The selection events in the RangeSelector
are not officially available yet, i.e. there is not OnRangeSelectorSelectionStart
event or anything similar. However, you can get information about the selection if you bind to the corresponding "select", "selectSart" and "selectEnd" events on the client-side:
"<%= Chart.ClientID %>"
//set the event-handlers for the events
//the event handlers - you can take the values of From and To from the event
" To: "
I also created a sample page where the selection events are demonstrated, so that you can test them on your own.
Regarding your second question - there are several XAxis
configurations which are supported for the Navigator's axis. You can have a look at our help article
about it and the general article about Configuring axes
. The kind of configuration you mentioned is not currently supported, but we plan to improve the navigation functionality, so we might consider implementing some useful features like this one.
On your third question - in general,
the performance of RadHtmlChart
is dependent on the number of individual chart elements that will be rendered on the page. There are several ways speed up the client-side rendering, e.g. hide all labels, disable the chart animation with Transitions="false"
, hide Minor
for the axes, etc.
