ExpansionPanel: Expand and Collapse event - get reference to sender

[Mikko]

Hello,

What is correct way to get ExpansionPanel's name that caused expand/collapse event? I would like to create general method to save expand panels expanded states.

By trial and error I have discovered that both expand and collapse event handlers seem to get some argument. This is argument is undocumented. My tests show that I can get ExpansionPanel name following way:

    function expand(e){
        var expandPanelName=$(e.item).attr("name");
        console.log(expandPanelName);
    }

Is this correct way to do it or can this be changed in future versions of Kendo?

Thanks
Mikko

Hello Mikko,

Indeed, this is the correct way to get the name of the ExpansionPanel that is expanded/collapsed. Here is a REPL sample that demonstrates it:

https://netcorerepl.telerik.com/QHYwlSbO485M7gls35

Both events provide the following event data:

• item - The ExpansionPanel HTML element.
• sender - The ExpansionPanel instance which fired the event.

We will update both server-side and client-side APIs with this information.

If any questions arise, please let me know.
