推荐答案

您可以使用javascript来做到这一点，例如

You can do this using javascript, something like this

document.getElementById('txt').focus();
document.getElementById('txt').value= "RoseIndia";

对于Button，我认为没有Focus事件.仅存在Click事件.
您可以尝试使用Click事件，对吗?

For Button I don''t think there is Focus event. Only Click event is present.
You can try with Click event, right?

您可以尝试这样做，以检查TextBox失去焦点时检查用户名的可用性.

You may try this for Check username availability on TextBox lost focus.
