Hi,

Try the following code in MouseMove event of the CheckedListBox

Dim toolTip1 As New System.Windows.Forms.ToolTip



Private Sub CheckedListBox1_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles CheckedListBox1.MouseMove

        Dim pos As Point = CheckedListBox1.PointToClient(MousePosition)

        Dim index As Integer = CheckedListBox1.IndexFromPoint(pos)



        If (index > -1) Then

            toolTip1.SetToolTip(CheckedListBox1, CheckedListBox1.Items(index).ToString)

        End If

Try the below code, Change the code if your binding logic differ
DataTable c = new DataTable();
checkBoxColumns.DataSource = c;
checkBoxColumns.DataTextField = "Name";
checkBoxColumns.DataValueField = "column_name";
checkBoxColumns.DataBind();

foreach (DataRow row in c.Rows)
{
checkBoxColumns.Items[i].Attributes.Add("ToolTip", row.Cells[2].Text);
checkBoxColumns.ToolTip = row.Cells[2].Text;
i++;
}
