问题 So I am trying to move a desktop program i made to an app for Windows 8.1 using Visual Studio 2013 . Datagrid was deprecated for this release so I am trying to translate those over to a ListView . I previously used ListViews in other desktop applications, but it looks like a lot has changed. The problem I am having is populating my ListView from my database.

问题 When the user edits a record, a XAML Popup shows a small form. The software keyboard appears when the user gives focus to a TextBox. This is good. OnKeyDown (if Enter ) I commit the user's changes. After the changes are committed, I hide the XAML Popup. The SIP remains visible even though the form is invisible. What is the correct way to handle this scenario? PS: this ( Show/Hide Keyboard programmatically on windows8 ) is not a solution to this problem. That's because the question is wanting

问题 in my Popup windows (contains game options control) I have "Reset HighScores" Button. Button fire a MessageDialog with a TextBlock "Are you sure that ..." and two Buttons "Yes" and "No". However, when MessageDialog opens, Popup closes.

问题 I have a Windows Store App that, of course, runs fine on my dev machine. After creating the package to side load for testing, I installed it on another (desktop) machine. Using the instructions for side-loading contained on pages 25 and 26 of Brundritt's free ebook "Location Intelligence for Windows Store Apps", my app seems to install just fine, except that the app is not added to the Windows 8.1 start screen at the end, as expected.
