You demands seems strange. :-) May be MultiColumn = true mode may help? Anyway I found one way to do something that looks like what you want: namespace ScrollTwoLists { public partial class Form1 : Form { public Form1() { InitializeComponent(); this.checkedListBox1.SelectedValueChanged += new EventHandler(checkedListBox1_SelectedValueChanged); this.checkedListBox2.SelectedValueChanged += new EventHandler(checkedListBox2_SelectedValueChanged); } void checkedListBox2_SelectedValueChanged(object sender EventArgs e) { if (this.checkedListBox2.SelectedIndex != this.checkedListBox1.SelectedIndex) { this.checkedListBox1.SetSelected(this.checkedListBox2.SelectedIndex true); } } void checkedListBox1_SelectedValueChanged(object sender EventArgs e) { if (this.checkedListBox2.SelectedIndex != this.checkedListBox1.SelectedIndex) { this.checkedListBox2.SetSelected(this.checkedListBox1.SelectedIndex true); } } } }
