Keyboard support

As a part of Q2 2013 RadDropDownTree control introduces fully built-in Keyboard Support

  • Access Keys - You can specify a key that lets the end-users move the focus directly to the RadDropDownTree. The access key is defined using the AccessKey property. For example, if you set the AccessKey property to "P", the focus moves to the DropDownTree when the user presses "Alt+P" (for IE).dropdowntree-keyboardnavigation

  • Key Navigation- RadDropDownTree allows end-users to navigate through the nodes in the dropdown.

  1. Use the "Alt + DownArrow/UpArrow" to open/close the dropdown or the Esc key (to close the dropdown when opened)dropdowntree-expandcollapsedropdown

  2. Once the dropdown is opened you can move the focus to the filter field and then to the nodes by using the "Tab" key.dropdowntree-forwardnavigation

  3. After the focus is set to the dropdown the user can use the UpArrow and DownArrows to navigate up and down the tree and the RightArrow and LeftArrow to expand and collapse the nodes respectively.dropdowntree-navigationupdowndropdowntree-expandcollapsenode
