Hello,
I am using the Ext.Net example http://examples.ext.net/#/Keys/KeyNav/Basic/ and i have modified the page illustrate the issue i am having with the container panel scrolling when not necessary. The code markup is shown below. When i move the window to the right or down with the arrow keys, the container panel scrolls even though it is not necessary. How can i stop the container panel from scrolling unless it is necessary? Thanks.
