Question

I’ve created a custom ListBox like in here. Thing is it doesn’t raise any of the item specific events like DrawItem and SelectedIndexChanged.

Any idea why? Thanks.

It worked just fine when I tried this code:

  public partial class Form1 : Form {     MyListBox mList;     public Form1() {       InitializeComponent();     }      protected override void OnLoad(EventArgs e) {       mList = new MyListBox(this);       mList.Location = new Point(5, 10);       mList.Size = new Size(50, this.ClientSize.Height + 50);       for (int ix = 0; ix < 100; ++ix) mList.Items.Add(ix);       mList.SelectedIndexChanged += new EventHandler(mList_SelectedIndexChanged);     }      void mList_SelectedIndexChanged(object sender, EventArgs e) {       MessageBox.Show(mList.SelectedIndex.ToString());     }      protected override void Dispose(bool disposing) {       // Moved from Designer.cs file       if (disposing) mList.Dispose();       if (disposing && (components != null)) {         components.Dispose();       }       base.Dispose(disposing);     }    }
