I put some settings in the main form to change the appearance of the form. How to update all child forms? those. transfer data to other forms.

public main() { this.InitializeComponent(); this.StyleManager = metroStyleManager; } private void mbTheme_SelectedIndexChanged(object sender, EventArgs e) { switch (mbTheme.SelectedIndex) { case 0: metroStyleManager.Theme = MetroFramework.MetroThemeStyle.Dark; break; case 1: metroStyleManager.Theme = MetroFramework.MetroThemeStyle.Light; break; } } private void mbColor_SelectedIndexChanged(object sender, EventArgs e) { metroStyleManager.Style = (MetroFramework.MetroColorStyle)Convert.ToUInt32(mbColor.SelectedIndex); }
