问题 In my application I have an activity to add/remove/edit records inside a SortedMap . The activity is implemented as an extension of ListActivity . I have implemented custom ArrayAdapter for the collection items. Every ListView item (which corresponds to an underlying record) consists of TextView s, EditText s, and a Button to delete the record itself. The layout is roughly as follows: ListView ---------------------------------------------------- [TextView] [EditText] [TextView] [EditText]

问题 I have a handler for the TextBox's PreviewLostKeyboardFocus event. It fires when I leave the TextBox using the keyboard (Tab key) or the mouse (by clicking on another TextBox on the form). The handler takes a KeyboardFocusChangedEventArgs , which has a property named KeyboardDevice , which isn't null in either scenario (I was hoping to find null here when using the mouse). Question: How can I tell whether a user used the keyboard or the mouse to leave a WPF TextBox? 回答1: The e.KeyboardDevice

问题 I have a ExpandableListView in which i am loading custom layouts in both group and child views. They are having some edit text fields. When i click on the edit text, the soft keyboard appears, that time the list is reloaded, but focus will not be on the edit text. As a result the input i am typing is not entered in that edit text. If i clicked on the edit text again i can enter the values. But I want to regain its focus even after reloading the list view. I tried with storing the last clicked

问题 I have a website in ASP.NET (WebForms, NOT MVC) which has a survey form divided in several slides. Each slide has a next button that, obviously does a transition (client-side, not post back or remote request) to the next slide. In each slide I have several ASP.NET controls with their related validators. I want this validators to be triggered when I click the next button (or maybe when each input loses focus?). I remembered ASP.NET doing client side validation on lost focus, but maybe I'm

Determine Where Activation Is Going When A Form Is Deactivated

由 你离开我真会死。 提交于 2019-12-07 09:01:03
问题 Does anyone know of a way to determine which window is going to receive focus when a form is deactivated? 回答1: I found the answer. Instead of subscribing to the activated and deactivate events, handle the WM_ACTIVATE message (used for both activation and deactivation) in WndProc. Since it reports the handle of the window being activated, I can compare that handle to the handles of my forms and determine if focus is changing to any of them. const int WM_ACTIVATE = 0x0006; const int WA_INACTIVE

问题 I have a search screen in my WPF application. The screen is implemented as a UserControl in a TabItem of a TabControl. When the user switches to the Search tab, I want the focus to go into one particular field. So I added a Loaded event handler to the UserControl tag in the Xaml and I called the Focus method of the control I want to have the initial focus in the Loaded event handler. This worked great until I upgraded the Telerik control library I'm using today. Now, when I switch to the
