setfocus

问题 I am inflating a view when a button is pressed. The inflated view is like a dialog box, however when I try to get focus on the dialog box with requestFocus() , requestFocus() returns false means I am not getting focus on the view, but when I manually tap the inflated view, it recieves focus. What am I doing wrong? I clear focus from the button (which is used to inflated the new view) before I call requestFocus on inflated view.

However, when the partial postback returns and the calculated field is updated, the form focus is lost - the first field on the form gets focus back. Therefore the form is pretty

问题 I am validating user input in my viewmodel and throwing validation message in case validation fails for any of values. I just need to set the focus to the particular control for which validation has failed.

问题 I have a C# app with two forms. The first one is the main form which should always be open. The second one is a preview pane which the user can enable.
