Keyboard interaction

9 Mar 20166 minutes to read

The Rotator property, AllowKeyboardNavigation, turns on the keyboard interaction with the Rotator items. You must set this property to true to access the keyboard shortcuts. The default value is true. The value set to this property is Boolean.

The entire Rotator commands are accessed through the keyboard by specifying the KeyboardShortcut in the following table.

KeyboardShortcut	Functions
Alt + j	Focuses the control
UP	Navigates up and left.
Down	Navigates down and right.
Left	Navigates up and left.
Right	Navigates down and right.
Home	Navigates to the starting item.
End	Navigates to the ending item.
Enter	Selects the focused item

In an ASPX page, add the following code example and set the AllowKeyboardNavigation property to true.

Add the following code in your JavaScript to focus the control.

JS

$(function () {



            //Control focus key

            $(document).on("keydown", function (e) {

                if (e.altKey && e.keyCode === 74) { // j- key code.

                    $("#<%=Keyboardevent.ClientID%>")[0].focus();

                }

            });

        });
