Hello,
I work with 'groupConcurrentEvents'
Now I want all events to be expand/closedwhen a button is clicked.
Unfortunately I haven't found a solution for this yet.
Does anyone have an idea?
Thank you very much
You can find an example in the following demo:
Group Concurrent Events (Demo)
It shows how to add an expand/collapse icon to the row headers using the onBeforeRowHeaderRender event handler.
onBeforeRowHeaderRender
Thank you very much for the quick reply.
I wanted to do this without the event handler 'onBeforeRowHeaderRender'.
Only one row is processed here.
I'm looking for a way to use all events at once via a button (in a toolbar).
sorry but I can't edit the post. Actually I'm looking for something like this:
dp.rows.forEach(function (row) { row.expand(); });
