I have a Window1.xaml main Window; and after some event, I display a UserControl EditFile.xaml. The code behind is: public static int whichSelected = -1; private void button1_Click(object sender, RoutedEventArgs e) { //searchEditPanel.Children.Clear(); whichSelected = listViewFiles.SelectedIndex; searchEditPanel.Children.Add(_EditFileControle); //this is Grid } And now, how can I close the opened/added UserControl from its content by clicking a Cancel button or something like that? Have you tried this? searchEditPanel.Children.Remove(_EditFileControle); Another Suggestion: Maybe this helps:

I've got a page with an iframe. The page and the source of the iframe are in different domains. Inside the iframe I'm using a rich text editor called CuteEditor (which has turned out to be not so cute). There are certain javascript functions in CuteEditor which try to access 'document' but the browser denies access since they're not in the same domain. Here's the exact error: Permission denied to access property 'document' http://dd.byu.edu/plugins/cuteeditor_files/Scripts/Dialog/DialogHead.js Line 1 Editing the javascript is out of the question because it's been minfied and obfuscated so all

Hy, In my MainWindow.xaml.cs file I made a getter to get the reference to my listbox. public ListBox LoggerList { get { return Logger; } } Now I want to access the LoggerList from a normal class but I don't work. I tried the following: MainWindow parentWindow = Window.GetWindow(this) as MainWindow; object selectedItem = parentWindow.LoggerList; But this only works in a *xaml.cs file and not in a normal *.cs file. Best regards There are a number of ways of accessing Window s in WPF. If you have several open, then you can iterate through them like this: foreach (Window window in Application

I want to put divider only between parent elements. When i set android:divider="@drawable/divider" android creates divider between parent elements, but creates divider between child elements too. When i add android:childDivider="@color/transparent" android removes the divider between child elements, but the free space between them remains. Why? I have tried to android:dividerHeight="0dp" but nothing happened. At all i want to set divider between parent elements, but i do not want any divider or empty space between child elements. any ideas how to do that?? Amala Ray In order to remove dividers

Almost every QtWidgets class can have parent. And usually it's optional to set parent at object initialization. For example,If I create a class that inherits QWidget class, I will do the following on the constructor: Widget::Widget(QWidget* parent): QWidget(parent) { hbox = new QHBoxLayout(this); yes_button = new QPushButton("&Yes"); no_button = new QPushButton("&No", this); cancel_button = new QPushButton("&Cancel", hbox); } I can set or not set parent. I can set cancel_button to be a child of hbox . I can too set cancel_button to be a child of yes_button , but I think it's a bad thing to do.

Process A fork() s process B. Process A dies and therefore init adopts B. A watchdog creates process C. Is it somehow possible for C to adopt B from init ? Update : Or would it even be possible to have C adopt B directly (when A dies), if C were created prior to A's dead, without init becoming an intermediate parent of B? Update-1: Also I would appreciate any comments on why having the possiblity to adopt a process the way I described would be a bad thing or difficult to impossible to implement. Update-2 - The use case (parent and children refer to process(es)): I have an app using a parent to
