible solution.
Otherwise, you can wait for the get request to finish and then update the grid’s columns with the imagerenderer.
