copied!<p>Here's some code snippets for my homebrewed control:</p> <pre><code>public partial class DaysOfWeekPicker : UserControl { public event EventHandler ValueChanged; private DaysOfWeek myValue; [DefaultValue (0)] public DaysOfWeek Value { get { return myValue; } set { myValue = value; RefreshData (); } } public DaysOfWeekPicker () { InitializeComponent (); } private void DayOfWeekClick (object sender, EventArgs e) { if (Object.ReferenceEquals (sender, g_l_Sunday)) { this.Value = this.Value ^ DaysOfWeek.Sunday; } else if (Object.ReferenceEquals (sender, g_l_Monday)) { this.Value = this.Value ^ DaysOfWeek.Monday; } else if (Object.ReferenceEquals (sender, g_l_Tuesday)) { this.Value = this.Value ^ DaysOfWeek.Tuesday; } else if (Object.ReferenceEquals (sender, g_l_Wednesday)) { this.Value = this.Value ^ DaysOfWeek.Wednesday; } else if (Object.ReferenceEquals (sender, g_l_Thursday)) { this.Value = this.Value ^ DaysOfWeek.Thursday; } else if (Object.ReferenceEquals (sender, g_l_Friday)) { this.Value = this.Value ^ DaysOfWeek.Friday; } else if (Object.ReferenceEquals (sender, g_l_Saturday)) { this.Value = this.Value ^ DaysOfWeek.Saturday; } } private void RefreshData () { SetLabelDisplay (g_l_Sunday, (this.Value & DaysOfWeek.Sunday) == DaysOfWeek.Sunday); SetLabelDisplay (g_l_Monday, (this.Value & DaysOfWeek.Monday) == DaysOfWeek.Monday); SetLabelDisplay (g_l_Tuesday, (this.Value & DaysOfWeek.Tuesday) == DaysOfWeek.Tuesday); SetLabelDisplay (g_l_Wednesday, (this.Value & DaysOfWeek.Wednesday) == DaysOfWeek.Wednesday); SetLabelDisplay (g_l_Thursday, (this.Value & DaysOfWeek.Thursday) == DaysOfWeek.Thursday); SetLabelDisplay (g_l_Friday, (this.Value & DaysOfWeek.Friday) == DaysOfWeek.Friday); SetLabelDisplay (g_l_Saturday, (this.Value & DaysOfWeek.Saturday) == DaysOfWeek.Saturday); if (this.ValueChanged != null) this.ValueChanged (this, EventArgs.Empty); } private void SetLabelDisplay (LinkLabel label, bool enabled) { if (enabled) { label.BackColor = Color.Black; label.ForeColor = Color.White; } else { label.BackColor = Color.White; label.ForeColor = Color.Black; } } } </code></pre> <p>There may be a better way to do the value comparisons, but this is just what I came up with very quickly.</p> <p>As far as the designer part of it goes, I won't put it in here because of its verbosity, but it's rather simple. Each day is represented by a LinkLabel with the click event set to DayOfWeekClick. Each LinkLabel is at (1,1) and is 2 pixels smaller in both dimensions from is parent Panel. Each parent Panel has a black ForeColor, giving a border effect. Each Panel is set to DockStyle.Left, and the overall control size is equivalent to panel.Width * 7, panel.Height.</p>
