How to use the ChildWindow
How to create and display a ChildWindow
- Create a new ChildWindow by right-clicking on your project in the Solution Explorer, and clicking Add => New Item => C# XAML for HTML5 => Child Window.
- To make the ChildWindow appear, use the following code:
var childWindow1 = new ChildWindow1();
Notes and other features
- If you want, you can give a title to your ChildWindow by setting it in XAML, like so: <ChildWindow Title="My Child Window" ...
- It is recommended that you give a fixed size (in pixels) to your ChildWindow, otherwise it may not show properly. You can do so by setting the size in XAML, like this: <ChildWindow Width="300" Height="200"...
- you want, you can register the "Closed" event to retrieve the dialog result. Here is how:
childWindow1.Closed += new EventHandler(ChildWindow1_Closed);
void ChildWindow1_Closed(object sender, EventArgs e)
var childWindow1 = (ChildWindow1)sender;
MessageBox.Show("The result is: " + childWindow1.DialogResult.ToString());
- You can set the result from within the ChildWindow using the following code:
this.DialogResult = true; // This will automatically close the ChildWindow.
If you want to pass a value other than boolean, you can add a property to your ChildWindow implementation and set it to the desired value.
- If you want, in your ChildWindow code, you can register the "Closing" event to check for data validity, and abort the closing operation by setting e.Cancel = true;
