Change event (=selection changed) fires on programatically selection changes

[Ricky]

Hello,

the change event in the grid handles selection changes.

This works fine but when I use grid.select(...) to select rows programatically, this also fire the change event. That is not desired and not the case for other controls. You cannot distinguish programatic changes from user changes this way (while you could always call a shared function from the change-event-handler and the programmatic change if required)!

Is this by design or a fix? Can it be influenced?

Hello Ricky,

Currently, the mentioned behaviour is expected as the selection is actually changed.

In this scenario, I can suggest using a flag to determine if the event is triggered after programmatically changing the selection. Then based on the flag to execute or not the desired code on the changed event.

This is a confusing as other controls does not work this way but if this is what you think it should be...

This is confusing as other controls (e.g. DropDownList, see http://docs.telerik.com/kendo-ui/api/javascript/ui/dropdownlist#events-select) do not work this way. Not firing the event when setting programatically or having a flag in the event arguments should be the way to go.

Hello Ricky,

Thank you for the feedback.

I will forward this to the developer's team.

As for the DropDownList, we especially added this as an important note as usually, firing the change event in this scenario is expected.
