Whats the equivalent for ng-grid's beforeSelectionChange in ui-grid?

In this section of the documentation: http://ui-grid.info/docs/#/api/ui.grid.selection.api:PublicApi

I see two events:

rowSelectionChanges and rowSelectionChangedBatch

What is the equivalent for beforeSelectionChange that was available back in ng-grid?

Why I need it and why I was using it in ng-grid?: When the user selects a row, an ajax call is performed. While this ajax call is happenning, I don’t want to allow the selection to be modified, so I used to do this:

    beforeSelectionChange: function () {
        return !($scope.doingAjaxCall);
    },

which locks selection if ajax is happenning

Sorry if it sounds pushy, but for me it is clearly a defect that ui-grid doesn’t have an easy way of disabling selection while an ajax call is happenning. ng-grid had an easy way for that.

defect: a shortcoming, imperfection, or lack.

ui-grid lacks this feature.

Regarding closing this question: maybe I should have written this question with the shape of a defect, and not as a question itself.

You may not be aware of it, but your tone is somewhat pushy in that last comment.

If we had stated that the new ui-grid was a superset of all ng-grid functionality, then yes it would be a defect if ui-grid didn’t have some things that ng-grid used to. However, we didn’t state that. ui-grid has many of the features of ng-grid and tried to keep similar interfaces where we could. But there’s no guarantee it has all the features of ng-grid.

ui-grid has a way to achieve what you are seeking to achieve, your issue was actually a question as to how to use that capability. Stack overflow is the correct place for questions.
