在WPF中将新页面居中

Question

I'm trying to center my program so that when it changes pages that it will remain centered. As it stands now, it starts off centered, but when I change the page it is no longer centered.

I've tried using the following code, but it doesn't work for a page. Thanks!

this.Left = (SystemParameters.PrimaryScreenWidth / 2) - (this.ActualWidth / 2);

this.Top = (SystemParameters.PrimaryScreenHeight / 2) - (this.ActualHeight / 2);

Answer 1

I don't have much idea about Page but Window do have Property WindowStartupLocation , This Property can have one of the three enum values 1)CenterScreen ,2) Manual , 3) CenterOwner , So if you want your MainWindow to be at Center of Screen then just set the property as

<myWindow:CustomPage x:Class="WpfApplication4.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:myWindow="clr-namespace:WpfApplication4"
    Title="MainWindow" Height="800" Width="800" WindowStartupLocation="CenterScreen">
<Grid>

</Grid>

I hope this will help.
