Hi,
The "something" that receives the focus before the first control is the page itself. If you have control over the page, you can add the some JavaScript code to your page to automatically focus the first control (or any other control) when the page receives focus:
Code: JavaScript
window.onfocus = function()
{
document.getElementById("control_you_wish_to_focus").focus();
}
We will also look into this and see if we can do this automatically on our end.
As to when switching application to another and back, that has to do with WPF focus management because it only manages the focus to the WebControl level without knowing anything inside the WebControl. We are not aware of any simple way to automatically restore focus in this case. We will look into this issue as well as we work on the above issue.
Thanks!
