Question

When user changes background color for example, the Settings.settings file is modified. And it works.

But the application doesn’t change it’s background color after user clicks OK.
It works only when I close and build the application again.

How can I reload my form or user control on button click? (Tried with .Refresh(), but it doesn’t work)

    private void refreshSettings()
    {
        this.BackColor = Properties.Settings.Default.bgdColor;
        this.Font = Properties.Settings.Default.fontType;
        this.ForeColor = Properties.Settings.Default.fontColor;
    }

    private void Settings_Load(object sender, EventArgs e)
    {
        refreshSettings();
        bgdColorLBL.BackColor = Properties.Settings.Default.bgdColor;
        fontColorLBL.BackColor = Properties.Settings.Default.fontColor;
        fontTypeLBL.Font = Properties.Settings.Default.fontType;
        fontTypeLBL.Text = Properties.Settings.Default.fontType.Name;
    }

    private void okBTN_Click(object sender, EventArgs e)
    {
        LeagueUC lg = new LeagueUC();
        InitializeComponent();
        this.Close();
    }

    private void bgdColorLBL_Click(object sender, EventArgs e)
    {
        ColorDialog dlg = new ColorDialog();
        dlg.Color = Properties.Settings.Default.bgdColor;

        if (dlg.ShowDialog() == DialogResult.OK)
        {
            Properties.Settings.Default.bgdColor = dlg.Color;
            Properties.Settings.Default.Save();
            bgdColorLBL.BackColor = dlg.Color;
        }
    }

Run whatever code you have that sets the control’s properties at start up from the settings file.

e.g.

    private void bgdColorLBL_Click(object sender, EventArgs e) 
{ 
    ColorDialog dlg = new ColorDialog(); 
    dlg.Color = Properties.Settings.Default.bgdColor; 

    if (dlg.ShowDialog() == DialogResult.OK) 
    { 
        Properties.Settings.Default.bgdColor = dlg.Color; 
        Properties.Settings.Default.Save(); 

        Settings_Load(null, null);
    } 
}
