How to get and close a dialog in MahApps.Metro

Getting the current dialog

For IDialogCoordinator:

Task<TDialog?> GetCurrentDialogAsync<TDialog>(object context) where TDialog : BaseMetroDialog;

For MetroWindow:

Task<TDialog?> GetCurrentDialogAsync<TDialog>(this MetroWindow window) where TDialog : BaseMetroDialog;

Closing the dialog

To hide the dialog, use HideMetroDialogAsync with either IDialogCoordinator or MetroWindow.

For IDialogCoordinator:

Task HideMetroDialogAsync(object context, BaseMetroDialog dialog, MetroDialogSettings? settings = null);

For MetroWindow:

Task HideMetroDialogAsync(this MetroWindow window, BaseMetroDialog dialog, MetroDialogSettings? settings = null);

Example Usage

Here's an example of how to get and close a dialog using both IDialogCoordinator and MetroWindow.

Using IDialogCoordinator

var dialogCoordinator = DialogCoordinator.Instance;
var dialog = await dialogCoordinator.GetCurrentDialogAsync<MyCustomDialog>(context);
if (dialog != null)
{
    await dialogCoordinator.HideMetroDialogAsync(context, dialog);
}

Using MetroWindow

var myMetroWindow = Application.Current.MainWindow as MetroWindow;
var dialog = await myMetroWindow.GetCurrentDialogAsync<MyCustomDialog>();
if (dialog != null)
{
    await myMetroWindow.HideMetroDialogAsync(dialog);
}
