Add row at top of grid

[Eralmidia]

Question

I'm replacing an old jquery ignite grid with a new igx one. In the old one, we added a new row at the top of the grid like this:

In the new grid, I'm starting the adding of a new row with the following code:

var row = this.grid.getRowByIndex(0);
row.beginAddRow();

This however seems to add a new row below the first row, which look odd:

How do I add a new row at the top of the grid?

This is not supported currently. I am changing the issue to a feature-request.

By the way we'll likely expose a public API function that will not require a row context. When one is not given it will add a row on top or can be used to start adding for an empty grid.

@Eralmidia , as you know rows are added at the bottom after the adding UI closes. Having an API that spawns the UI on top won't change this behavior. I am wondering if you are expecting that the row is added where the UI spawns for this scenario.

I am a bit reluctant to add a row at index 0 in the grid's data source because when this row is pushed server-side and the data is refreshed (barring any sorting applied) it will go to the bottom in the vast majority of use-cases.

@ChronosSF I think this was created in relation to #9429 when trying to use the undocumented beginaddrow. This requires a row index, but because of the virtualization you can't just choose any index I belive. But I noticed that #9429 is currently marked as in development. Does that mean that we will soon get a more documented metod to start adding a row through code? Will this method then automatically scroll to the last row in order to start the row adding? If it's standardized in some way inside the grid soon I belive we might just disregard this feature-request.

Yeah, beginAddRowByIndex was never meant to be public. The public API was attached to the RowComponent and required its context. We'll create a public function in grid-base (so it is inherited by all grid flavors) that would allow for spawning the UI at an arbitrary index. I was just wondering if this could create the expectation that the row would remain there after editing completes.
