No, OpenFileDialog and SaveFileDialog are both derived from FileDialog , which is inherently modal, so (as far as I know) there's no way of creating a non-modal version of either of them. You can create a thread and have the thread host the OpenFileDialog. Example code is lacking any kind of synchronization but it works. public partial class Form1 : Form { OFDThread ofdThread; public Form1() { InitializeComponent(); } private void button1

问题 I have tried almost all of the jQuery Modal plugins I can find on the net but they are all much to bulky for what I need.

How to change MahApps.Metro dialog content template width?

阅读更多关于 How to change MahApps.Metro dialog content template width?

I would like to change the base template of the MahApps.Metro dialogs (or create a new dialog type), because I would like to show them in a narrow login window. Right now almost all the second words in the message are in a new row, but there are nice big spaces on the right and the left side, which I would like to reduce. I've found in BaseMetroDialog.xaml that the message dialog is divided into three parts vertically: 25% space on left side, 50% for the content and 25% space on the right side. I would like to change these numbers. But how could I change the control template of BaseMetroWindow
