I needed a custom Input Dialog. So I created a CustomInputDialog class inherited from BaseMetroDialog.

I used this code to call the method:

public async Task<string> ShowCustomDialog(string message, string title)
{
    var metroDialogSettings = new MetroDialogSettings()
    {
        AffirmativeButtonText = "OK",
        NegativeButtonText = "CANCEL",
        AnimateHide = true,
        AnimateShow = true,
        ColorScheme = MetroDialogColorScheme.Accented,
    };

    var dialog = new CustomInputDialog(View, metroDialogSettings)
    {
        Message = message,
        Title = title,
        Input = metroDialogSettings.DefaultText
    };

    return await InvokeOnCurrentDispatcher(async () =>
    {
        await View.ShowMetroDialogAsync(dialog, metroDialogSettings);

        await dialog.WaitForButtonPressAsync().ContinueWith((m) =>
        {
            InvokeOnCurrentDispatcher(() => View.HideMetroDialogAsync(dialog));
        });

        return dialog.Input;
    });
}

Message, Title and Input are dependency properties of CustomInputDialog. This is working at my end.

Add close button to your dialog (which is in Resources) & hook up its Click event to close your dialog. For closing, use this.HideMetroDialogAsync(dialog); where this is MetroWindow instance.
