Hello drpoalim,Thank you for your posting. It is really helpful to share the personal approach so anyone else who is in your situation could benefit from your approach.
Thanks.
To simplify things, I have just added an ImageButtun below the chart, which has its width and height set to 0, and set focus
on it.
Hello drPolaim,Please let me know if you have any further questions regarding this issue.
Hello drPolarim,Thank you for posting in our community. This method is derived from the control class and is ment to be invoked when you want to set input focus. The Chart control is rendered as an image and is not input control. Please also take a look at the attached sample. If an image does not have tabIndex (our chart does not put such by default so you will have to inject it with jQuery) it could not fire its focus event (in the sample I have tested with ordinary <img>). Please modify your logic to use a html button in which to set the focus on the client for example.Please let me know if you need further assistance.
